The cat ( Felis catus), also referred to as the domestic cat or house cat, is a small Domestication carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable are adapted to killing small prey species such as mice and . It has a strong, flexible body, quick , and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator.
Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skills comparable to those of a young child. Cat communication includes , , trilling, , growling, , and body language. It can hear sounds too faint or too high in frequency for human ears, such as those made by . It secretes and perceives .
Female domestic cats can have from spring to late autumn in temperate zones and throughout the year in equatorial regions, with litter sizes often ranging from two to five kittens. Domestic cats are bred and shown at cat fancy events as registered . Population control includes spaying and neutering, but pet abandonment has exploded the global feral cat population, which has driven the extinction of bird, mammal, and reptile species.
Domestic cats are found across the globe, though their popularity as pets varies by region. Out of the estimated 600 million cats worldwide, 400 million reside in Asia, including 58 million pet cats in China. The United States leads in cat ownership with 73.8 million cats. In the United Kingdom, approximately 10.9 million domestic cats are kept as pets.
The forms might also have derived from an ancient Germanic word that was absorbed into Latin and then into Greek, Syriac, and Arabic. The word may be derived from Germanic and Northern European languages, and ultimately be borrowed from Uralic languages, Northern Sámi gáđfi, female stoat, and Hungarian hölgy, lady, female stoat; from Proto-Uralic *käďwä, female (of a furred animal).
The English , extended as pussy and pussycat, is attested from the 16th century and may have been introduced from Dutch language poes or from Low German puuskatte, related to Swedish language kattepus, or Norwegian pus, pusekatt. Similar forms exist in Lithuanian puižė and Irish language puisín or puiscín. The etymology is unknown, but it may be an onomatopoeia from using a sound to attract a cat.
A male cat is called a tom or tomcat (or a gib, if Neutering). A female is called a queen. Some sources write that queen refers solely to unspayed cats that are in an estrous cycle. (or sometimes a molly, if Spaying). A juvenile cat is referred to as a kitten, a term interchangeable with the now-obsolete word catling in Early Modern English. A group of cats can be referred to as a clowder, a glaring, or a colony.
In 2003, the International Commission on Zoological Nomenclature ruled that the domestic cat is a distinct species, namely Felis catus. In 2007, the modern domesticated subspecies F. silvestris catus sampled worldwide was considered to have probably descended from the African wildcat ( F. lybica), following results of phylogenetic research. In 2017, the IUCN Cat Classification Taskforce followed the recommendation of the ICZN in regarding the domestic cat as a distinct species, Felis catus.
The earliest known evidence for the occurrence of the domestic cat in Greece dates to around 1200 BC. Greek, , and traders introduced domestic cats to southern Europe. By the 5th century BC, they were familiar animals around settlements in Magna Graecia and Etruria. During the Roman Empire, they were introduced to Corsica and Sardinia before the beginning of the 1st century AD. By the end of the Western Roman Empire in the 5th century, the Egyptian domestic cat lineage had arrived in a Baltic Sea port in northern Germany.
The leopard cat ( Prionailurus bengalensis) was tamed independently in China around 5500 BC. This line of partially domesticated cats leaves no trace in the domestic cat populations of today.
During domestication, cats have undergone only minor changes in anatomy and behavior, and they are still capable of surviving in the wild. Several natural behaviors and characteristics of wildcats may have Preadaptation them for domestication as pets. These traits include their small size, social nature, obvious body language, love of play, and high intelligence. Their rigorous grooming habits and instinct to bury their bodily waste make them generally much less messy than other domesticated animals. Captive Leopardus cats may also display affectionate behavior toward humans but are not domesticated. House cats may mate with feral cats. Hybridization between domestic and other Felinae species is also possible, producing hybrids such as the Kellas cat in Scotland.
Development of cat breeds started in the mid 19th century. An analysis of the domestic cat genome revealed that the ancestral wildcat genome was significantly altered in the process of domestication, as specific were selected to develop cat breeds. Most breeds are founded on random-bred domestic cats. Genetic diversity of these breeds varies between regions, and is lowest in purebred populations, which show more than 20 deleterious .
The premolar and first molar together compose the carnassial pair on each side of the mouth, which efficiently shears meat into small pieces, like a pair of scissors. These are vital in feeding, because cats' small molars cannot chew food effectively, and cats are largely incapable of mastication. Cats tend to have better dental health than most humans, with decay generally less likely because of a thicker protective layer of Tooth enamel, a less damaging saliva, less retention of food particles between teeth, and a diet mostly devoid of sugar. Nonetheless, they are subject to occasional tooth loss and infection.
Most cats have five claws on their front paws and four on their rear paws. The dewclaw is proximal to the other claws. More proximally is a protrusion which appears to be a sixth "finger". This special feature of the front paws on the inside of the wrists has no function in normal walking but is thought to be an antiskidding device used while jumping. Some cat breeds are prone to having extra digits ("Polydactyl cat").
