Before You Buy
Key Buying Factors
01
Clumping Ability
Hard clumps make scooping easy and prevent urine from pooling. We look for litters that form solid clumps that don't crumble.
02
Odor Control
Natural litters vary in how they neutralize ammonia. We evaluated each for how long it controls smells between cleanings.
03
Dust Levels
Low dust is crucial for cats and humans with respiratory issues. We assessed dust clouds when pouring and scooping.
04
Tracking
Some natural litters track more than others. We consider litter particle size and weight to minimize scatter outside the box.
05
Material Sustainability
We prioritize renewable, biodegradable materials like walnut shells, corn, and pine over non-renewable clay.
06
Multi-Cat Suitability
For homes with multiple cats, the litter must control odors and clump well despite heavier use. We test each in multi-cat conditions.
Living With It
Care, Cost and Maintenance
Scoop Daily
Remove clumps and solid waste at least once a day to control odors and keep the box clean.
Deep Clean Weekly
Empty the entire box, wash with mild soap and water, and refill with fresh litter every 1-2 weeks.
Maintain Depth
Keep litter 2-3 inches deep for proper clumping and absorption. Add fresh litter as needed to maintain depth.
Pro tip
When switching to a natural litter, mix it gradually with your cat's current litter over a week to avoid litter box aversion. We found that a slow transition increases acceptance.
Frequently asked questions
Is natural cat litter flushable?
Some natural litters are labeled flushable, but we recommend checking local regulations and your plumbing. Corn and walnut litters may be flushable in small amounts, but pine pellets should not be flushed.
How often should I change natural cat litter?
For clumping litters, scoop daily and do a full change every 2-3 weeks. For non-clumping pine pellets, replace the entire box weekly or when saturated.
Does natural litter track less than clay?
Tracking varies by material. Pine pellets track less due to their size, while lightweight corn litters may track more. We found walnut shell litters track moderately.
Is natural litter safe for kittens?
Yes, most natural litters are safe for kittens, but avoid pine pellets if your kitten tends to eat litter, as large pellets can cause blockages.
Which natural litter has the best odor control?
In our evaluation, walnut shell litters and corn-based litters performed best. The Naturally Fresh Walnut and World's Best litters both effectively neutralized ammonia odors for up to two weeks.
