He's in a small cage and the small cage is in the large cage. The glass one has a screen top and I located UVB there. I don't think it's a digital thermometer. I'll go get a digital one soon! he seemed really nervous last night but today he seems calm down a lot and he ate some crickets! good thing? =] I can move the small cage out of the large one just in case one of them might have virus.. but I live in a studio. so there's no separate room for me. so it doesnt matter right? if viruses can be airborne?
