Thats kind of what I was thinking because he was acting hungry just after a few days. I place a piece of tile in his enclosure that I put the mouse on and last night after his meal I hadnt taken the tile back out and he had eased up to it and laid his head on it like he was waiting on another meal.I guess I better order some rat pups tonite. No one around here has anything bigger than fuzzy mice that I can find without going live.
