Pros

  • Unscented formula avoids added fragrance
  • Clumps for straightforward daily scooping

Performance notes

It's unscented, so it doesn't add fragrance to mask odor. Odor control comes mainly from the clumping action and how often the box is scooped.

Does it clump?

Yes, it's a clumping clay formula, meaning it firms into solid clumps when wet so they can be scooped out rather than needing a complete box change.

How big is the bag?

It comes in a 40 lb bag, which is a bulk size suited to multi-cat households or anyone who wants to restock less often.
