Sometimes he will eat 2 or 3 adult mice, I usually offer him whatever he will take. A lot of the time he will only eat one though, and skips a week once in a while. He has been a lot better about eating regularly as he is getting older, though.

He also seems to go off eating for 2-3 weeks either side of a shed, so every time he sheds he doesn't eat for 4 weeks or more.
