My tortoise wil not go to his new heated shelter on his own. If I put him in it he seems to like it and will spend the night. However, he won't go there on his own. I blocked off access to an area in my yard where he likes to sleep under a covered paddleboard. I thought given no choice he would go to the new shelter, but instead he went to sleep under my avocado tree. The other afternoon it was raining so I went to put him in the shelter thinking he would stay there. He warmed up and left for his favorite spot. I want to provide him with a warm and dry shelter, but he won't cooperate. Also, as he gets heavier I won't be able to move him. He was found wandering the street a year ago and nobody claimed him, so I kept him. Maybe he is not used to lying on a pig blanket and prefers roughing it.
