Our family has 9 cats. At one time we had as many as 11. Most are indoor and outdoor cats during the summer but in the winter they're all inside which means lots of litter usage. I have tried every kind of litter made and have found this brand the best for odor control which is our #1 concern. It clumps really well for the wet, and covers poo odor too. It is a bit more pricey than it's competitors, but well worth the money.
