Cat

Discover the fascinating world of domestic cats! From their varied species to their place in the Felidae family, learn everything you need to know about these beloved mammals.

Introduction To Domestic Cat

Cats began their unique relationship with humans 10,000 to 12,000 years ago in the Fertile Crescent, where some of the earliest developments in human civilization occurred (encompassing modern-day parts of West Asia). One such development was agriculture. The domestic cat, Felis catus, was originally domesticated in the Near East around 9,000 years ago. Cats have since spread across the globe and established themselves as valued pets in various cultures. Their wild ancestors can be traced back to ancient Egypt and Mesopotamia, it was through selective breeding that the modern domestic cat emerged. While today's domestic cats might seem far removed from their wild counterparts, they still possess some innate traits inherited from their ancestors and can be found in homes all over the world.

One interesting aspect of the domestic cat is its wide variety of breeds. Beyond their historical significance, domestic cats have evolved into diverse breeds with unique characteristics and personalities. From long-haired beauties like the Maine Coon to sleek and slender elegant Siamese cats to exotic Bengal cats with wild-like markings, there is a breed to suit every individual's taste and preference. These different breeds have been selectively bred over time to enhance certain traits such as coat pattern, size or temperament. This diversity adds another layer of intrigue to our feline friends and opens up endless possibilities for finding the perfect match for any household. 

Cats also possess remarkable sensory abilities and are gifted hunters due to their keen senses of hearing, curiosity and sight. Their retractable sharp claws and teeth are developed for catching prey and make them agile climbers, allowing them to explore their surroundings effortlessly. Despite their small size, they possess an air of majesty and grace that has captivated us since ancient times. With their playful nature and affectionate personalities, it's no wonder they have become such popular and beloved companions.

One intriguing aspect of domestic cats is their incredible adaptability. Unlike many other animals, they are not limited to specific habitats and can thrive in various environments. From city apartments to rural farms, cats have found a way to make themselves at home wherever they go. This adaptability is likely one of the reasons they were able to forge such a strong bond with humans throughout history.

Cats are natural hunters. Their genes still bear traces of their wild ancestors' hunting instincts, making them skilled ambush predators that can quickly pounce on unsuspecting prey. Even though they may not need to hunt for survival anymore, they exhibit tracking behaviours like stalking and pouncing on toys or moving objects. This behaviour not only satisfies their predatory instincts but also offers mental stimulation and exercise. Watching a house cat engage in strategic hunting tactics reminds us of their innate skills as skilled predators.

Despite their independence, domestic cats also fulfil an important role in human society by providing joy, companionship and emotional support. Numerous studies show that petting a cat can lower blood pressure and reduce stress levels, as well as improve overall mental well-being. Additionally, interacting with a cat releases oxytocin, often referred to as the love hormone, promoting feelings of happiness and bonding between humans and felines alike. These feline friends offer unwavering loyalty and affection to their human counterparts.

Scientific Name Of Domestic Cat

"Felis silvestris catus(Felis catus)" is the scientific name for the domestic or house cat, whose closest relative is the species Felis silvestris lybica, the African Wild Cat. The scientific name of the domestic cat is not just a random combination of words. It holds immense significance in the world of taxonomy and evolutionary history. The domestic cat belongs to the genus Felis and the subfamily Felinae of the family Felidae. It is also the smallest member of that family, which includes lions, tigers and pumas. The genus name Felis refers to all small wild cats, making it clear that our beloved furry companions share close ancestry with their wild relatives. The specific epithet catus, on the other hand, originates from the Latin word for domesticated. This reflects how these animals have been living alongside humans for thousands of years.

Close to 60 cat breeds are recognized by various cat breed registries. Just like other members of the family Felidae, cats are termed hypercarnivores.

Facts And Features About Domestic Cats

These furry felines have some truly incredible abilities that make them unique and fascinating creatures. This adorable feature not only gives them a distinctive appearance but also provides them with better balance and agility. Their unique physical features and extraordinary senses contribute to making them such intriguing companions in our lives.

