That sounds about right to me. If he doesn't normally sleep in the bedroom, now would be a good time to get him started. If everything he needs is there, then a lot of the pressure is off. It just takes a little time for a cat to get reaccustomed.

I've gone away for a week or two and left the cat in the house, when it's used to being out on the deck all day. On the other hand, she was always mad at me for a few hours when I came back ;)
