Why Do Cats Knead? The Science of the "Making Biscuits"
If you've ever had a cat curl up on your lap and start rhythmically pressing its paws into a blanket (or you), you've witnessed one of the most beloved feline behaviors: kneading, affectionately nicknamed "making biscuits."
It starts in kittenhood. Nursing kittens knead their mother's belly to stimulate milk flow. The motion is instinctive and gets wired in early, which is why adult cats keep doing it long after they've stopped nursing.
It's a comfort behavior. Kneading is strongly associated with contentment. A cat kneading on your lap while purring is basically saying "I feel safe here."
It's also territorial. Cats have scent glands in their paw pads, so kneading can double as a way of marking their favorite spots (and people) as their own.
So the next time your cat starts giving your leg an impromptu bread massage, know that it's a mix of nostalgia, comfort, and a tiny bit of "this is mine now."
