Nothing that I'm aware of... We have a space heater in the room that keeps it at a consistent temperature, as well as the lights are on a timer, going off and on at the same time at night and in the morning, while their heat lamp stays on all night. I wonder if they didn't have the right humidity for one reason or another? I know it gets dry in our house, but my husband said he thought they had plenty of humidity... I got them both to eat one cricket a piece (and quite enthusiastically) but they seemed annoyed by additional crickets, though I suspect that might be due to the critter carrier they're in...

Oh, and we have one of those fog humidifiers, but we recently moved, so my husband hasn't set it up yet. And lord knows if I tried to, I'd never get the tubes positioned right.
