I bought a box of Simplicity Plus at Costco and so far I prefer it to the Tidy Cats which I've been using for 15 years and more.

It costs less, and works well, seems to have less dust.

Only drawback I've found, is that it comes in a 44 pound box. Oof! As most of my cat litter boxes are down cellar, getting the boxes down there is going to be a challenge.

I wondered if anyone else has used it?
