So I've had my ball for about two weeks. When I first got him, naturally, he was curious and exploring his surroundings of his new home - testing out both cold and hot sides, going in the hides, drinking from his water bowl, climbing, ect. That was for maybe the first three days. He's eaten twice with no problems, and when I've handled him he's very friendly and active. But whenever he's put back in the cage, he goes right to the warm side's hide, curls up, and stays there. I figured this was normal since they're nocturnal, but every day since, I've seen no signs whatsoever that he even leaves or moves at night. I stay up pretty late these days, usually about til 2AM, and the lights in my room are off so he knows it's night (I turn them off at ten). But I never see him come out anymore!

Is this a problem? I don't think he should be sleeping all day and all night for days and days, should he? I guess I don't know 100% for sure that he's not moving, because I do sleep, but I see no evidence that he moved about and every time I look at him he's in the same position, curled in that hide. Any suggestions? Should I do something?
