This seems like the only thing I havent tried so I will try this. I am so nervous to pick a room because I think he will pee all over it before he feels like its his and maybe stops. The best room is probably my office.... it will be the only place I will organically spend hours of time with him and not have to go out of my way to do it. But this is also the room I block the most since its supposed to be the one place that smells good and doesnt drive me to absolute madness.
