Which litter type should you choose?
If the dust bothers you, you should go for tofu and pine cat litter.
Tofu cat litter is likely the least dusty litter out there. It has all the benefits that traditional bentonite clumping litter provides, at the same time, it offers the added benefits of being non-dusty, nicer smelling, flushable, and friendlier to the environment.
Pine litter consists of small pine pellets, and it creates no dust. The downside of this litter is that its strong pine odor is disliked by many cats. Maybe your cat won’t mind the odor. Or, you can try switching to the new litter gradually, mixing it with the old one at first.
