Felis catus
Independent, graceful and quietly affectionate - the world's most popular indoor companion.
View Cat breedsThe Cat's place in the tree of life, from domain down to species.
The cat (Felis catus) is a small domesticated carnivore kept worldwide as a companion animal. Adults usually weigh 3.5 to 5.5 kg and live 12 to 18 years with good care.
The cat is one of the most common companion animals in the world. It is a small, agile carnivore that has lived alongside people for thousands of years while keeping much of its independent nature. Cats are adaptable and can settle into apartments, houses, and rural properties, which is part of why they are kept across so many climates and cultures.
As pets, cats are valued for their relatively low daily demands compared with many other animals their size. They groom themselves, use a litter tray indoors, and do not need to be walked. Most cats form strong attachments to the people they live with, though the degree of affection and sociability varies a great deal from one animal to another.
Cats remain natural hunters. Even well-fed pets will stalk, pounce, and play, and this instinct shapes how they behave and what they need from their environment. A cat that has outlets for hunting-style play and places to climb and hide tends to be calmer and easier to live with.

| Diet | Obligate carnivore |
| Care level | Low to moderate |
| Best suited to | Households wanting an affectionate, largely self-sufficient indoor companion |
Cats suit people who want companionship without the constant supervision a dog needs. They fit busy households, smaller homes, and owners who are out for part of the day, provided the cat has food, water, a clean litter tray, and some enrichment. They are also a reasonable choice for first-time pet owners willing to learn basic care. Cats are a long commitment, often 15 years or more, so they suit people ready to plan for that span.
There are roughly 100 recognized cat breeds, though most pet cats are mixed-breed domestic shorthairs and longhairs rather than pedigreed animals. Breeds differ in coat length, body type, color, and temperament.
Estimates of the number of distinct cat breeds vary by registry, with around 102 commonly cited. Despite this number, the large majority of pet cats worldwide are not pedigreed. They are mixed-breed cats usually described simply as domestic shorthairs or domestic longhairs.
Where breeds do differ, the main axes are coat length and texture, body build (from slim and long-limbed to stocky and rounded), head shape, color and pattern, and broad temperament tendencies. Some breeds were developed for a particular look, such as a curled ear or a short tail, while others are tied to a geographic origin.
| Breed or type | Known for |
|---|---|
| Abyssinian | Slender, active build and a ticked coat |
| American Shorthair | Sturdy general-purpose shorthaired cat |
| American Curl | Ears that curve backward away from the face |
| American Bobtail | A naturally short, stubby tail |
| Bengal | A spotted or marbled coat resembling a wild cat |
| Balinese | Longer-coated cat in the pointed Siamese style |
| Birman | Pointed coat with white feet |
| Australian Mist | Spotted or marbled shorthaired cat developed in Australia |
Cat registries group breeds in several ways: by coat length (shorthair versus longhair), by body type, and by accepted color and pattern classes within each breed. A breed is defined by a written standard describing its ideal appearance, and a pedigreed cat is one with documented parentage matching that standard. Mixed-breed cats are not assigned to a breed, only to general type.
Cats were domesticated from the African wildcat in the Near East, with evidence of close association with people going back around 10,000 years. They spread worldwide largely through human travel and trade.
The domestic cat descends from the African wildcat, a small wildcat native to the Near East and North Africa. The relationship began around 10,000 years ago in the Fertile Crescent, when early farming communities stored grain that attracted rodents. Wildcats that tolerated people and hunted those rodents found a reliable food source, and a loose partnership formed.
One of the earliest pieces of physical evidence is a burial on Cyprus, dated to roughly 9,500 years ago, in which a cat was interred near a person. Because cats are not native to Cyprus, the animal must have been brought there by boat, which points to people already keeping cats at that time.
Cats became prominent in ancient Egypt, where they were associated with several deities and were sometimes mummified. From the eastern Mediterranean, cats spread along trade and shipping routes throughout the ancient world, valued for controlling rodents in stores, homes, and on ships. This maritime role carried them across Europe and, much later, to the Americas and other regions.
For most of their history cats were kept for pest control and were largely left to breed freely, so deliberate breeding is relatively recent. Organized cat fancy and the development of formal breeds date mainly from the late 19th century onward, when cat shows and breed standards began. Today the cat is among the most widespread domesticated animals on the planet.
Cats are small, muscular carnivores with retractable claws, flexible spines, and acute night vision. Adults typically weigh 3.5 to 5.5 kg, with wide variation in coat, color, and build between breeds.
Cats share a consistent underlying body plan. They are small and muscular with a flexible spine, light bones, and retractable claws that stay sharp because they are kept off the ground. Their eyes are large relative to the head and adapted for low light, giving them strong night vision, and their hearing extends well above the human range. Sensitive whiskers help them judge gaps and navigate in the dark.
