So i've had my tortoise for about 2 years now (a russian tortoise, 8 yrs old), and it's about hibernation time now. i'm not sure what's happening, the temp. in the house is around 70 F (and higher around the heater he hangs around), his metabolism hasn't slowed down, he's not eating and wakes up randomly and wanders around in the daytime. what would i do? should i hibernate him or not? Any suggestions would be helpful
