Kitten is 4 1/2 months now. Lately he is getting really bitey with me but only does it when he's trying to sleep on me. He will be all snuggly with me and keeps coming up right close to my chin and then tries to bite me on my chin or my neck. I keep telling him no and removing him and I thought he was starting to get the message. Tonight, just now, he was fast asleep on me for best part of an hour. I moved him slightly just to reach for something and he woke up a little bit, got up, rearranged himself and seemed like he was going back to sleep, then got back up again and bit me full on my lip! It bloody well hurt and I shouted 'NO' and threw him off me. He has made my lip bleed!
Why is he doing that? It's weird, it's almost like an affection thing but he's actually getting quite aggressive!