  1. There are over 500 million pet cats in the world and there are over 60 different cat breeds. Cats are believed to be the only mammals who don't taste sweetness. They are the sleepiest of all mammals. Cats spend an average of 16 hours sleeping each day.
  2. They are good at detecting movement in low light. Cats have the largest eyes of any mammal in body size. They are partially colour-blind and are nearsighted but their peripheral vision and night vision are much better than that of humans. Their irises' structure is called the tapetum lucidum, a reflective layer located behind the retina which functions like a mirror reflecting incoming light into the eye. Cats can see up to 120 feet away and Blue-eyed cats are often prone to deafness.
  3. Cats are supposed to have 18 toes (five toes on each front paw; and four toes on each back paw). They can jump up to six times their length and can run up to 30mph. Domestic cats can navigate and find their way home over long distances.
  4. The domestic cat has a smaller skull and shorter bones than the European wildcat. It averages about 20-28 in head-to-tail length and 9-10 in height. Males are larger than females. Adult domestic cats typically weigh between 3.6 and 5.4 kg. The average age for an indoor cat is 13-20 years while the average age for an outdoor cat is only 3-5 years.
  5. They have an acute sense of smell and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk.
  6. Domestic cats have a remarkable ability to detect high-frequency sounds that humans cannot even perceive. Their ears contain over 30 muscles, allowing them to rotate up to 180 degrees, enhancing their auditory sensitivity. This highly evolved sense helps them locate their prey. 
  7. They have flexible bodies which allow them to squeeze through tight spaces with ease. Cats possess a unique skeletal structure that includes collarbones that are not completely attached, giving them greater flexibility in their shoulders and allowing them to slip through narrow openings. This exceptional ability comes from their evolutionary heritage as predators who needed to access small burrows or chase prey into cramped spaces. 
  8. Most people are familiar with the typical meow sound. A cat will rarely "meow" at another cat. This sound is mostly reserved for humans. Cats use a variety of noises to communicate with us and other animals. They communicate with fellow felines through subtle vocalizations and body language. Cats have 100 different vocalization sounds. They purr at the same frequency as an idling diesel engine, approximately 26 cycles per second.
  9. A domestic cat's skeletal system is built with more bones than any other mammal except dolphins. Their vertebrae count is astonishingly similar to that of humans, each having 7 neck bones or cervical vertebrae 
  10. Cats lap liquid from the underside of their tongue rather than from the top when drinking. The nose pad of a cat is ridged in a unique pattern, just like the fingerprint of a human. Another fact is that 1 year of a cat's life equals 15 years of a human's life.

Appearance And Anatomy Of Domestic Cat

When it comes to appearance and anatomy, domestic cats have been perfectly crafted over centuries of evolution into nature's stealthy hunters. The cat is a very adorable animal with a small face, a nose, a big mouth and a few whiskers under its nose. It has two enchanting eyes and two perky ears which are very sensitive to sounds. Cats have extremely strong nocturnal eyesight. They have four legs and paws with sharp claws. Cat has a tiny body covered with smooth fur and it has a furry tail as well. Breeds are either shorthaired or longhaired. Domestic cats are usually white, black, yellow or grey and sometimes have markings of a different colour. A pattern of dark stripes or swirls on a lighter background is called tabby.

They are powerfully built, with sleek bodies, large brains and strong teeth. The cat skull is unusual among mammals in having very large eye sockets and a powerful and specialized jaw. The teeth are adapted to three functions:

  1. stabbing (canines)
  2. anchoring (canines) and
  3. cutting (carnassial molars).

Cats have no flat-crowned crushing teeth and thus do not chew or grind their food but instead cut it. They are nearsighted, but their peripheral vision and night vision are much better than that of humans. The feline eye's pupils are supersized, bigger than humans and are controlled by two shutter-like ciliary muscles, which create that slit-like pupil seen in bright light. Light hitting feline eyes in the dark reflects off a mirrorlike membrane behind the retina called the tapetum lucidum.

Cats have sensitive ears that can move independently of each other. Because of this mobility, a cat can move its body in one direction and point its ears in another direction. Most cats have straight ears pointing upward. Their nose helps them to identify territories, other cats and mates, locate food and have various other uses. A cat's sense of smell is believed to be about fourteen times more sensitive than that of humans. The colour of the nose leather is probably dictated by a dedicated gene. 

Cats are believed to be the only mammals who don't taste sweetness. The cat's tongue is covered in a mucous membrane and they lap liquid from the underside of their tongue rather than from the top when drinking. The dorsal aspect has 5 types of sharp spines or papillae. The 5 papillae are filiform, fungiform, foliate, vallate and conical. A cat's sense of smell and taste work closely together, having a vomeronasal organ that allows them to use its tongue as a scent taster, while its longitudinal, transverse and vertical intrinsic muscles aid in movement.

