Hello, after months of research and consideration "Santa" brought our family a yearling Russian Tortoise. He is beautiful and is captivity bred and showed a lot of personality from the day we got him. Mid January he seemed to slow down a lot and would hide and burrow. I honestly think we had his habitat too warm, now we are measuring the temperature in there much better and we maintain about 80-85 degrees with his light on and about 78 when the heat pad is on at night. He has the proper lighting and substrate. We didn't mess with him too much the last six weeks, just made food available, would mist the substrate, and we took him to the vet where he got a clean bill of health. My concern is he is still not doing much. He does not appear to be eating and when he is moving around ( once evey couple days ) he is not opening his eyes. Should I be concerned? Is he hibernating? I have not noticed any bowel movements. I have read several books on the Russian tortoise and it's care but get conflicting information. I would appreciate any advice! We love Hoagy and want him to be a happy healthy guy!
