Finding the right cat litter can feel overwhelming — there are dozens of formulas on the market, from traditional clay to plant-based alternatives. But after analyzing expert testing from Wirecutter and Forbes, one thing is clear: the best litters control odor, clump tightly, produce minimal dust, and won’t track across your floors.
Here are the best cat litters for 2026, backed by real-world testing and thousands of cat owner reviews.
What Makes a Great Cat Litter?
- Odor control — The #1 priority. Great litter neutralizes ammonia and fecal odors for days.
- Clumping strength — Solid clumps are easier to scoop and keep the remaining litter clean.
- Low dust — Dust is bad for both you and your cat’s respiratory system.
- Minimal tracking — Larger granules stay in the box instead of spreading across your home.
- Unscented preferred — Vets recommend unscented litter. Cats have sensitive noses and may refuse scented formulas.
Top 5 Best Cat Litters (2026)
1. Dr. Elsey’s Ultra Unscented — Best Overall

Cat Litter Tips from the Experts
- Scoop daily — Minimum once per day. Twice is better for multi-cat households.
- Full change every 2-4 weeks — Don’t just top off. Dump everything and wash the box monthly.
- 2-3 inches deep — Too little and clumps stick to the bottom. Too much and you waste litter.
- One box per cat, plus one — The golden rule of litter boxes. 2 cats = 3 boxes.
- Skip the scented litter — If your litter box smells bad, scoop more often rather than masking with fragrance.
Final Verdict
Dr. Elsey’s Ultra is our top recommendation for virtually every cat owner. For eco-conscious pet parents, World’s Best Cat Litter is the best natural alternative. And for the ultimate litter setup, pair either with a Litter-Robot 4 for hands-free maintenance.