During a lofty fall, a cat reflexively twists and rights itself to land on its feet using its acute sense of balance and flexibility. This reflex is known as the cat righting reflex. A cat always rights itself in the same way, and it has enough time in falls of at least . This has been investigated as the "falling cat problem".
Cats' taste buds possess the receptors needed to detect umami. However, these receptors contain molecular changes that make them taste umami differently from humans. In humans, they detect the amino acids glutamic acid and aspartic acid; but in cats, they instead detect inosine monophosphate and histidine. These molecules are particularly enriched in tuna. Researchers argue why cats find tuna so Palatability: "the specific combination of the high IMP and free histidine contents of tuna, which produces a strong umami taste synergy that is highly preferred by cats." One researcher said, "I think umami is as important for cats as sweet is for humans."
Cats distinctly prefer food temperature around , similar to a fresh kill. Some cats reject cold food, which would signal to the cat that the prey is long dead and therefore possibly toxic or decomposing.
Cats conserve energy by sleeping more than most animals, especially as they grow older. The daily duration of sleep varies, usually between 12 and 16 hours, with 13 to 14 being the average. Some cats can sleep as much as 20 hours. The term "cat nap" for a short rest refers to the cat's tendency to fall asleep (lightly) for a brief period. Short periods of rapid eye movement sleep are often accompanied by muscle twitches, which suggests they are dreaming.
Behavioral and personality traits depend on a complex interplay between genetic and environmental factors. Scientific evidence is mixed about the popular belief that those traits are linked to coat colors.
Life in proximity to humans and other domestic animals has led to a symbiotic social adaptation in cats, and cats may express great affection toward humans or other animals. Ethology, a cat's human keeper functions as a mother surrogate. Adult cats live in a type of extended kittenhood, a form of behavioral neoteny. Their high-pitched sounds may mimic the cries of a hungry human infant, making them particularly difficult for humans to ignore. Some pet cats are poorly socialized. In particular, older cats show aggressiveness toward newly arrived kittens, which includes biting and scratching; this type of behavior is known as feline asocial aggression.
Redirected aggression is a common form of aggression which can occur in multiple cat households. In redirected aggression, there is usually something that agitates the cat: this could be a sight, sound, or another source of stimuli which causes a heightened level of anxiety or arousal. If the cat cannot attack the stimuli, it may direct anger elsewhere by attacking or directing aggression to the nearest cat, pet, human or other being.
Domestic cats' scent rubbing behavior toward humans or other cats is thought to be a feline means of social bonding.
Purring may have developed as an evolutionary advantage as a signaling mechanism of reassurance between mother cats and Breastfeeding kittens, who are thought to use it as a care-soliciting signal. Post-nursing cats also often purr as a sign of contentment: when being petted, becoming relaxed, or eating. Although purring is popularly interpreted as indicative of pleasure, it has been recorded in a wide variety of circumstances, most of which involve physical contact between the cat and another, presumably trusted individual. Some cats have been observed to purr continuously when chronically ill or in apparent pain.
The exact mechanism by which cats purr has long been elusive, but it has been proposed that purring is generated via a series of sudden build-ups and releases of pressure as the glottis is opened and closed, which causes the vocal folds to separate forcefully. The Larynx in control of the glottis are thought to be driven by a neural oscillator which generates a cycle of contraction and release every 30–40 (giving a frequency of 33 to 25 Hz).
Domestic cats observed in rescue facilities have 276 morphologically distinct facial expressions based on 26 facial movements; each facial expression corresponds to different social functions that are probably influenced by domestication. Facial expressions have helped researchers detect pain in cats. The feline grimace scale's five criteria—ear position, orbital tightening, muzzle tension, whisker change, and head position—indicated the presence of acute pain in cats.
Cat Animal cognition study is mostly from consideration of the domesticated cat. Living in urban environments has exposed them to challenges that require adaptive behaviors, contributing to cognitive development. Selective breeding and genetic changes have further influenced their intelligence. learn essential survival skills by observing their mothers, while adult cats refine their abilities through trial and error.
Cats also tend to play with toys more when they are hungry. Owing to the close similarity between play and hunting, cats prefer to play with objects that resemble prey, such as small furry toys that move rapidly, but rapidly lose interest. They become habituation to a toy they have played with before. String is often used as a toy, but if it is eaten, it can become caught at the base of the cat's tongue and then move into the , a medical emergency which can cause serious illness, even death.
