That is cute...
I have that issue with Tank... if I have a cat on my lap being petted he will come over and poke the cat with his nose to make her leave. He knows that bugging me won't get him petted but if he gets the cat to leave then Mommy has her hands free for him. Most of the time, I ignore him after he does it, but sometimes I pet him... I need to get better at being more consistent.
