This thread is really timely for us, because we have 3 cats and 4 litterboxes, and we just switched in the last two weeks or so to pine (the clumping kind, not the pellets kind) from FreshStep. The FS was giving me a sore throat and headaches, it was so bad. And the dust? Yeah, say no more. Now, I love the fresh natural-ness of the pine and the smell is much better, the cats have accepted it, and I feel it's very tidy (no urine smell). However, I do feel it is still dusty, at least as about 75% as dusty as FS, but, at this stage of the game, I'll take what I can get because I am just happy to have a natural option. PS It also is much lighter than the FS, which has been a nice side benefit!
