Kneading is a common behavior displayed by cats, where they push their paws in a rhythmic motion against a soft surface, such as blankets, pillows, or even their owners' laps. This behavior resembles a gentle massaging or kneading motion. Kneading is a natural behavior for cats that begins when they are kittens. It is often associated with feelings of comfort, contentment, and relaxation. It is believed that the behavior stems from their instinctual need to stimulate milk flow from their mother while nursing. A cute animal progress bar for YouTube with Tabby Grey Cat Kneading.
