Has anyone out there got a cat as excitable as my Harry? He is a really loving and friendly cat, but whenever someone strokes him, he immediately rolls over to have his tummy rubbed and then promptly bites and chews and licks them. It is not done maliciously, he purrs all the time and never puts his claws out. He just loves to wrestle. Unfortunately he does have very sharp teeth and these tend to break the skin when trying to prise him off the arm he is wrestling with. Is this behaviour unusual or does it mean he is dominant or something else?