In keeping with a carnivorous habit, the cat has a simple gut; the small intestine is only about three times the length of the body. They possess rather loose skin, which allows them to turn and confront a predator or another cat in a fight, even when it has a grip on them. A cat's skin has the same colour as the fur. The skin of the cat, composed of dermis and epidermis, regenerates and fights off infection quickly. Beneath their soft fur lies an intricate muscle structure developed for stealthy movements and lightning-fast reflexes.

Cats are also able to walk very precisely. They are supposed to have 18 toes (five toes on each front paw; and four toes on each back paw). They can jump up to six times their length. Like nearly all members of the family Felidae, cats have protractable claws. In their normal, relaxed position, the claws are sheathed with the skin and fur around the toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the forefeet are typically sharper than those on the hind feet. Cats can voluntarily extend their claws on one or more paws. They may extend their claws in hunting or self-defence, climbing, "kneading" or for extra traction on soft surfaces.

Their skeleton is not so different from the human skeleton. They have 230 bones and 13 ribs. Cats do have clavicles (collar bones) but unlike humans, they are not attached to other bones. Their elaborate spine construction gives cats the ability to twist, rotate, and bend effortlessly in all sorts of directions, making them formidable predators capable of capturing elusive prey like birds or insects.

It averages about 12-18 in head-to-tail length and 9-10 in height, with about 8-10 in long tails. Males are larger than females. Adult domestic cats typically weigh between 3.6 and 5.4 kg. Certain larger breeds can weigh as much as 25 pounds (11 kg) and smaller breeds can weigh as little as 5 pounds (2.2 kg).

Habitat And Distribution Of Domestic Cats

Domestic cats have a widespread habitat and distribution across the globe. They are known for their adaptability and can be found living in a wide range of habitats around the world. Initially descended from wildcats in Africa around 9,000 years ago, domestic cats can now be found in almost every country. These adaptable creatures are superb survivors and can thrive in a variety of environments. Domestic cats are found in areas where humans live but usually in rural areas where the main form of agriculture is grazing livestock. While they are commonly associated with urban environments, cats have also been able to thrive in suburban areas. They occur in many habitat types because they primarily live in human habitation. Many people associate them with cities and towns as they make themselves comfortable in our homes, cats can also be found living in feral colonies outside human settlements. This ability to adapt to different ecosystems is impressive considering their ancestors were desert-dwelling creatures. Cats do best in areas where winters are not severely cold.

In terms of distribution, domestic cats can be found on every continent except Antarctica. The domestic cat is descended primarily from the wild cat of Africa and extreme Southwestern Asia. They were first domesticated around 4,000 years ago in ancient Egypt and have since spread across the globe through human migration and trade routes. Cat is now distributed worldwide in association with humans, except for some isolated islands in the Pacific Southwest where they have not been introduced or where they have been introduced but have not established reproducing populations. Today, cats exist in a variety of different breeds and are found in homes, farms, cities and even on remote islands. The distribution of domestic cats has been heavily influenced by human intervention. For example, when Europeans colonized new parts of the world centuries ago, they often brought cats along on ships for pest control purposes. This led to the introduction and establishment of cat populations on various islands such as Australia or New Zealand where they had no natural predators and rapidly became invasive species impacting local wildlife populations.

Their presence has both positive and negative impacts on ecosystems depending on the habitat they inhabit. In urban areas, cats help control rodent populations but may also contribute to declines in bird populations if left unmonitored. In contrast, feral cat colonies can pose significant threats to native wildlife on islands or sensitive habitats where they disrupt delicate ecological balances.

Common Types Or Subspecies, Characteristics And Habitats Of Domestic Cats

Numerous types and subspecies of domestic cats vary in appearance, behaviour, temperament and traits. Each one offers something unique when it comes to these patterns. About 60 cat breeds are recognized by various cat registries. The popular types of cat breeds are the American Shorthair, the Persian cat, the Siamese cat, the Maine Coon, the British Shorthair, the Abyssinian cat, the Scottish Fold, the Sphinx cat,  the Bengal cat and the Ragdoll cat etc.

1. One of the most common types of domestic cats is the American Shorthair. These cats have a sturdy build, round faces, and dense short coats in a wide range of colours and patterns. They are known for their easygoing nature, making them great companions for families and individuals alike. The American Shorthair cats are native to the United States. Despite their relaxed demeanour, American Shorthairs are skilled hunters and exhibit strong instincts when it comes to catching prey.

