I have no idea what to do. We keep his litter box clean and he poos and usually pees in no problem. We have a laminate floor and recently he has started sometimes peeing in the same spot - we've recently been away but had a Catsitter, but on coming back he (the cat!) had peed there again and the floor has started to rot. I'm at the end of my tether - I've tried bicarb, tin foil and various odour removers and he still does it. Anyone have any tips?
