Clumps well that's about it!
My roommate has 2 cats and normally uses Tidy Cats but decided to try something with a little bit more odor fighting power. It does change color and clump a lot better than the other stuff but it doesn't deodorize very well. Even when only one cats is using the box the smell still is stronger than it was with Tidy Cats. I'm always spraying air freshener. However, we also live in a small apartment so maybe if you have more room than it would work differently. I would save your money.