2. One of the most popular and well-known domestic cat breeds is the Persian. These beautiful cats are known for their luxurious coats, flat faces, and calm demeanour. Persians come in a variety of colours and patterns, including solid, tabby, calico, and pointed. They are originated in Asia and are found in Europe and North America. being a low-energy breed that prefers a relaxed lifestyle indoors, they still require regular grooming to keep their long hair looking its best.

3. Another common type of domestic cat is the Siamese. Siamese cat is known for its striking blue almond-shaped eyes, sleek body and short coat. These cats are also famous for their vocal nature and affectionate personalities. They are often described as sociable and demanding. Siamese cats also have distinctive pointed markings on their coats, with darker colouration on their ears, face, paws, and tail. These cats are one of the oldest and most recognizable breeds. They originated in Thailand.

4. Another popular subspecies is the Maine Coon, a large breed with tufted ears and a bushy tail. Originating from North America, Maine Coons have a thick long-haired coat that helps protect them from harsh winters. Often referred to as gentle giants, Maine Coons are known for their friendly demeanour and love of attention.  Despite their imposing size, Maine Coons are gentle-natured companions who enjoy interacting with both humans and other pets.

5. The British Shorthair is another commonly seen type of domestic cat. These cats have compact bodies with dense fur that comes in various colours and patterns like tabby or solid grey-blue. They have round faces with expressive eyes and chubby cheeks that give them an adorable teddy bear-like appearance. British Shorthairs originated in Europe and are known for being independent but also enjoy spending time with their owners.

6. One notable type of cat is the Abyssinian cat. It originated in Southeast Asia. The Abyssinian cat is an ancient breed known for its stunning ticked coat that resembles that of wildcats. Abyssinians are highly active and intelligent cats who enjoy engaging in playtime with their owners. They love climbing heights and exploring everything around them due to their curiosity-driven nature. Abyssinians make for fascinating companions with their unique coat patterns and vibrant personality.

7. The Scottish Fold is another unique type of cat due to its distinctive folded ears that give it an owl-like appearance. This breed originated in Scotland, is incredibly playful and tends to develop strong bonds with their owners.

8. On the opposite end of the spectrum, there's the Sphinx cat. It is a hairless breed known for its wrinkled skin and it originated in Canada. Despite their lack of fur, these cats are surprisingly cuddly and demand plenty of warmth from their human companions.

9. The Bengal cat is an exotic-looking breed that draws inspiration from its wild ancestor, the Asian leopard cat. Bengals have a muscular build with a beautifully spotted or marbled coat reminiscent of big jungle felines. These cats are highly energetic and curious by nature but can also be quite affectionate towards their owners once they establish trust. Their playful antics make them excellent companions for families looking for an active pet. They are found in the United States and the South West Asia.

10. Lastly, there are the Ragdoll cats that melt hearts with their docile temperament and stunning blue eyes. They have a soft semi-longhair coat which comes in various colours and patterns. Their laid-back personality makes them great companions for those looking for a relaxed pet. The breed was developed in Riverside, California.

These are just a few examples of the wide variety of domestic cat types and subspecies out there today. 

Domestic short-haired cats are the most common kind of cat, accounting for around 96% of their number. It has won the hearts of many cat lovers worldwide. Originally brought to America by European settlers to control rodent populations on ships and farms, these adaptable felines quickly became beloved family pets due to their easygoing nature and low-maintenance coats. Other generic terms include house cat and alley cat (the latter may be used more specifically to refer to feral cats). But not recognised as a standardised breed by any major breed registry.

The cat's independent personality, grace, cleanliness, and subtle displays of affection have wide appeal. They are usually white, black, yellow or grey and sometimes have markings of a different colour. A pattern of dark stripes or swirls on a lighter background is called tabby. They can compress or elongate their spine, making them smaller to sleep in snuggly places or longer to leap across wide-open spaces. A cat will never sweat because it has no sweat glands. As mostly nocturnal animals, cats have excellent vision and hearing, with ears that can turn like satellite dishes. The cat is similar in anatomy to the other felid species. It has a strong flexible body, quick reflexes, sharp teeth and retractable claws. The muscles, tendons, joints, ligaments and spine of cats are extremely flexible, making them agile hunters. Cats have AB blood groups just like people and can donate blood to other cats. Domestic cats can be playful, affectionate, quiet, vocal, docile or calm but are often social, points out Trupanion. It is not an aggressive cat by nature, which makes it a terrific companion for children and seniors. Common domestic cats possess an uncanny ability for stealthy movements that puzzle even the most astute observers. These graceful creatures seemingly glide across rooms without making a sound, leaving behind nothing more than a gentle swish of their tails as they disappear into the shadows. It's no wonder they are often associated with mystical legends and folklore throughout history. Common domestic cats are far from ordinary pets, they carry within them stories of ancient civilizations and play vital roles in our everyday lives. From elegant Egyptian Maus to humble American Shorthairs, each breed brings its own charm and unique qualities to our homes.

