Cat kneading movements.
Kneading (also referred to as making biscuits[1] or cat-baking) is a commonly exhibited behavior frequently observed in domestic cats where, when a cat feels at ease, it may push out and pull in its front paws against a surface such as a piece of furniture or carpet, often alternating between right and left limbs. Each stroke is accompanied by a grasping motion of the claws as if the cat were kneading dough.
History[]
Many theories exist that explain why cats knead.[2] Kneading may have an origin going back to cats' wild ancestors who had to tread down grass or foliage to make a temporary nest in which to rest. Alternatively, the behavior may be a remnant of a newborn's kneading of the mother's teat to stimulate milk secretion.[3] Kneading may also be a form of communication between owner and feline: because of the action's maternal connection, the behavior may be a communication of affection towards the cat's human companion.[4]
Many cats purr while kneading. They also purr mostly when newborns, when feeding, or when trying to feed on their mother's teat. The common association between the two behaviors may indicate the origin of kneading as a remnant instinct. Some experts consider kneading to stimulate the cat and make it feel good, in the same manner as human stretching.
Action[]
The cat exerts firm downward pressure with its paw, opening its toes to expose its claws, then closes its claws as it lifts its paw. The process takes place with alternate paws at intervals of one to two seconds. They may do this while sitting on their owner's lap, which may prove painful if the cat is large or strong or has sharp claws (as the claws tend to dig into one's lap). Though cats will sit happily on a hard surface, they will only knead a soft or pliant surface, although some cats will reflexively "march" on hard surfaces instead of kneading them. A cat may appear irritated or surprised if it is disturbed while kneading.
In a garden where cats are to be found, sheltered areas can often reveal the "wild" results of kneading: round, cat-sized nests trodden into the long grass. Domestic cats also make "nests" out of cardboard boxes and other such things. They do this also by kneading with their claws out, in a manner such as to scratch and soften some of the material. This action is different in manner, body language, and intent from kneading when they are happy.
Cats knead soft objects. Cats may adopt a blanket and use it as a security blanket. This will include much kneading, purring, and suckling of the blanket. In some cases, cats have been observed to exhibit sexual movements, not unlike a dog "humping" a human leg, accompanying the kneading and suckling. Kittens who are taken away from their mothers before they are fully weaned may also develop a habit of kneading a human whom they have adopted as a maternal figure, and may also attempt suckling their ear, eye, nose, toe, hair, shirt, socks or fingers. Cats mainly do so as kittens, but sometimes the behavior continues into adult life.
