My juvie argentine red tegu started to go down for hibernation in mid december despite no change in temps/light/humidity, most of the time refusing food before she went down for real. It's been about seven months, and I check on her every few weeks- just peeking into the hide- and the upping of temperature or occasionally leaving food in the cage hasn't made any change. I'm beginning to get concerned, I know seven months is a pretty long hibernation period, is there anything I can do?
