I adopted a kitten about three and a half weeks ago. He's about 12/13 weeks old now. When I first brought him home, he never nipped, but he's starting to now. First it was only when I pet him and he wasn't in the mood to be petted. But now he'll cuddle up next to me and then start nipping my foot or my hand, without my even moving them first. I've been trying to say "No" loudly when he does it, and to either move him or move away myself to punish him by paying no attention to him, but it seems to be having little effect so far. I need kitten training advice!
