Pet Connection Q&A:Cat's tail will signal when to stop petting

We've been adopted by a cat, and he's earned his way from "stray we fed" to "our outside cat" to "sometimes inside" to "sleeps anywhere he wants in the house." He's usually affectionate and loves to purr, but now and then he just gets wound up and claws and bites us when we're petting him, just out of the blue. He never breaks skin with his teeth, but sometimes he hurts with his claws. It seems to be a game with him, but we need it to stop. Advice?
