i have a leopard tortoise that's not older than two years old. I put him in this indoor enclosure with his heat lamp on, sense it's too cold outside. He has complete stop responding to any stimulation. I've had him sense Abril and everything has been fine. I'm so scared he is dead. His legs are kind of limp, but he has both of his front legs inside and i try to move them to see his eyes, but they won't move. Do they hibernate or his he dead. I'm so scared pls help me. I placed him in water for five mins and nothing.
