I have used Elsey’s Ultra unscented litter for years but my recent batch has to be thrown out and replaced due to extreme dust. I mean...EXTREME. Scooping produces billowing visible clouds of dust engulfing me and making me cough! I wouldn‘t even have believed it was possible if I hadn’t experienced the extreme dust for myself. Ridiculous and totally unacceptable garbage. I wrote to Elsey and they gave an excuse about using a different part of their mines, and offered to refund my recent purchase. I will give Elsey one more chance since I’m a longtime user, but if I get more dust storm, I’m done with that litter.
