I give up! I’ve never had a kitten or a cat who played this tickle-my-belly-and-Peek-a-boo game. I’ve tried. They either just lie there and purr, or get up and walk away, or look at me like they wonder what’s the matter with the stupid human.
P.S.–Did you know most lizards will go to sleep, or into a kind of trance, if you rub their bellies?
