I've tried all kinds of litters. The silicon beads are the worst. I've tried the all natural kind made of sawdust pellets. They work okay. But you have to remove the solid waste or else it stinks up the place. It does a good job on the urine. As soon as the stuff turns to sawdust then you just replace it.

I now use Premium Scoopable Cat Litter. I get a 50 lb bag for $10. It's 99% dust free and my cats like it.

Good luck in your search for the perfect kitty litter.
