He will be there two nights, and I gong to take the time to clean the room where he is very thoroughly. We have had to block him off form every surface as he is a jumper and got out of the room several times deosiute a four-foot gate. There is now a piece of cardboard at the door. The barrier is taller than I am, so I have to use a stool to get things into his room. I am ready for him to join the other cats, but we will have to do a gradual introduction as he is still very skittish. He may always be. He did warm up to younger dgd pretty quickly though.