House cats live on every continent in the world except Antarctica. The domestic cat covers a wide geographical range, from Antarctica to urban cities as well as temperate farmlands and is the most popular pet animal in America. Cats are most commonly found in the United States, which is recorded to have at least 76.5 million pet cats in total. Domestic cats primarily live in areas of human habitation and are somewhat constrained to developed areas. Most feral populations live close to current or past human settlements. Cats are adaptable animals and can live in various habitats, including homes, apartments and even outdoors. Domestic cats are thought to be descended from African wild cats and are found virtually worldwide in association with humans.

Diet And Prey Of Domestic Cats

The cat is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Domestic cats are known to be obligate carnivores, meaning their diet must consist primarily of meat. They evolved as hunters that consume prey that contains high amounts of protein, moderate amounts of fat and a minimal amount of carbohydrates. Their diet still requires these general proportions today.

Domestic cats are generally solitary hunters. The diet of wild or domestic cats is mainly made up of small rodents, such as mice and rats. Other common prey are moles, shrews, rabbits and birds. Small rodents (voles and mice) make up 40% or more of the feral domestic cat diet while young rabbits and hares may compose a large portion of the prey. These cats will prey on almost any small animal, such as birds, frogs, lizards, snakes and large insects but these are also taken in smaller amounts. This natural diet is high in protein and fat content, providing cats with essential nutrients for growth and maintenance. However, with the domestication of cats, their diet has become more diverse, often including commercial cat food or home-cooked meals. While some argue that feeding them a solely plant-based diet is possible, it's important to remember that their bodies are specifically adapted to metabolize animal protein efficiently. They also need a good balance of fat, carbohydrates, vitamins, minerals, fatty acids and amino acids, which are building blocks for protein. Cats' dietary needs change with age and health.

Despite being well-fed pets, many cats still exhibit their hunting behaviours. This is because the desire to chase and capture prey is deeply ingrained in their genetic makeup. The act of hunting stimulates both the physical and mental well-being of cats. Providing a balanced diet rich in protein also plays a vital role in keeping our feline companions happy and healthy by supporting muscle development and overall energy levels.

Behaviour And Lifestyle Of Domestic Cats

Cats may be behaviorally categorised as active, playful aggressive, calm and sociable or timid and shy. The way a cat behaves is individual and depends on its age, breed type and experience. Most cats are playful and sociable. Cats begin their social behaviours with biting, chasing and play fighting at around 4 wk of age, peak at 6-9 wk and decline at 12-14 wk. Cats like to play with toys and those that do not go outside often play at hunting indoors. The most common cat behaviours include purring, grooming, kneading and climbing. But each cat will engage in these activities differently. In multi-cat households or colonies living together in groups outdoors, dominance dynamics play a significant role in shaping their interactions.

Despite being well-fed pets, many cats still exhibit their hunting behaviours. Even though they may not need to hunt for survival anymore, they exhibit tracking behaviours like stalking and pouncing on toys or moving objects. This ability to live in such diverse settings is due in part to their natural hunting instincts, which allow them to catch prey no matter where they are. The act of hunting stimulates both the physical and mental well-being of cats. When they stalk their prey, their muscles are engaged in a workout similar to exercise routines recommended by veterinarians. Mentally, the thrill of chasing something ignites their instincts and can prevent boredom or stress-related behaviours often seen in indoor cats. Considering this aspect of their biology can help pet owners better understand why hunting toys or puzzles that mimic prey movements are not just additional playthings; they serve a crucial purpose for feline enrichment. Changes in behaviour may suggest that something is wrong with a cat's health. 

While cats are indeed capable of forming strong bonds with humans, their attention-seeking behaviours may go unnoticed or misinterpreted. For example, rubbing against the owner's legs or constantly wanting to sit on their lap can be seen as a simple nuisance rather than an affectionate gesture. By understanding these behaviours as displays of trust and love, owners gain a deeper appreciation for the complexity of the feline-human relationship.

