I’ve been using PrettyLitter for about four months in my multi-cat home. Dust is extremely low, and clumping is solid even with two cats using it daily. I feed Nature’s Domain wet food and Kirkland Signature dry food, and the litter keeps the box manageable. The color-changing aspect is interesting my cats’ urine has stayed healthy so far. I like that it’s non-toxic and seems gentle for declawed cats. My cats adapted almost instantly, and cleanup is super easy. Compared to World’s Best, I feel PrettyLitter gives better health monitoring without extra hassle.
