Hey - been out of touch. As you know from cham forum Luna is not doing well and I have been distracted. But beardie boy is doing great.
I have a rather elaborate setup for a baby (I was warned about all the poop cleaning!) so when he poops on a branch or corkbark I take it out and clean it. When I change his toweling, every couple days (b/c he doesn't poop on it much, I take him out and put him in a temporary house. I change the pt and then put everything back the way it was and make sure his basking sites are warm again then put him right onto his rock or branch. He doesn't have a problem with it. Frankly, he spends little time on the ground except getting to his feeding dish or going to sleep.
Not sure if this helps you at all...:-/ As for sand, I would certainly heed what more experienced keepers recommend
