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 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.
Ears
- Cats use a variety of sounds to communicate with other cats and with their human companions.
- However, the cat has relatively few taste receptors—only 473 compared with humans’ 9,000.
- Breed “standards” are written guidelines describing the attributes that make an ideal example of the breed.
- Maneki-neko (“beckoning cat”) figurines, usually portrayed with one raised paw, are especially common in Japan.
- 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.
- Adaptations have occurred with changes in prey, but the basic body type has stayed the same.
- This cat “radar” is vital to the cat’s ability to move about and hunt in low-light conditions.
It is also the smallest member of that family, which includes lions, tigers, and pumas.
Skin and hair
- Cats have no flat-crowned crushing teeth and therefore cannot chew their food; instead, they cut it up.
- The existence of these alternate forms allows for variety in cat conformation, color, and coat.
- For example, the mutation that causes the ears to fold in the Scottish Fold breed can also cause a bone and cartilage abnormality called osteochondrodysplasia.
- The construction of the shoulder joints permits the cat to turn its foreleg in almost any direction, allowing for quick turns when chasing prey.
- The paired gene copies may be different from each other and cause variations in characteristics.
- In addition, cats have a special sense best described as a cross between taste and smell.
- Each gene inhabits a particular site (locus) on a chromosome, and, because cats have two of each chromosome, they also have two copies of each gene.
As mentioned earlier, the cat family is commonly divided between cats that roar and cats that purr. Thousands of cat mummies have been discovered in Egypt, along with mouse mummies, presumably to provide food for the cats in the afterlife. Humans needed their grain protected from rodents, and cats needed a ready food source. When humans gave up living as hunter-gatherers and began relying on agriculture, cats were attracted to the rodents feeding on crops and stored grain. Although the animal was certainly a source of meat and pelts, a partnership of sorts eventually developed between humans and cats, one based on mutual need.
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.
For example, long hair in cats is a recessive trait; a cat must inherit the gene for long hair from both parents to have long hair. Cats use a variety of sounds to communicate with other cats and with their human companions. “Tomcats” (sexually mature males prone to fighting over mates) are not particular about the age, breed, or kinship of mating partners; they readily mate with related females.

In the center of the tongue, the papillae form backward-pointing hooks that rasp meat from the bones of prey and scoop up water when the cat drinks. The paw pads are also acutely sensitive and help the cat when grasping prey. The whiskers (vibrissae) are touch receptors that are vital to the cat’s hunting ability.
Cat (Felis catus), also called house cat or domestic cat, is a member of the family Felidae in the order Carnivora. Domestic cats have 19 pairs of chromosomes and, like humans, one pair of sex chromosomes determining their sex (two X chromosomes for females, one X and one Y chromosome for males). These genes determine the genetic makeup of the cat, called the genotype.
Cats (
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.
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.

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.
“Black,” “orange tabby,” “longhaired,” “shorthaired”—all are common categories by which cats are identified, advertised, and sought. The English legend of Dick spinmills casino promo code 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.
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.
Domestic cats are characterized by retractable claws, powerful bodies, acute senses, long tails, and specialized teeth adapted for hunting prey. For example, the mutation that causes the ears to fold in the Scottish Fold breed can also cause a bone and cartilage abnormality called osteochondrodysplasia. A gene at a particular locus on a chromosome may have more than one form, because genes can mutate, and these changes may be passed onto future generations.
