Why does my cat knead with its paws?

Kneading, the rhythmic pushing of paws against a soft surface, begins in kittenhood. Nursing kittens knead around the mother to stimulate milk flow, and the behaviour persists into adulthood in most cats.

The leading explanation is that the association with comfort and security carries forward. An adult cat kneading a blanket, a cushion or your lap is generally displaying contentment, and it is frequently accompanied by purring, slow blinking and a relaxed posture, all of which point the same way.

Scent marking contributes as well. Cats have scent glands in their paw pads, so kneading deposits their scent on the surface, marking it as familiar territory. This is why a cat may knead a particular chair or a specific person repeatedly.

A third factor is simply preparing a resting place, an echo of wild ancestors flattening grass or foliage before lying down. Cats frequently knead immediately before settling, which fits this reading.

Whether a cat kneads at all varies considerably between individuals, and a cat that does not knead is not unhappy. It is one of several ways contentment can present.

The practical nuisance is claws. Cats often extend them while kneading, which is uncomfortable on a lap. Punishing it is unhelpful, since the behaviour is instinctive and rooted in comfort. Keeping claws trimmed, or placing a folded blanket on your lap as a barrier, resolves it without discouraging the cat.

A sudden marked change in any long-standing behaviour, kneading included, is worth mentioning to a vet, since behavioural change can accompany discomfort.
