I sorta' wondered about that since when you initially pour the stuff out of the bag and into their litter boxes it makes a cloud of "fines" which I certainly wouldn't want them (or me) breathing. Once it's in there though, I haven't seen any dust clouds or anything.

I've also seen some crazy stuff made of pine chips or something but it's silly expensive. Might be good though. Dunno.
