What does it mean when your cat stomps on you?

Every night when i lie in bed, my male cat walks in place on my legs for 20-30 minutes. What is he doing, and does he need a cat psychologist?

That means he loves you and he is trying to get comfortable. I assume you are referring to the "pawing" back and forth action that cats often do. This is something that cats do to their mother's bellies when they are nursing. When they do that it means they are trying to find a nice soft place to take a long nap.

What the cat is doing stems from kttenhood. When they are feeding from the mother they do this to keep the milk flowing!
