on sleeping let him be a few days and see what he does. Your saying Pebbles is not sleeping so looks like you would have to make a decision, to brumate them both or put him in a seperate place. Also make sure before any brumation that they have enough weight on them, are not runts or thin. Some people don't brumate them young. But some do. Depends on their health. You can go to Will Wells site and read captive care, as far as steps to brumate, lot easier than typing it all out. Hope it helps ya somewhat Becca. Eve