The cat also changes its behaviour in response to the depressiveness of the human when close to the person but not at a distance, vocalizing more frequently with the person and head and flank-rubbing more often on that person. More demonstrative cats will sleep on or near their owners or other cats. 

Cats are crepuscular, which means that they're most active at dawn and dusk. They have a reputation for being more independent and aloof. Cats enjoy socialising with people and other cats. While they are known for their independent nature, many domestic cats form social groups called colonies when resources are abundant or when mating season is approaching. These colonies usually consist of related individuals who live together and share common resources. Some cats, especially those that live outdoors, may be less sociable with people and other animals. They are fastidious creatures in their "bathroom". If cat owners have more than one cat, they should have one litter box for each. Cats sleep for many hours each day and can spend up to a third of their waking hours grooming. Cats live longer when they stay indoors. Most cats sleep for about 10 hours, rest and nap for 5 hours, hunt for 4 hours, groom for 4 hours, eat for about 30 minutes and travel (outside of hunting movement) for about 1 hour. They are busy creatures.

Reproduction, Babies And Lifespan Of Domestic Cats

The reproduction process of domestic cats is a fascinating aspect that contributes to their ever-growing population. Unlike some species that have designated mating seasons, cats are known as "induced ovulators", meaning they can mate at any time during the year. Female cats can reach sexual maturity between 6 to 9 months of age. They can get pregnant up to five times a year. The number of cats rapidly increases without intervention by responsible and caring people. For example, 1 pair of breeding cats can exponentially produce 420,000 offspring over 7 years.

Cats also have an estrous or heat, cycle. However, female cats which are called queens, are induced ovulators. This means that they do not ovulate (pass an egg) unless they are bred. This dramatically increases the chances of conception when bred, which is why stray queens often have many kittens per year. During the estrus cycle, the queen becomes receptive to the male cat. Once the cats get together, the mating process doesn't last very long, only about half a minute to about 4 minutes. When a female persuasion is in heat, she can become pregnant quickly. So after a successful mating, females get pregnant at just four months of age and gestation begins. Since their gestation period lasts only for about 63-65 days on average or about two months. The first week of pregnancy is conception.

After mating the female will seem very agitated and will roll and thrash around. This is normal behaviour. On the other side, after getting pregnant there are some signs that she displays, such as becoming more affectionate, notable weight gain in a few weeks, pink-swollen nipples that appear around three weeks into the pregnancy, vomiting, distended abdomen, increased appetite, hiding more often and may sleep more than usual. All of these depend on how far along the pregnancy is. A female cat gives birth to a litter of kittens about two months after mating and may have two to three litters a year. The average litter is four to six kittens but there may be only one or as many as seven. A newborn kitten is about 3 inches (8 centimetres) long. A kitten is a juvenile cat.

When it comes to kittens, after being born these adorable bundles start blind and are fully dependent on their mothers for survival. Within one or two weeks after birth, their eyes begin to open gradually. Interestingly, the colour of a newborn kitten's eyes may not be permanent, they can change later from blue to green or yellow depending on genetic factors. They have 26 baby teeth, 12 incisors, four canines and 10 premolars (six on the top jaw and four on the bottom jaw). After their permanent teeth have come in, they will have 30 teeth, 12 incisors, four canines, 10 premolars and four molars. The playful stage quickly sets in when kittens are around three weeks old as they start exploring their surroundings and engaging in social interaction with their littermates and mother. Humans may also find kittens to be cute because they share similar qualities to human babies. Their expressive eyes, undulating tails, adorable paws and supple fur are very appealing. The emotions our kitties provoke are related to the feelings we feel when we see them. 

At about 6 months of age, a baby cat is called a kitten and about 6 to 8 months of age this kitten's life stage is the "teenage" years. At this stage, kittens are growing more independent, developing their social skills and mastering their environment. Almost all of their adult teeth are present by the end of this phase, which opens up the door to many kitten food options.

The lifespan of domestic cats is 12 to 18 years. While 13 to 17 years is the average life expectancy for an indoor cat, some live much shorter lives while others live well into their 20s. One kitty, Crème Puff, made it to the ripe old age of 38. In terms of lifespan, different factors affect how long domestic cats typically live. On average, indoor cats tend to live longer than outdoor ones due to reduced exposure to hazards such as traffic accidents or diseases carried by other animals. As responsible pet owners provide proper care including balanced nutrition and regular veterinary check-ups for preventive treatments and immunizations against common feline illnesses like respiratory infections or feline leukaemia virus (FeLV), domestic cats can live well into their late teens or even early twenties.

