I was told by another person he could be hibernating (I know it's called something different) but he's still pretty active at night. During the day he just hangs out under his tree. When I threw food in his cage Friday he didn't flick his tongue. I've had him since the third of February and have never seen his tongue. He's a good eater, but I'm worried about that. He doesn't even do it when he's feeding. He took down two mice Friday night, but when we put them in there he looked like he was having a seizure. He did the same thing last Friday as well. Ideas? Insights?
