[Thorsmomma]

I really am at a loss (again!). Thor keeps attacking our cat. This happens almost everyday, and sometimes twice a day. For no reason, he'll just go for the cat. I thought he was getting better, but obviously not. He just attacked our cat really bad and I pulled a huge chunk of fur out of Thor's mouth. It's like he is totally out of control. His jaw was just shaking...he does that jaw thing when he's playing to rough sometimes too. It's just like he has gone to another level or something...its crazy! When he attacks the cat he goes to time out, and before he goes to timeout I tell him NO, BAD BOY, and stare him in the eyes for a minute. Please help me!! I feel so bad for our poor cat. It's not fair. I really need some advise.
Thanks.
