My cat is a 1 year old male. I got him when he was a week old because his mother left him and/or died so I've been the other "mother" he's ever known. He was going outside of his litter box on and off after I got him litter trained. He started going in his litter box all the time about 6 months ago. However, I went on vacation recently and left him for a week he's been going outside of the litter box (both urinating and pooping). He has chosen to go on the carpet in my dining room of all places. I've tried everything...taken him to the vet to make sure he wasn't sick, ignoring him, discipline, Odo-Ban & Oxyclean on the carpet, etc. HELP!!! Does anyone know of anything else I can try????
