Since I posted, he has sprayed twice, and overshot trying to use someone elses tray!! I have sussed it out though, it is trying to cover their scent with his, so I have stopped his access to the bathroom, used lots of Simple Solution (new foster coming on Wed) and then put him outside to see if that helped him get anything left out by scenting outside (someone has scented my car!!) - I dont mind the cat room as much, as there is very little carpet in there, and painted floor is easy to clean. The only advantage is he tends to do it in front of me, I have found very little when I haven't been there, so I can stop him and clean it asap. We have had fun with tea though, I bought them some raw turkey to try, and he was keen to try it, but struggling, so I chopped his up really small, then he got the hang of it and I left him chewing his way through a big piece cos he wasn't willing to wait for me to chop it!!
