Okay, here’s the deal: If you open up any brand of silica cat litter… there is indeed silica dust in there. I’m not talking about the pearly shapes… but at the bottom of the bag there is actual dust. Not nearly as much dust as clay litter… not even close. But it’s there. That’s the stuff that worries me, and it makes me wonder if dust breaks out of these pearls once in the litter box, too.
Thanks @lillycoyote , if that article is correct, then the litter is amorphous synthetic as you mention, which doesn’t cause this disease.
Thanks @Shooter12 , I didn’t realize there were other hazards.
The whole point of switching to this stuff was my cat sneezing too much, and I figured the clay and clumping clay caused too much dust. After the silicon stuff, i’ll try the newspaper pellets, but I bet that kind of litter is gonna stink unless changed often.