The coat ranges from very short to long and flowing, in many colors and patterns including solid, tabby, pointed, spotted, and bicolor. A few breeds are nearly hairless. Most cats have a similar overall shape, so breed differences often come down to coat, color, ear and tail form, and how slender or stocky the body is.
| Trait | Typical range |
|---|---|
| Size | About 23 to 25 cm at the shoulder; around 46 cm body length |
| Weight | 3.5 to 5.5 kg for most adults; some larger breeds exceed this |
| Coat or covering | Short to long fur; a few breeds nearly hairless |
| Colors | Black, white, grey, orange, cream, brown, and many patterns |
| Distinguishing features | Retractable claws, vertical-slit pupils, mobile ears, long whiskers |
Appearance differs most in coat and silhouette. Slender breeds such as the Abyssinian have long legs and a fine frame, while others are rounder and heavier. Coat length runs from the short coat of the American Shorthair to the long coat of the Balinese. Specific features distinguish some breeds, such as the curled ears of the American Curl or the short tail of the American Bobtail. Color and pattern range widely even within a single breed.
Cats are territorial hunters that can be solitary or social depending on the individual and their environment. They communicate through body language, scent, and a range of vocalizations including the meow and purr.
Cats are predators built around hunting. Even pets that never catch prey will stalk, chase, and pounce in play, and these bursts of activity are often followed by long periods of rest and sleep. Many cats are most active around dawn and dusk.
Socially, cats are flexible. The wildcat ancestor is largely solitary, but domestic cats can live happily in groups when resources are plentiful, and they form bonds with people and other animals they grow up with. They are territorial and rely heavily on scent, marking familiar areas by rubbing their faces and bodies against objects. Conflict over space, food, or litter trays is a common source of stress in multi-cat homes.
Communication combines body language, scent, and sound. Tail position, ear angle, and posture signal mood, while purring, meowing, chirping, and hissing convey different messages. Adult cats meow mainly at people rather than at each other, a behavior shaped by domestication.
| Aspect | Typical |
|---|---|
| Sociability | Variable; ranges from aloof to highly affectionate by individual |
| Activity level | Bursts of high activity, often at dawn and dusk, with long rests |
| Vocalness | Moderate; some breeds and individuals are notably talkative |
| With people | Bonds with familiar people; many enjoy company on their own terms |
| With other animals | Can coexist with cats and dogs, especially if introduced young |
Routine cat care means fresh food and water, a clean litter tray, regular play, and grooming suited to the coat. Most cats are largely self-sufficient but still need daily attention.
Grooming needs depend on coat length. Shorthaired cats usually manage with a weekly brush, while longhaired cats often need brushing several times a week or daily to prevent mats. Most cats groom themselves thoroughly, so bathing is rarely needed. Trim claws every few weeks if the cat tolerates it, and check ears, teeth, and eyes during handling. Handle cats gently, support the body, and let nervous cats approach in their own time rather than restraining them.
Cats are obligate carnivores and must get nutrients such as taurine from animal-based food. A complete commercial cat food, fed by life stage, meets their needs.
Cats are obligate carnivores, meaning they depend on nutrients found in animal tissue and cannot thrive on a plant-based diet. They need a high level of animal protein and certain nutrients, notably taurine, that they cannot make in adequate amounts themselves. A diet lacking taurine can cause serious heart and eye problems. For this reason, most owners feed a complete commercial cat food formulated to supply the right balance.
Wet food, dry food, or a combination can all work. Wet food adds moisture, which matters because cats have a relatively low natural thirst drive. Portion sizes should match the cat's age, weight, and activity to avoid obesity, which is one of the most common nutrition-related problems in pet cats.
| Life stage | Diet | Notes |
|---|---|---|
| Kitten | Complete kitten food | Higher energy and protein; feed several small meals a day |
| Adult | Complete adult food | Feed to maintain a healthy weight; measure portions |
| Senior | Senior or adult food as advised | Monitor weight, teeth, and kidney health with the vet |
Treats should make up only a small share of daily calories, as a rough guide no more than around a tenth. A cat on a complete diet usually needs no extra supplements unless a vet advises one. Always provide clean, fresh water. Because some cats drink little, a water fountain or several water bowls and feeding some wet food can help keep them hydrated.
Cats commonly live 12 to 18 years and are generally hardy, but they are prone to dental disease, obesity, kidney disease, and parasites. Vaccination, parasite control, and regular checkups support long-term health.
Cats are generally robust animals, and with good care many live 12 to 18 years, with some reaching their early 20s. They are skilled at hiding illness, so owners should watch for subtle changes in appetite, weight, litter-tray habits, grooming, and activity, which are often the first signs that something is wrong.
