For this reason, cats prefer their food to be warm, as odors are released by heat. The cat’s tongue is covered by numerous sensory knobs called papillae, of which several types exist. This cat “radar” is vital to the cat’s ability to move about and hunt in low-light conditions. The guard hairs are long and stiff and cover the top layer of the cat’s coat, keeping it dry.
The eyebrows and hairs of the cheek, chin, legs, and ears are extremely sensitive to vibrations and provide cats with a great deal of information. The average length of a full-grown domestic cat is 28 inches (71 cm) for males and 20 inches (51 cm) for females. The earliest known association between cats and humans likely dates to the origins of agriculture in the Middle East, about 15,000–10,000 years ago. The following article deals with general characteristics of the domestic cat.
Because domestic cats are crepuscular hunters, they need only one-sixth of the illumination levels humans require to see well. But there is also a popular belief that domestic cats have a sixth sense—the ability to find their way home over long distances. However, regardless of the color or pattern on the outside, all domestic cats are genetically tabbies like their wildcat ancestors. As domestic cats spread around the world along trade routes, the species became well adapted to life with humans.
Dominant and recessive genes
Consequently, cats have retained their independent nature and can thrive as predators in the wild today. For an account of the relationship of the cat family to other carnivores, see carnivore. For information on larger cats, see their individual entries (such as lion, tiger, and leopard). However, purring also occurs in cats that are injured and in pain. The average weight of a household cat varies from 2.7 to 4.5 kg (6 to 10 pounds), although among non-pedigreed cats weights up to 12.7 kg (28 pounds) are not uncommon. Both lineages continued to breed with the African wildcat during their respective dispersals.
“Black,” “orange tabby,” “longhaired,” “shorthaired”—all are common categories by which cats are identified, advertised, and sought. The English legend of Dick Whittington details his journey from rags to riches due to his cat’s mousing prowess. The Greek writer Aesop made frequent mention of cats in his fables.

- For example, in many Western countries, a black cat is considered bad luck, though the same cat in Japan is considered an omen of good fortune.
- These sounds can be interpreted as greetings, demands, pleas, challenges, or warnings, depending on the tone.
- The senses of taste and smell are closely related in cats and, because of this, the aroma of food is vital to a cat’s enjoyment.
- The guard hairs are long and stiff and cover the top layer of the cat’s coat, keeping it dry.
- When a cat’s eyes shine, light is bouncing off a layer of cells behind the retina called the tapetum lucidum.
- In Greece evidence from art and literature indicates that the cat was present there from the 5th century bce, and tiles featuring cats appeared in China from 500 bce.
Except for the canines and molars, the cat’s teeth are more or less nonfunctional; most of the cheek teeth do not even meet when the mouth is closed. The construction of the shoulder joints permits the cat to turn its foreleg in almost any direction, allowing for quick turns when chasing prey. Most of the cat’s weight is centered on the front paws while walking. Typically, cats walk or run by moving the front and back legs on each side together.

Down and awn hairs are secondary hairs (also called the undercoat) and are more numerous than guard hairs. The cat’s tail is mobile and used for both balance and communication. The exception is breeds such as the Manx and the Japanese Bobtail, which have mutations that give them short tails or no tails at all. This design also makes it easier to precisely locate the source of sounds. This allows the ears to pivot toward the source of sounds, and the ear shape helps funnel sounds into the ears. This claw-sheathing mechanism is present in all species of the cat family except the cheetah.

It is also the smallest member of that family, which includes lions, tigers, and pumas.
Adaptations have occurred with changes in prey, but the basic body type has stayed the same. Cats that resemble today’s felids first appeared in the early Pliocene Epoch (5.3 to 3.6 million years ago), and they have continued into present times with remarkably few changes. It is thought that all true cat species evolved from this small civetlike predator. The first felinelike spinmills casino promo code mammal, Proailurus, evolved about 30 million years ago. Purring is a continuous, rattling hum and often is interpreted as an expression of pleasure or contentment.
For example, the dominant white gene masks the expression of other genes, meaning a totally white cat could possess the genes for nearly any pattern or color. Recent genetic studies have helped determine the origins of some of the oldest recognized breeds. Concerning the domestic cat, it is perfectly designed for two prime functions—pest control and companionship—and people can select a cat according to which purpose is mainly desired.
Sight and “glowing eyes”
- Their sense of smell is crucial to sensing prey and evaluating food.
- Typically, cats walk or run by moving the front and back legs on each side together.
- One lineage appeared in Asia Minor as early as 6,400 years ago, dispersing northward and westward into Europe.
- The tail is part of the spine and generally contains an additional 20-some caudal vertebrae.
- Both lineages continued to breed with the African wildcat during their respective dispersals.
- These standards are usually drafted by breeders involved in establishing or promoting the breed and are approved by cat associations.
Only when a male cat has a rare mutation that gives him two XX chromosomes and one Y chromosome can he be tortoiseshell. The tabby pattern may not be expressed because of modifying genes. These standards are usually drafted by breeders involved in establishing or promoting the breed and are approved by cat associations. For example, such breeds as the Siberian and Norwegian Forest Cat developed long dense coats to protect themselves from the harsh winters in Russia and Norway. As cats spread around the world, pockets of cats adjusted to their unique environments and passed on their adaptations to their offspring. A cat breed is a group of related felines that share a conformation, meaning a similar physical appearance, or a common geographic region of origin.
Writers Théophile Gautier and Charles Baudelaire paid the cat homage, and in the 20th century Rudyard Kipling, Colette, and T.S. The cat is also a familiar figure in nursery rhymes, stories, and popular entertainment. (According to legend, maneki-neko was not a black cat; she was a calico.) Maneki-neko (“beckoning cat”) figurines, usually portrayed with one raised paw, are especially common in Japan. For example, in many Western countries, a black cat is considered bad luck, though the same cat in Japan is considered an omen of good fortune. Surprisingly, the cat is mentioned only once in the Bible, in the Letter of Jeremiah.
Black cats in particular have been tied to witches, and at times they were burned alive along with their supposed witch cohorts. The Cat-Book Poems, a document dating from the Ayutthayan period (1351–1767) in Ayudhya, Siam (now in Thailand), contains illustrations and descriptions of various cats. The Norse goddess Freyja was said to have a golden chariot pulled by two white longhaired cats, and the Egyptians revered a cat-headed goddess named Bastet. The earliest record of cats in Britain dates to about 936 ce, when Hywel Dda, prince of south-central Wales, enacted laws for their protection. In India cats were mentioned in Sanskrit writings about 100 bce, while the Arabs and the Japanese were not introduced to the cat until about 600 ce.
