I had previously heard about PrettyLitter from a friend, and after scouring the reviews on the website, what actually convinced me to buy it was the claim that this litter is "dust-free," as I have asthma and had reactions to typical clumping litter.
The first thing I noticed when I opened the box (well, besides the fact that one of the bags of litter was slightly open and a bunch of litter had spilled out) and poured out the bags into the litter box was, "Wow, that's a lot of dust." Literally, plumes of dust smoking up into the air. But I disregarded it and thought maybe it was just settling after being poured.
That night, when I went to shovel out the poop, the first contact with the litter brought huge clouds of dust billowing up. With each shovel, the cloud became thicker and thicker, and within a minute I was wheezing and having a cough attack.
The next day, I threw the litter out and stuck with my usual crystal litter.
I don't know how this litter has gotten solely 4-5 star reviews or how cat owners have found a way to even get past the sheer amount of sandy dust that gets inhaled and envelops your entire face. Granted, my kittens did immediately take to it. But that might not be such a good thing considering they're inhaling just as much dust as I am, if not more, whenever they use it.
I'm disappointed and slightly repulsed by how they could make the "dust-free" claim, which is completely untrue.
Bottom Line: No, I would not recommend this to a friend