Predators And Threats Of Domestic Cats

Domestic cats may seem like invincible hunters but they face several predators and threats in their environment. One of the most common dangers for outdoor cats is other animals. The most common predators of domestic cats are dogs and foxes. House cats can be easy prey to animals such as coyotes and raccoons. These larger carnivores can easily overpower a cat if given the opportunity. Additionally, birds of prey like hawks and owls pose a threat to small cats, especially kittens or smaller breeds. Although cats are generally not hunted, they are susceptible to being preyed upon by wild animals under certain conditions.

Outdoor domestic cats are a recognized threat to global biodiversity. Another significant danger that domestic cats face is vehicular traffic. In urban areas, cars are also a major predator of cats. Cats that roam outdoors are at risk of being attacked by these predators. The curiosity and roaming nature of cats often lead them to wander on roads where they can be struck by passing vehicles. Furthermore, diseases pose a serious threat to domestic felines. Outdoor cats are at higher risk of contracting infectious diseases from other animals than indoor ones due to increased exposure. Life-threatening illnesses such as feline immunodeficiency virus (FIV) or feline leukaemia virus (FeLV) can be transmitted through fights with infected individuals or sharing contaminated food sources. The best way to protect these cats from these predators is to keep them indoors or supervise their outdoor activities closely.

Population Of Domestic Cats

The population of domestic cats has been steadily increasing over the years, raising concerns about their impact on local ecosystems. Approximately 600 million pet cats reside with humans worldwide. As of 2021, the number of owned cats in the world is estimated to be 220 million, while the number of stray cats is estimated to be 480 million. It is estimated that there are roughly 600 million cats on the planet in total. 

With an estimated 74 million pet cats in the United States alone, these furry companions have become a dominant force in urban and suburban areas. Of course, this doesn't account for their number of strays, which is said to be over 41 million. India also has 3 million cats as pets. While they provide comfort and companionship to millions of people, studies suggest that their presence is not without consequences.

Importance Of Domestic Cats

Cats are commonly kept as house pets and are valued by humans for companionship with their ability to kill vermin. They offer an unconditional love that can be equal to (or sometimes even greater than) many human friends and confidants.

  1. Cats are beneficial to physical and mental health and can also be a source of emotional support for their owners. The presence of cats can help reduce stress levels and increase feelings of happiness with relaxation. Their purring alone has been proven to have a calming effect on humans, making them perfect furry therapists after a long day. Owning a cat has been linked to improving mental health conditions such as depression and anxiety.
  2. It is fascinating how the simple act of stroking a cat's soft fur can release endorphins in our brains that promote feelings of euphoria. While these feline friends may not be nice to home furniture they can be a great companion and make lives happier and healthier. 
  3. Cats are important to society from keeping us sane and healthy to protecting foodstuffs from vermin and people from the plague, cats have done a lot for us.
  4. Domestic cats play an important role in pest control. With their hunting instincts intact, they keep homes free from unwanted creatures such as mice and rats. This natural ability to hunt not only helps protect our living spaces but also supports environmental balance by reducing populations of harmful rodents and preventing the spread of diseases carried by these pests.

Classification And Evolution Of Domestic Cats

One of the most fascinating aspects of domestic cats is their classification and evolution. The Felidae wild cat family is classified as one of the cat-like families (Feliformia) that belong to the carnivorous group (Carnivora) of mammals. The Felidae lower classifications are divided into two subfamilies,

  1. Pantherinae and
  2. Felinae.

The domestic cat, Felis catus, is a species of the genus, Felis. It belongs to the subfamily Felinae, of the family Felidae. The domestic cat is descended primarily from the wild cat of Africa (Felis lybica) and extreme Southwestern Asia. There are over 60 different breeds. However, domestication has led to various breeds with distinct physical characteristics and temperaments. The classification of domestic cats can be further broken down into different groups based on specific traits. One common way to classify them is by their coat patterns, which can range from solid colours like black or white to tabby stripes or spots. Another classification approach focuses on body types, with categories such as long-haired and short-haired cats or slim-bodied and stocky-built breeds.

