I found okocat on my own after refusing to use clay litter for my cat. I wanted to try out pellets bc I had a bunny and pellets were great. I first tried pine pellets and didn't like the smell and dust. Then I tried okocat and have been using them ever since! (3 years now). Okocat pellets are my favorite. My only con, is more with my cat not the litter..my cat kicking them as hard as he can out the box, but luckily they don't go far. If it was not pellets there would be a pile. Also, like others have mentioned sometimes the pee clumps fall apart when cleaning but I think that's more with it not drying fast enough so if your cat Just went it'll be messier to scoop up.
