This cat litter stands up best to heavy use by my four cats.
With four cats in my household, I have tried many types of litter. I liked the odor control of Tidy Cats Crystals, but my cats didn't like the texture of the crystal-only litter. I also didn't think they controlled urine odor very well. Then Tidy Cats came out with the Crystals Blend, and I have been very happy with it. It combines the best aspects of the crystals with a high-quality scooping/clumpable litter.The only negative I've seen is that it's a little sticky ... it clings to the cats' toes, and they track it out of the boxes. Putting in a mat under the boxes helps a lot with that. It's not too serious a problem. I don't think it outweighs the positives of controlling odor, clumping well and being attractive to my cats.
