Once again...no help. 5 years I've been on this site and I can name 5 people that really care to help. Anyone else care to answer the question of should I really build an outdoor habitat for a 5 year old Sulcata that is very unhappy in the winter while living in NC? I just feel like it is too cold and what if the heating system failed.I reread the post, while we did go off topic a little bit and turn into a humidity debate. It look like a lot of his questions were answered, enclosure was addressed, diet was addressed. It looks like a lot of real help was offered. I hope everything works out for you and turbo.
