I've had my kitten since he was 7 weeks old, and he's 14 weeks today. I've tried to get him to stop this play biting/scratching but nothing seems to work. He has tons of toys, I've tried walking away/ignoring him and said NO firmly when he bites but all he does is run after me nipping and scarring up my legs! He's drawing blood from me and leaving painful scars and it's getting to the point where im very frustrated and I just don't know what to do anymore. 
Help GREATLY appreciated!!
