I have never hibernated any of the many tortoises I've had. If you are not breeding, then there is no reason to hibernate...and I don'tn know about the breeding reason. When hibernation is so iffy, wouldn't you just have him up so you can watch him and play with him??? ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
