Thank you LR!
It is quite private, and he doesn't mind going past the dogs if he needs to. He is quite comfortable around them anyhow, and rather fond of my little female Rottweiler.
He is between 4 & 5 years old - I'm thinking you are right; he just doesn't like the change. I guess I'll keep another in the basement...well maybe I'll put a slightly "used" one in the new place too! Maybe that will give him a clue.
