I just don't get it

[Hail3gh]

Last night my furnace crapped out. I did not know this until 6:30 this morning because my bedroom was still nice and warm. Obviously my lamps are not going to keep Olives Cage warm enough, so one would think he would stay on the side that is always warmer but no. I get up this morning get the wood stove going because it is 45 in my living room... Next thing I do is check on Olive, nowhere to be found.. An almost two foot lizard gone.... I built the Cage with two ways in one on each side heat lamps on both sides, I look on both still no. I start to think, Yep he was sitting on his favorite warm spot last night when I shutdown his day lamps, So I know I did not screw and lock him out... Well now I have to rip off the front walls and there he is, for the first time ever he burrowed in the middle of the cage equal distance from both lights in the coldest part of his cage. I put my hand in and he is already freaked out from the sounds of his house being ripped apart.... The next first he hisses at me a nice loud one then another... So I grab a shrimp out of the freezer quick thaw it and nothing no interest at all. Now I'm starting to worry, He feels cold... So I grab a pair of gloves and pull him out, he never tried to bite me or anything but boy was he mad... I put him over at the heat lamp and he is now nice and toasty and happy.... Explain to me this what the hell was he thinking! One would think its cold he would look for his safe spot his favorite spot but no he decides to try something new. The only thing I can think is maybe he was trying to hibernate
