I recently finished my sulcata's outdoor enclosure and he seems to really enjoy it. He has plenty of shaded areas to hide, but he just lays in the sun, its been in the mid to high 80's but in the sun it feels much hotter. So i guess my question is how long is it safe for him to lay in the sun, and if he wont move to the shade by himself should I bring him inside? Im afraid he will get heat stroke. I should also point out his previous owner kept him inside for 8 years so I am not sure if he really knows how to be a tortoise.
