Dr. Elsey's Ultra Unscented Clumping Cat Litter

Consistently top-ranked by Wirecutter for superior clumping and low dust. Hard, tight clumps make scooping easy and odor control beats most competitors.

$20-$35
Pros
  • Creates the strongest, hardest clumps of any tested litter
  • Minimal dust production in side-by-side testing
  • Excellent odor control compared to non-clay alternatives
  • Unscented formula ideal for sensitive cats and owners
Cons
  • Heavier than corn or tofu-based litters, harder to carry
  • Clay is not biodegradable or flushable
  • Can track fine particles outside the box
Why we recommend it

If you only try one litter, make it Dr. Elsey's Ultra. It outperformed every other clay litter in clumping strength and dust tests — the benchmark everything else gets measured against.

Wirecutter

Its clumps held together almost as well as Dr. Elsey's Ultra's and better than Arm & Hammer Super Scoop's.
