Just to clarify further...I live in the High Desert...currently about 85. I bring them out if it's at least 75...at peak hours of the day...If they are kept inside...their habitats fluctuate between 80 and 100...their dens are about 75 with 10 - 20 % humidity. I've been here what? three days? and this is my favorite topic so far...Fife set some GREAT groundwork a few years back and it's AMAZING to see the variations people have developed since. Keep up the good work and Tom! Thanks for starting such a GREAT thread!
