i have two cats...one is fairly new we just found him a few months ago and he was already litter trained. my other cat tho who we've had a couple of years now is an indoor outdoor cat. he's always been good since we found him. he goes to the door when he wants to go out and he always went outside instead of using a litterbox. now tho he seems to want to do it in a certain bedroom of the house its not just spraying either. he's even gone on my son's backpack. im really frustrated and dont know what to do. he's grown so its hard to get him to do something new. they're both getting neutered in a couple of days but i dont think this is gonna solve the problem. he's also been getting into alot of fights lately. his eye has been swollen for a over a week although its much better now. im really worried about him.
