I need help. I have a 5 year old ruler of my world male cat. His whole attitude has changed since we moved in with my boyfriend over a year ago. Over the past year he started to jump on table tops, claw up the leather chairs, and even went poo on out bed. I know he loves my boyfriend because everytime he comes home from work my cat is all over him (rubbing his head on him, licking him). But when no one is home we find that he has destroyed something. He has never done any of this before. But I notice as time goes on he's doing something new (and not in a good way). I'm not sure what to do. Any ideals?
