My cat, Cooper is a 7 year old Male Calico. He has always been docile for the most part with the occasional burst of unexplained energy. But lately, he has been acting strangly. He will meow and rub against you for attention and when you pick him up he will purr and rub some more, and then out of the blue he will growl and hiss, but not try to escape or anything. He just sits with his rear on my chest, his front paws on my shoulder and growls and hisses for no apparent reason. This seems to happen more when my boyfriend is around. (We used to live together and now he just comes to stay the night a few times a week).
Another change is that about 2 months ago I got a kitten to keep Cooper company while I am at work since my boyfriend is around as much. They get along pretty well. They play and lick each other and cuddle on the couch and bed.
I was wondering is Cooper's sudden change in behavior is something to do with the recent changes in company or if it might be something health related.
Cooper is declawed and neutered, while Riley (the kitten) is neither. Also, I had to treat them both for fleas recently due to the fact that Riley was carrying when I brought him into the house. They both seem to be flee-free now as my boyfriend and I bathed them and treated the carpets and furniture, but I am also wondering if the fleas may have caused a change in behavior. By the way, while we were bathing Cooper he bit Stephen, but not me.
Do you think there is a fear of my boyfriend? Or could it be a health issue?
Sorry to ramble, I just keep thinking of things that might help distinguish the problem.
Thank you for your time and input,
