Ok, another concern of mine is that he's growing very sluggish and unresponsive.

Within the past couple days whenever I've tried to see him he's had to been touched before he moves.

I fed him yesterday, he ate the rat within 5 minutes. Then in evening he was exploring and drinking water and climbing.

And this morning, I found him out of his hide, and didn't move till I poked his nose.... I really really thought he was dead.
