Read my posts under the Fatties and leos thread a bit down from you and you'll see what my methods are.. I keep a general humidity of at least 60-70%.. usually more like 80 percent. They're thin skinned, they dehydrate easily and there is no reason humidity should be so low as most people keep it. Desert does not =no humidity. The animals find the places where humidity is.. and practically live there during the day.
