Updated April 2026·Experts: nytimes, WIRED

Best Overall

Dr. Elsey's Ultra Unscented Clumping Cat Litter

$20-$35

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.

What holds up

  • 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

What to know

  • Heavier than corn or tofu-based litters, harder to carry
  • Clay is not biodegradable or flushable
  • Can track fine particles outside the box
What people say
Its clumps held together almost as well as Dr. Elsey's Ultra's and better than Arm & Hammer Super Scoop's.

Best Natural/Eco-Friendly

World's Best Cat Litter Multiple Cat Unscented

$25-$45

World's Best is the litter I'd recommend to anyone who wants to go natural without sacrificing clumping performance. The odor control isn't quite clay-level, but for 4 cats it genuinely lasts, Reddit owners with big households swear by it.

What holds up

  • Flushable and biodegradable, made from whole kernel corn
  • Strong clumps that hold together well during scooping
  • Very low dust production in testing
  • A 27 lb bag lasts ~5 weeks even in a 4-cat household per Reddit users

What to know

  • Odor control not as strong as clay litter
  • More expensive per pound than clay options
  • Corn base may attract insects in some climates
What people say
My vote is for the Worlds Best cat litter. I have 4 cats and a 27 lb. bag lasts about 5 weeks. We scoop it once a day and it really works well.

Best Scented/Baking Soda Formula

Arm & Hammer Super Scoop Clumping Litter

$15-$28

Arm & Hammer Super Scoop is the practical everyday choice, it's widely available, affordable, and the box design alone makes it less of a chore to deal with. Clumps aren't as rock-solid as Dr. Elsey's, but for most single-cat homes it's more than enough.

What holds up

  • Cardboard box with plastic handle is easier to pour and store than bags
  • Baking soda formula provides strong scent neutralization
  • Widely available in grocery and big-box stores
  • Competitive price point for clay litter

What to know

  • Clumps are softer and more prone to breaking than Dr. Elsey's Ultra
  • Scented formula may irritate sensitive cats or owners
  • Higher dust output compared to Dr. Elsey's and World's Best in testing
What people say
This litter comes in a cardboard box with a plastic handle, so it's easier to pour and to store than Dr. Elsey's Ultra and World's Best Cat Litter.

The Litter-Robot 4 is the best automatic litter box on the market, and it only works well with quality clumping litter, don't cheap out here or you'll be cleaning the globe constantly.

What holds up

  • Clumping clay and bentonite litters work seamlessly with automatic box mechanisms
  • Reduces how often you need to interact with waste
  • Spacious Litter-Robot 4 globe accommodates most litter types
  • App connectivity lets you monitor litter levels and usage

What to know

  • Litter-Robot 4 itself costs $500+, making this a premium setup
  • Some litter types (tofu, long-grain) not recommended for automatic boxes

What people say
No automatic litter box is perfect, but the Litter-Robot 4 gets a lot right. It's spacious, reliable, and repairable. And it's easy to clean and customize.

Best Litter Mat (Accessory)

Gorilla Grip Cat Litter Trapping Mat

$20-$35

No litter is perfect at staying in the box, the Gorilla Grip mat is the cheapest, most effective fix for tracking. Buy it alongside whatever litter you choose.

What holds up

  • Coil design traps fine-grain litter better than ribbed or flat mats
  • Soft enough that cats don't avoid stepping on it
  • Works with all litter types including clay and corn
  • Easy to shake out or vacuum clean

What to know

  • Not ideal for sticky messes like vomit, silicone mats clean easier for that
  • Coils can be harder to deep-clean than flat mats
  • Doesn't eliminate tracking entirely, just reduces it
What people say
The Gorilla Grip Cat Litter Trapping Mat traps fine-grain scattered litter well, and it's more comfortable for cat paws than most other mats we tested.
