Evil cat exorcism?

My cat is evil. He must be stopped. He attacks for fun and hates all other animals. I think he is plotting my demise right now. So should I look for a good exorcist....and are there pet exorcists?.....or should I just sleep with one eye open, or possibly swear my allegiance and be his lowly peon if he will just spare me the brutal attacks? Oh god here he comes...
