Situation.... built a beautiful outdoor enclosure for my sulcata to get him permanently outdoors. Haven't been able to keep him in it through the night because temps are still not quite warm enough yet until sun up. I want to be able to leave him in there all the time and not have to bring him in at night but my only problem is there's no electrical outlets on that side of the house so I don't have a way to heat the hide. Does anyone know of any alternate ways of heating the hide or anything battery powered that can be put out there? I've tried doing an internet search but don't really know what I'm looking for. Help!
