is your cat jealous of devin? did the cat pee everywhere before or after he came into the picture? my one cat was extremely jealous when we got our Chihuahua and started doing that out of jealousy. we had a dog when our son was born who would tear up my sons clothes and toys but nothing else. we had a doggy door on the back sliding glass door and the dog would take my sons stuff outside and bury it but like i said ONLY my sons stuff. sadly we had to get rid of that dog.
