I've found that there is little to no dust. When it's new, there's really no dust at all. But for me, by the time I change their litter in 2 weeks, there's a little bit of dust. I'm guessing it's because of the raking and breaking up of the litter itself. I'm happiest with this brand than I've been with any other brand I've tried. It keeps the odor controlled very well, the clumps are firm, and with this new brand even firmer.
There are only two rules at my house: House rule #1. Cats rule. House rule #2. See rule #1.
