I have 5 cats. 3 are from the same litter. They've always been inside with a litterbox and 4 of the 5 cats have never had a problem. However, one of the males, Roo, likes to pee on me, my bed, the couch, in the hamper, and in the back door doorway...My fiance is telling me if he doesn't stop I have to get rid of him...but he's one of my babies! What do I do???
