Why Do Cats Knead?

6. Returning Affection

A cat might purr and knead while being petted on his or her owner's lap. The cat is kneading to demonstrate affection. Kneading is the cat's way of 'petting' a person. This kneading can be painful as the cat's sharp claws dig into skin. Kneading increases in rate and strength in direct proportion to the cat's feelings of happiness and comfort. It is very important not to punish a cat for kneading. The cat does not know the behavior is wrong, and punishment can irrevocably damage the relationship between cat and owner.
