Not so his behaviour. Though terrified of our labrador bitch (Seal), he shows no sign of running away -- standing firm all spit and hiss (and twice his normal size). We are gradually getting them used to each other. It is clear that Seal will eventually come out worse in the arrangements, and we know who the king of the household is destined to be.
Presently his dominion extends from the kitchen into the (warmer) dining room, with Seal carefully shunted sideways when he roams. This will have to do for the moment, though in a few days they will be allowed to mix (supervised). More news then.
