As it's dry it's going to be very dusty, but that part I use is all moistened when placed in the cage, and I keep it moist. I also use it for a chondro... who is never on the ground really, so there's nothing to stir up the dust that much. (except when he takes a crap the impact could, but i keep it so moist that little of an impact wouldnt do anything to it.) Also, since snakes shed the skin off their eye caps and such, how could there be a buildup in there? I can see how if this was used in a lizard cage or something it could but i think it'd be hard for a buildup in a chondro... but i'd like to see the data you were talking about.