Several conditions are common across the species rather than tied to one breed. Dental disease is very widespread, obesity is a frequent problem in indoor cats, and chronic kidney disease is a leading concern in older cats. Cats are also susceptible to internal and external parasites and to several preventable infectious diseases.
| Condition | Signs | Note |
|---|---|---|
| Dental disease | Bad breath, drooling, difficulty eating | Very common; helped by dental care and checkups |
| Obesity | Excess weight, reduced activity | Linked to overfeeding; raises other health risks |
| Chronic kidney disease | Increased drinking and urination, weight loss | Common in older cats; managed, not cured |
| Parasites | Itching, visible fleas, digestive upset | Controlled with routine preventive treatment |
| Lower urinary tract disease | Straining, frequent or bloody urination | Straining with no urine is an emergency |
Cats can be trained using reward-based methods to use a litter tray, accept handling, and learn simple cues. They respond to positive reinforcement, not punishment.
Cats are often described as untrainable, but this is a misunderstanding. They learn readily when training uses rewards they value, such as food or play. They do not respond well to punishment, which tends to cause fear and damage the bond rather than change behavior. The key is to reward the behavior you want and redirect the behavior you do not.
Most cats take to a litter tray with little effort because burying waste is natural to them. Beyond that, cats can learn to come when called, accept a carrier, tolerate nail trims and grooming, and perform simple tricks. Training sessions should be short, since cats lose interest quickly, and consistent across the household.
Female cats can reach sexual maturity by around four to six months and have a gestation of about 63 to 65 days, usually producing litters of three to five kittens.
Cats reach sexual maturity young, often around four to six months of age, though this varies with breed and time of year. Females are seasonally polyestrous, coming into heat repeatedly during longer-day periods until they mate. Cats are induced ovulators, meaning ovulation is triggered by mating, which makes successful breeding likely once a female is in heat.
Gestation lasts roughly 63 to 65 days. A typical litter is three to five kittens, though smaller and larger litters occur. Kittens are born blind and helpless and depend entirely on the mother at first. They open their eyes at around one to two weeks, begin weaning at about four weeks, and are usually fully weaned by eight weeks. Early handling and exposure to people and normal household life during the first weeks strongly shape how confident and sociable a cat becomes.
| Metric | Value |
|---|---|
| Sexual maturity | About 4 to 6 months |
| Gestation | About 63 to 65 days |
| Typical litter size | 3 to 5 kittens |
| Eyes open | Around 1 to 2 weeks |
| Weaning | About 8 weeks |
A cat is a 15-year-plus commitment of time and money, suited to people who can provide daily care, a safe home, and ongoing veterinary costs. Cats can come from breeders, shelters, or rescues.
A cat needs daily feeding, a clean litter tray, play, and attention, even though it is more self-sufficient than many pets. Consider the space you have, whether the cat will live indoors or have outdoor access, and how a cat fits with other pets and family members. Costs include food, litter, routine veterinary care, vaccinations, parasite control, and the possibility of unexpected medical bills, which can be significant. Most importantly, a cat often lives 15 years or more, so it is a long commitment that should outlast changes in home, work, and lifestyle.
| Item | Typical cost |
|---|---|
| Adoption or purchase | Low adoption fee up to a high price for a pedigreed kitten |
| Initial supplies | Litter tray, carrier, beds, bowls, scratching post |
| Food and litter | An ongoing monthly cost |
| Routine vet care | Annual checkup, vaccinations, parasite control |
| Neutering | A one-time procedure cost |
| Emergencies | Variable and potentially high; insurance can help |
Cats come from several sources. Shelters and rescue organizations have many cats and kittens of all ages needing homes, often already neutered and vaccinated. Responsible breeders are an option for those wanting a specific pedigreed breed; a good breeder lets you see the conditions, shares health information, and asks questions about the home. Avoid sources that cannot show where the cat was raised or that breed without regard for health and socialization.

Common questions about keeping a cat cover whether they make good pets, how long they live, typical costs, care difficulty, and suitability for families and beginners.
Yes. Cats are popular companions because they are affectionate yet relatively independent, adapt well to indoor life, and need less hands-on management than many other pets of similar size.
Most cats live about 12 to 18 years with good care, and some reach their early 20s. Indoor cats tend to live longer than those with unsupervised outdoor access.
Beyond the initial cost of the cat and supplies, expect ongoing spending on food, litter, and routine veterinary care, plus the possibility of larger bills for illness or emergencies. Pet insurance can help spread that risk.
Care is generally low to moderate. Cats groom themselves and use a litter tray, but they still need daily feeding, a clean tray, play, grooming suited to their coat, and regular veterinary attention.
Many cats do well in families and suit first-time owners. Children should be taught to handle cats gently and respect when the cat wants to be left alone, and very young cats need supervision around small children.
Yes. Many cats live entirely indoors, which protects them from traffic, disease, and other hazards. Indoor cats need enrichment such as climbing space, scratching posts, and interactive play to stay healthy and content.
It depends on the cats and the home. Some cats prefer to be the only pet, while others, especially those raised together, enjoy company. In multi-cat homes, provide enough food stations, litter trays, and resting spots to reduce conflict.