Feral cats and free-fed house cats consume several small meals in a day. The frequency and size of meals varies between individuals. They select food based on its temperature, smell, and texture; they dislike chilled foods and respond most strongly to moist foods rich in amino acids, which are similar to meat. Cats reject novel flavors (a response termed neophobia) and learn quickly to avoid foods that have tasted unpleasant in the past. It is also a common misconception that all cats like milk or cream, as they tend to avoid sweet food and milk. Most adult cats are lactose intolerant; the sugar in milk is not easily digested and may cause soft stools or diarrhea. Some also develop odd eating habits and like to eat or chew on things such as wool, plastic, cables, paper, string, aluminum foil, or even coal. This condition, pica, can threaten their health, depending on the amount and toxicity of the items eaten.
Cats hunt small prey, primarily birds and rodents, and are often used as a form of pest control. Other common small creatures, such as lizards and snakes, may also become prey. Cats use two hunting strategies, either stalking prey actively, or Ambush predator until an animal comes close enough to be captured. The strategy used depends on available prey, with cats waiting in ambush outside burrows, but tending to actively stalk birds.
Certain species appear more susceptible than others; in one English village, for example, 30% of house sparrow mortality was linked to the domestic cat. In the recovery of ringed robins ( Erithacus rubecula) and dunnocks ( Prunella modularis) in Britain, 31% of deaths were a result of cat predation. In parts of North America, the presence of larger carnivores such as , which prey on cats and other small predators, reduces the effect of predation by cats and other small predators such as and on bird numbers and variety.
Another poorly understood element of cat hunting behavior is the presentation of prey to human guardians. One explanation is that cats adopt humans into their social group and share excess kill with others in the group according to the dominance hierarchy, in which humans are reacted to as if they are at or near the top. Another explanation is that they attempt to teach their guardians to hunt or to help their human as if feeding "an elderly cat, or an inept kitten". This hypothesis is inconsistent with the fact that male cats also bring home prey, though males have negligible involvement in raising kittens.
When cats become aggressive, they try to appear larger and more threatening by raising their fur, arching their backs, turning sideways, hissing, or spitting. Often, the ears are pointed down and back to avoid damage to the inner ear and potentially listen for any changes behind them while focused forward. Cats may also vocalize loudly and bare their teeth in an effort to further intimidate their opponents. Fights usually consist of grappling, slapping the face and body with the forepaws, and bites. Cats throw themselves to the ground in a defensive posture to rake their opponent's belly with their hind legs.
Serious damage is rare, because the fights are usually short, with the loser fleeing with scratches to the face and ears. More severe fights for mating rights may give deep punctures and lacerations. Normally, serious injuries from fighting are limited to infections from scratches and bites. Bites are probably the main route of transmission of the feline immunodeficiency virus. Sexually active males are usually involved in many fights and have battered faces. Cats are willing to threaten animals larger than them to defend their territory, such as dogs and Red fox.
Several males, called tomcats, are attracted to a female in heat. They fight over her, and the victor wins the right to mate. At first, the female rejects the male, but eventually, the female allows the male to mate. The female utters a loud yowl as the male pulls out of her because a male cat's penis has a band of about 120–150 backward-pointing penile spines, which are about long; upon withdrawal of the penis, the spines may provide the female with increased sexual stimulation, which acts to induce ovulation.
After mating, the female cleans her vulva thoroughly. If a male attempts to mate with her at this point, the female attacks him. After about 20 to 30 minutes, once the female is finished grooming, the cycle will repeat. Because ovulation is not always triggered by a single mating, females may not be impregnated by the first male with which they mate. Furthermore, cats are Superfecundation; that is, a female may mate with more than one male when she is in heat, with the result that different kittens in a litter may have different fathers.
The morula forms 124 hours after conception. At 148 hours, early form. At 10–12 days, implantation occurs. The gestation of queens lasts between 64 and 67 days, with an average of 65 days.
Based on a study of 2,300 free-ranging queens conducted from May 1998 and October2000, they had one to six kittens per litter, with an average of three kittens. They produced a mean of 1.4 litters per year, but a maximum of three litters in a year. Of 169 kittens, 127 died before they were six months old due to a trauma caused in most cases by dog attacks and road accidents. The first litter is usually smaller than subsequent litters. Kittens are weaned between six and seven weeks of age. Queens normally reach sexual maturity at 5–10 months, and males at 5–7 months. This varies depending on breed. Kittens reach puberty at the age of 9–10 months.
Cats are ready to go to new homes at about 12 weeks of age, when they are ready to leave their mother.
Neutering increases life expectancy; one study found castrated male cats live twice as long as intact males, while spayed female cats live 62% longer than intact females. Having a cat Neutering confers some health benefits, such as a greater life expectancy and a decreased incidence of reproductive neoplasia. However, neutering decreases metabolism and increases food intake, both of which can cause obesity in neutered cats. Pre-pubertal neutering (neutering at 4 months or earlier) was only recommended by 28% of American veterinarians in one study. Some concerns of early neutering were metabolic, retarded Epiphyseal plate, and urinary tract disease related.
