Right now in Phoenix he's doing just fine digging his burrow as it gets hotter. Occasionally, we get into the 30s and sometimes 20s on extreme nights in the winter. I tried looking up the low temperatures in Saharan Africa and couldn't find specific temperatures of where they live. All i can find is "they can stand surprisingly cold temperatures." I assume the Sahara has unusually cold nights as well. Will he be ok or should i put heating sources in his enclosure?
