He is a sulcata almost 25 years old, 160 pounds and has had a routine that he has followed for many years winter and summer. He hasn't come out of his house for 4 days something he has never before. He is alert, eyes look good and he defends his domain with vigor, which means he doesn't want me in the house. I'm worried about hydration more than anything else at the moment. His temperature settings are the same as they have been for years. I have 4 wireless temperature sending units in the house. He has always been sensitive to the barometric pressure but not for 4 days at a time.
