Why do cats trample on your lap? Your cat is on ypur lap and starts to press down, first with one front paw and then the other in a slow kneading or trampling motion. Sometimes the pricking of claws can be felt and the owner usually shoos the cat away. To find the meaning, it is necessary to watch kittens feeding at the nipple, with their tiny paws kneading at their mother's belly to stimulate the flow of milk. What is happening when an adult pet trmples on the lap of its owner is a place of infantile behavior. From the cat's point of view, this is a warm, friendly moment and its removal by a claw-picked owner is a classic example of the way in which interaction between humans and cats can lead to misunderstandings.
