Best Cat Litter
Researched & compared
Cats are conservative about litter: most prefer a fine, soft, unscented substrate, and heavy perfume is added for humans rather than for them. If your cat is avoiding the box, litter is one lever — but box count, size, depth, hood and location matter just as much, and a sudden change in toilet habits is a reason to call a vet before buying anything.
Start here
- The rule of thumb is one box per cat plus one, in separate locations rather than lined up in a row.
- Most cats prefer an uncovered box that is larger than the ones sold as standard — roughly one and a half times the cat's body length.
- Scoop daily. No litter on the market outperforms scooping, and odor complaints are usually a scooping-frequency problem.
- Transition litter by mixing the new into the old over a week or two. An abrupt swap is a common cause of box refusal.
- Change one variable at a time, or you will never know which change fixed it.

What to know about cat litter
Clumping strength, dust level, odor control, and tracking — the four things owners actually notice, compared on what manufacturers publish and what buyers consistently report. Clay clumping litter is still the default because it clumps hard and scoops clean; the costs are weight, dust, and a mining footprint. Silica crystals control odor well and track badly. Plant-based litters — corn, wheat, walnut, paper, tofu — are lighter to carry and sometimes flushable, but clump strength varies enormously between brands. Cats are conservative about litter: most prefer a fine, soft, unscented substrate, and heavy perfume is added for humans, not for them. If your cat is avoiding the box, litter is one lever, but box count, size, depth, hood, and location matter just as much — and a sudden change in toilet habits is a reason to call a vet before buying anything. Change one variable at a time, and transition by mixing new litter into the old.
Cat Litter questions owners ask
How many litter boxes do I need?
One per cat plus one, placed in different rooms rather than side by side — two boxes in the same corner function as one resource to a cat that is being guarded away from it. In a multi-level home, put at least one on each floor.
How often should I change cat litter?
Scoop at least once a day, every day. With a good clumping litter and daily scooping, a full change and box wash every two to four weeks is typical for one cat, and more often for a shared box. Non-clumping litter needs a complete change far more frequently, usually about twice a week.
What is the best litter for odor control?
A hard-clumping unscented clay litter, scooped daily, outperforms most heavily perfumed options, because a clump you can remove intact takes the odor out of the house instead of masking it. Silica crystals control odor well but track badly. Whatever you choose, scooping frequency does more work than the product does.
How do I switch my cat to a new litter?
Mix a small amount of the new litter into the old and increase the proportion over one to two weeks. If your cat hesitates, back off to the last mix it accepted and move more slowly. Offering a second box with the new litter alongside the original one also works, and lets the cat choose.
