We don't use any of the commercial cat litters. Instead, we use pine, cedar or aspen bedding litter. Our cats have been happily using this for years (at least 10 years now) and it makes us happy: no dust, no stray pellets all over the place to step on, nothing harmful in the litter and does not smell bad or like cat litter. You can see where they've peed (discolors the wood chips) and we just scoop it out and refreshen in between major cleanings.
