I suppose they could if they could reach it, but they are walking around on a thick layer of big flakes. The fine stuff is down on the bottom where they can't get to it.
X2...I just make sure the layer of big flakes is thick enough that they don't really get to the bottom layer of finer bedding...even when they decide they decide they need to scratch- scratch at the bedding for who knows what???LOL
Ok. I'll stick to my flakes then to be safe. Lol
