So I use SmartCat All Natural Clumping Litter. Which from research seems like one of the best kind of litters out there. I chose it because it's just grass, clumps really well, and has relatively low dust. The thing is my one kitten digs forever in the litter box, and I fear that she may be getting some dust into her ear. Because the litter is so light, she frequently gets some onto her fur and face. So anyone got any better litters?