The unwantedness that leads to the domestic cat being treated as an invasive species is twofold. As it is little altered from the wildcat, it can readily interbreed with the wildcat. This hybridization poses a danger to the genetic distinctiveness of some wildcat populations, particularly in Scotland and Hungary, possibly also the Iberian Peninsula, and where protected natural areas are close to human-dominated landscapes, such as Kruger National Park in South Africa. However, its introduction to places where no native felines are present also contributes to the decline of native species.
Public attitudes toward feral cats vary widely, from seeing them as free-ranging pets to regarding them as vermin.
In Australia, one study found feral cats to kill 466 million reptiles per year. More than 258 reptile species were identified as being predated by cats. Cats have contributed to the extinction of the Navassa curly-tailed lizard and Chioninia coctei.
Cats have been used for millennia to control rodents, notably Farm cat and aboard ships, and both uses extend to the present day. Cats are also used in the international fur trade and leather industries for making coats, hats, blankets, stuffed toys, shoes, gloves, and musical instruments. About 24 cats are needed to make a cat-fur coat. This use has been outlawed in the United States since 2000 and in the European Union (as well as the United Kingdom) since 2007.
Cat pelts have been used for superstitious purposes as part of the practice of witchcraft,
A few attempts to build a cat census have been made over the years, both through associations or national and international organizations (such as that of the Canadian Federation of Humane Societies) and over the Internet. General estimates for the global population of domestic cats range widely from anywhere between 200 million to 600 million. Walter Chandoha made his career photographing cats after his 1949 images of Loco, a stray cat, were published. He is reported to have photographed 90,000 cats during his career and maintained an archive of 225,000 images that he drew from for publications during his lifetime.
Pet humanization is a form of anthropomorphism in which cats are kept for companionship and treated more like human family members than traditional pets. This trend of pet culture involves providing cats with a higher level of care, attention and often even luxury, similar to the way humans are treated.
Ancient Greeks and Romans kept as pets, which were seen as the ideal rodent-killers. The earliest unmistakable evidence of the Greeks having domestic cats comes from two coins from Magna Graecia dating to the mid-fifth century BC showing Iokastos and Phalanthos, the legendary founders of Reggio Calabria and Taranto respectively, playing with their pet cats. The usual ancient Greek word for 'cat' was ailouros, meaning 'thing with the waving tail'. Cats are rarely mentioned in ancient Greek literature. Aristotle remarked in his History of Animals that "female cats are naturally Promiscuity". The Greeks later syncretized their own goddess Artemis with the Egyptian goddess Bastet, adopting Bastet's associations with cats and ascribing them to Artemis. In Ovid's Metamorphoses, when the deities flee to Egypt and take animal forms, the goddess Diana turns into a cat.
Cats eventually displaced as the pest control of choice because they were more pleasant to have around the house and were more enthusiastic hunters of mice. During the Middle Ages, many of Artemis's associations with cats were grafted onto the Virgin Mary. Cats are often shown in icons of Annunciation and of the Holy Family and, according to Italian folklore, on the same night that Mary gave birth to Jesus, a cat in Bethlehem gave birth to a kitten. Domestic cats were spread throughout much of the rest of the world during the Age of Discovery, as ships' cats were carried on to control shipboard rodents and as good-luck charms.
Several ancient religions believed cats are exalted souls, companions or guides for humans, that are all-knowing but mute so they cannot influence decisions made by humans. In Japan, the maneki neko cat is a symbol of good fortune. In Norse mythology, Freyja, the goddess of love, beauty, and fertility, is depicted as riding a chariot drawn by cats. In Jewish legend, the first cat was living in the house of the first man Adam as a pet that got rid of mice. The cat was once partnering with the first dog before the latter broke an oath they had made which resulted in enmity between the descendants of these two animals. It is also written that neither cats nor are represented in the water, while every other animal has an incarnation species in the water. Although no species are sacred in Islam, cats are revered by Muslims. Some Western writers have stated Muhammad had a favorite cat, Muezza. He is reported to have loved cats so much, "he would do without his cloak rather than disturb one that was sleeping on it". The story has no origin in early Muslim writers, and seems to confuse a story of a later Sufi saint, Ahmed ar-Rifa'i, centuries after Muhammad. One of the companions of Muhammad was known as Abu Hurayrah ("father of the kitten"), in reference to his documented affection to cats.
According to a myth in many cultures, cats have multiple lives. In many countries, they are believed to have nine lives, but in Italy, Germany, Greece, Brazil, and some Spanish-speaking regions, they are said to have seven lives, while in Arabic traditions, the number of lives is six. An early mention of the myth is in John Heywood's The Proverbs of John Heywood (1546):
The myth is attributed to the natural suppleness and swiftness cats exhibit to escape life-threatening situations. Falling cats often land on their feet, using an instinctive righting reflex to twist their bodies around.
