We have a home made set up based on the one we bought with our first tortoise. It has a heat lamp and a uv one. We turn these off at night. They also have a covered area that is not heated. Our room heating is left on at night so the room doesn't drop too cold. I have a large tile in the heated section. We are looking into getting a rabbit run type enclosure for summer. Pepper has steadily put on weight and grown in the last 6 years. They both eat well now and are going to the toilet regularly.
