Tegus retreat to their burrows after being out during the day basking and foraging for food. Ask anyone that keeps them outside. Like Bert. Tegus bask outside their burrows; that's where the sun is. They are not moles that live underground.

I'm only telling you what has worked for me for at least 10 years years as well as other tegu keepers I've corresponded with who have kept them successfully for many years and bred them and kept their babies successfully until they breed themselves.

Do as you wish with your brand new tegu.

Over and out.
