I have a baby Sulcata that is just about 3 months old. I usually bring it outside on a daily basis for at least an hour to get some sunshine. It's usually pretty warm, sunny and humid here in SE Louisiana. Well, a cool front has come in and the highs are in the low to mid 60's. It has been a bit windy and overcast on some days, too. I haven't been bringing it outside because I'm pretty sure that the temps are too low and I don't want my tort to get sick. What is the lowest tolerable outdoor temperature for a baby Sully?
