Average directional index

The anatomy of the domestic cat is similar to that of other average directional index of the genus Felis. Cats have highly specialized teeth for the killing of prey and the tearing of meat. The premolar and first molar, together the carnassial pair are located on each side of the mouth. These teeth efficiently function to shear meat like a pair of scissors.

The cat’s tongue has sharp spines, or papillae, useful for retaining and ripping flesh from a carcass. These papillae are small backward-facing hooks that contain keratin which also assist in their grooming. The cat’s oral structures provide for a variety of vocalizations used for communication, including meowing, purring, hissing, growling, squeaking, chirping, clicking, and grunting. For the plant species, see Cat’s ear.

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. Cats are highly territorial and secreting odors plays a major role in cat communication. The nose helps cats to identify territories, other cats and mates, to locate food, and for various other causes. A cat’s sense of smell is believed to be about fourteen times stronger than that of humans. They walk directly on their toes, with the bones of their feet making up the lower part of the visible leg. All cats are capable of walking very precisely.

This trait is shared with camels and giraffes. As a walk speeds up into a trot, a cat’s gait will change to be a “diagonal” gait, similar to that of most other mammals: the diagonally opposite hind and forelegs will move simultaneously. For the superhero, see Cat Claw. For the plant species, see Cat’s claw. Like nearly all members of the family Felidae, cats have retractable claws. In their normal, relaxed position, the claws are sheathed with the skin and fur around the toe pads. Most cats have a total of 18 digits and claws.

The dewclaw is located high on the foreleg, is not in contact with the ground and is non-weight bearing. Some cats can have more than 18 digits, due to a common mutation called polydactyly or polydactylism, which can result in five to seven toes per paw. The normal body temperature of a cat is between 38. This is also an advantage for veterinary purposes, as it simplifies injections.
