This litter worked great until our two cats passed away and we got a 6 month old and 3 month kitten. Although the litter worked for odor control with kittens, I began going through double the amount of litter because the kittens would seek and destroy all the clumps. It required me to empty the entire box of litter each week to get rid of the smell from the broken clumps. I tried other stiffer clumping litters and the kittens hated them and wouldn’t cover their poop. I went back to Catspot after the youngest turned a year old. One kitten turned out to be part Maine Coon so we had to get a second litter box. Life is back to CatSpot odor control litter bliss. They cover their litter, nothing is broken apart and my house smells like we have outdoor cats. I have been a customer for many years. My previous reviews reflect My ongoing love for this litter. Both my daughters use this litter and enjoy the odor free benefits.
