That's much better, the temps. I seen you were from Maui. I been to Hawaii many times. Didn't know how it could be that cold day and night. Whew, you scared me there. Lol.Sorry, I may not have been clear. His house is at 80, not 67, and I don't really change it year round as the Upcountry Maui high and low temps only change about 10 - 15 degrees year round. No one has AC, not needed, and some have a fireplace for a chilly morning from late fall - early spring. I do get an alarm if the house gets too hot or too cold. Until now he spends most of his day in his yard, sometimes walking around, sometimes under a tree in the shade. And until now, goes into his house about 4 or 5. He's been happy, healthy and growing well.
Really only issue now I really need help with is if / when do I dig him out.
Tempting with food hasn't worked yet. It does sound from some of the responses that perhaps I just need to get use to burrow life.
Not sure you should let him stay there in the burrow. 67 is too cold for a sulcata. If he came out more often and went down just to cool off in the hottest part of the day but came up to bask it might be different. But I don't think he should be allowed in that cool of temps. Wait and see what Tom says. He has the most experience with Sulcatas then anyone else on this thread.
