why do cats do biscuits

Cats do "biscuits" or knead for several reasons rooted in their natural instincts and emotions. Firstly, kneading is an instinct from kittenhood when kittens knead their mother's teat to stimulate milk flow. As adult cats, they continue this behavior to express happiness, comfort, and security. Kneading is also a way for cats to mark their territory by releasing scent from glands in their paw pads. Additionally, cats knead to show affection and love towards their human companions and to help themselves relax by massaging soft surfaces. It is a behavior that conveys contentment and sometimes a request for attention or comfort.
