My kitten Beau is a sucker for petting and attention. But sometimes when petting he'll go into play mode and will attack fingers, hair, hands and even feet. Sometimes it's nibbles and soft paws and sometimes it's hard teeth and digging claws. He's already been neutered. I'm not sure how to train him to know that the way he plays is NOT fun sometimes without getting him scared of me or stopping him from playing with me altogether. I've tried walking away and ignoring him when he gets rough or shoving him off the bed. But he's not getting it or I'm not training him right. What to do?
