P.S. It also won't hurt to pre-scent the room, to get him interested in what's about to come... you can just lay it (frozen prey) on top of the cage for a while, and hopefully he'll start to poke around for it. I feed live, so usually I stick Delilah's mice in the critter keeper for a few hours, right next to her cage. I don't have to pre-scent with my others, since they'll eat anything at any time. Good luck!
