I use a radiant heat panel which dries it out on one side of the cage. At that point it does get a bit dusty and dry, but it isn't bad, and minimal misting can fix it if it bothers you. I didn't have that problem in cages using uths. It doesn't really stick to the animal at all (even when they bury themselves), but I find it messier in front opening cages. I only have one reptile right now, but every other reptile I've kept had a top opening cage. They sometimes "grab on to it" and it kind of goes everywhere but for the top opening cages you can just brush it off and it doesn't stick to you or them and falls back into the cage. In front opening cages it's a little harder and my boa frequently grabs on to it with her tail. Then it goes all over my carpet. Fortunately it's really easy to vacuum up and doesn't mess up the carpet at all, even if it's stepped on. So it's a little bit of a nuisance, but barely.
On a side note, Figment eats her meals on a pretty pink princess placemat.As soon as the placemat goes into her cage she lays her little face on it and waits for her dinner to appear. Then she eats on the placemat and goes back to bask on top of her warm hide when she's done. It's pretty much the cutest thing ever.