The domestic cat originated from Near-Eastern and Egyptian populations of the African wildcat, Felis silvestris lybica, which means "cat of the woods". The family Felidae, to which all living feline species belong, arose about ten to eleven million years ago. This family is divided into eight major phylogenetic lineages. Understanding the evolution of domestic cats is also essential in appreciating their unique qualities. Through selective breeding over the centuries, humans have shaped these animals' characteristics for various purposes. For example, some breeds were developed for their hunting abilities while others were bred for their distinctive appearances or friendly personalities.

Relationship With Humans

Domestic cats have had a complex and intriguing relationship with humans for centuries. While some cats may seem aloof or independent, they have evolved to develop unique bonds with their human caretakers. These relationships go beyond basic companionship and friendship with cats showing signs of attachment to their owners similar to those seen in dogs. This suggests that they may rely on us not only for food and shelter but also for emotional support. Cats can, indeed, feel affection for humans and have a lot of the same emotions that we do, including liking to be around us and enjoying our presence.

One interesting aspect of the domestic cat-human relationship is the mutual benefit it provides. Cats have mastered the art of subtly communicating their needs and desires through a sophisticated repertoire of vocalizations, gestures and body language. Their purring has been found to serve as a form of communication that signals contentment or invites attention from humans. Additionally, cats use an array of facial expressions, tail movements and eye contact to convey various messages. With all of these, cats provide comfort, companionship and entertainment to humans, while humans fulfil their basic needs for food, shelter and veterinary care. 

Another captivating facet of this bond is how it can benefit both parties involved. Numerous studies have highlighted the positive impact that having a cat can have on human health and well-being. Petting a cat has been shown to reduce stress levels by promoting the release of oxytocin, known as the cuddle hormone, while also lowering blood pressure. Furthermore, living with cats has been linked to decreased risk of cardiovascular diseases such as heart attacks or strokes. Cats are thought to be able to improve the general mood of their owners by alleviating negative attitudes. Many cat owners report feeling immense satisfaction when caring for their feline friends, which can improve mental well-being and reduce stress levels.

Conservation Status Of Domestic Cats

Domestic cats, with their adorable antics and comforting presence, have become an integral part of our lives. However, few people realize that these seemingly abundant creatures are facing their conservation challenges. The domestic cat, or Felis catus, is not considered a threatened species globally. Nevertheless, some populations of feral cats and specific cat breeds face significant threats.

Feral cats, descendants of once-tamed pets or abandoned housecats, can pose a serious threat to native wildlife. They hunt small mammals and birds and have been known to decimate local populations in certain areas. Feral cats are listed among the top 100 invasive species worldwide by the International Union for Conservation of Nature (IUCN). To mitigate this impact on biodiversity, many countries employ trap-neuter-return programs to control feral cat populations while preventing them from further endangering native fauna.

Moreover, some specific cat breeds are at risk due to genetic factors associated with selective breeding practices. Breeds such as the Scottish Fold and Munchkin suffer from inherent health problems such as heart disease and spinal abnormalities respectively. As a result of these conditions being linked to their unique physical characteristics desired by breed enthusiasts, breeders must exercise caution to ensure the long-term health and welfare of these cherished pets.

Differences Between Domestic Cats And Wild Cats

The differences between domestic cats and wild cats may seem obvious at first glance but several intriguing aspects set them apart. While both species belong to the same family, Felidae, their behaviours and characteristics diverge greatly due to their different environments and evolutionary paths.

  1. One of the most prevalent distinctions lies in their hunting behaviour. Domesticated cats have become dependent on humans for food but they may still display some instinctual behaviours like hunting. In contrast, wild cats maintain their independence and fierce territorial nature. They are adept hunters, relying on their sharp claws and strong jaws to catch prey. 
  2. Domestic cats typically have a smaller territory that they consider their own, such as a house or yard, while wild cats roam vast expanses of land in search of food and mates. This broader territory necessitates a greater adaptation to environmental conditions by wild cats compared to domestic ones.
  3. Socialization patterns vary among domestic and wild cat species. Domesticated felines tend to form strong bonds with humans and other pets in the household, exhibiting affectionate behaviours like purring and kneading. Wild cats, on the other hand, are more solitary creatures who interact primarily for mating purposes or when raising their young.
  4. Domestic cats come in a wide variety of breeds that showcase an array of coat patterns and colours, while wild cats have distinct markings that help them blend into their natural habitats effectively. Conversely, domesticated cats typically have softer fur to enhance comfort in indoor environments.
  5. Wild cats have slightly larger brains (for their size) than domestic cats. Domesticated felines have vertical-slit pupils, while wild cats have round pupils.
