Don't buy this product. Is it dust free? Yes, because when your cat pees in it, it clumps into a big wet clay like mess. I just went through 35 lbs of litter in 2 days. I do have multiple cats, but I used to use Special Kitty, 40 lb boxes that lasted me 2 weeks for the same amount of cats.
My hands were a mess by the time I got my litter boxes cleaned. I had disgusting, wet litter under my fingernails. I am going back to my old litter. It's cheaper and works better. I have never been so disappointed in a litter.
I'm just sorry I bought 5 tubs at a whopping $60.00 before I realized how crappy the litter was. What a waste of money!
