Well, since you’ve only just got him I would say a lot of roaming is to be expected. He will probably be quite stressed from the move and he’s in a new place with new smells so he will want to check everything out to make sure he is safe in there. My BP, Ramen, took about 5 days to calm down completely, and I mostly just tried to stay out of his way so I didn’t stress him more. Just keep an eye on your temperatures and humidity, to make sure that isn’t what is stressing him out. Also, are you regulating your heat sources with thermostats?
