Anyone ever keep a tortoise?

[PaulVerrall]

I have a Horsfield Tortoise, called Sherlock. He's about 8 now. I built him an enclosure outside. He's preping himself for hibernation now. We'll pop him in the garage for the winter soon.

Very nice!
Everywhere I read says if I keep it indoors it'll need a heat lamp and uv lamp. I understand the uv but why heat if most people keep it in the garden

We put the plastic label over the top to reflect heat and UV and that area of the garden has sun for a long part of the day. We had him on a table for 7 years but he has grown more, and been more active since he has been outside.
