Natural cat litter covers a wide range of materials: walnut shells, wheat, tofu, wood, pea husks, corn, and bamboo. What connects them is what they don’t contain: mined clay, synthetic fragrances, or added chemicals.
The best natural cat litter controls odor, is easy for your cat to accept, and matches the way you want to clean the box, whether that means clumping walnut, low-tracking tofu, wheat, pea husk, or pine pellets.
The challenge is that natural litters behave very differently from each other. Walnut clumps like clay. Pine pellets break down into sawdust. Tofu clumps and can often be flushed. Choosing the wrong type for your routine creates more work, not less. This guide covers six options across the main natural litter types so you can match the material to how you actually clean.
Quick Picks
- Best Overall: Naturally Fresh Walnut Shell Cat Litter
- Best for Tracking: Tuft & Paw Really Great Tofu Cat Litter
- Best Wheat Litter: sWheat Scoop Multi-Cat Natural Wheat Litter
- Best Wood Litter: Feline Pine Original Cat Litter
- Best Pea-Based: Catit Go Natural Pea Husk Cat Litter
- Best for Transitioning: ARM & HAMMER Plant Power Cat Litter
How Natural Litters Differ from Each Other
This is the part most roundups skip, and it’s the most important thing to understand before buying.
Clumping natural litters (walnut, tofu, wheat, corn, pea) work similarly to clay. Urine forms a scoopable clump that you remove daily. The rest of the litter stays clean. These are the easiest transition from clay because the routine stays the same.
Pellet natural litters (pine, wood) work completely differently. The pellets absorb urine and break down into sawdust. You shake the box to let the sawdust fall through to a tray below, then empty the tray. Solid waste is scooped separately. It’s a different maintenance routine that some owners love and others struggle to adjust to.
Knowing which type you’re buying before you commit to a large bag makes a real difference.

Best Natural Cat Litter Reviews
Naturally Fresh Cat Litter Made from Walnut Shells
Why It Stands Out
Walnut shell litter is the least talked about natural option and one of the most consistently recommended. Ground walnut shells clump firmly, control odor well, and are the closest match to a clay-like routine among natural litters.
In daily use, owners report needing fewer full litter changes when they scoop daily and top up as needed. The darker color makes waste easy to spot for scooping. Some owners use it successfully in sifting and automatic litter box systems, though it’s worth checking your specific box’s guidance before buying in bulk.
Tracking is reduced compared to clay. The clumps hold together well during scooping, which leaves less contaminated litter behind.
Possible Downsides
The dark color surprises some cats and owners at first. Most cats adjust quickly, but a gradual transition helps if your cat is particular about change.
Best For: Anyone wanting a clumping natural litter that behaves more like clay while usually being lighter and lower-dust than many clay litters. The closest natural default for owners switching from bentonite. Also available in a quick-clumping formula if faster clump formation matters.
Tuft & Paw Really Great Cat Litter
Why It Stands Out
Tracking is the most common complaint about natural litters. Lighter granules stick to paws more easily than heavy clay. This tofu litter addresses that more directly than most, with tracking reduction as its primary claim and owner feedback consistently backing it up.
It’s made from soybean fiber, clumps firmly, and tends to produce very little dust. Some owners choose tofu litter when texture, dust, or tracking seem to be part of a litter box avoidance problem. The clumps can often be flushed in small amounts, but check your local plumbing rules and septic system guidance first. Never flush cat waste if your setup advises against it.
Possible Downsides
Tofu litter has a softer texture than clay. Some cats take time to accept it. A gradual transition over one to two weeks works better than a full swap. For more on how tofu litter works, this guide to tofu cat litter covers what to expect.
Best For: Owners whose main complaint with natural litter is too much tracking, and households where occasionally flushing small amounts of waste is practical.
sWheat Scoop Natural Wheat Multi-Cat Litter
Why It Stands Out
Wheat litter is one of the older plant-based options and sWheat Scoop is the most established brand in the category. It has a long track record compared with many newer plant-based litters, which makes it a safer starting point for people who want a proven wheat option.
The multi-cat formula is designed for heavier use. Clumping is strong and the routine is similar enough to clay that the switch doesn’t require learning a new system. Wheat contains natural enzymes that help neutralize odor rather than masking it.
Possible Downsides
Wheat litter can attract pantry moths if stored improperly. Keep the bag sealed and in a dry area. Some owners with grain allergies in the household prefer walnut or pine alternatives.
Best For: Multi-cat households wanting a clumping natural litter with a clay-like routine and a well-established track record. For more context, this guide to wheat cat litter covers how it compares to other natural types.
Feline Pine Original Cat Litter
Why It Stands Out
Pine litter works completely differently from every other option on this list. The pellets don’t clump. When urine hits them, they break down into sawdust. You shake the box to let sawdust fall through to a tray underneath, empty the tray, and scoop solid waste separately.
Pine pellets can be very effective for urine odor because wet pellets break down and move away from the dry surface in a sifting setup. The natural pine material handles ammonia without any added fragrance. Dust is very low because the pellets stay intact until they’re wet. Tracking is also significantly reduced since whole pellets are too large and heavy to stick to paws.
Possible Downsides
This system requires a sifting litter box or two-tray setup to work properly. Standard boxes make the sawdust harder to manage. Some cats find the pellet texture unfamiliar and need a longer transition than with fine-grain natural litters.
Best For: Owners willing to use a pellet-and-sifting routine who want strong odor control and minimal dust. This guide to using pine pellets for cat litter covers the full setup, and our best wood cat litter guide compares pine pellets against clumping wood fiber options side by side.
Catit Go Natural Pea Husk Clumping Cat Litter
Why It Stands Out
Pea husk litter is one of the newer plant-based options. Catit’s formula clumps firmly and tends to leave less wet residue behind than some softer plant-based litters.
The standout quality is that it’s genuinely unscented. Several owners who specifically needed a fragrance-free natural litter tried others that turned out to have a detectable scent despite their labeling, then found this one consistently delivered on the unscented promise. For cats and owners with any fragrance sensitivity, that distinction matters.
Possible Downsides
Pea husk litter is lighter than clay and tracks more easily than heavier natural options like walnut. A mat outside the box helps manage it.
Best For: Fragrance-sensitive homes and cats that have rejected litters with any detectable scent, even mild ones.
ARM & HAMMER Plant Power Plant-Based Clumping Cat Litter
Why It Stands Out
ARM & HAMMER is the most familiar name in the cat litter aisle, and Plant Power is their plant-based option. For owners who’ve always used ARM & HAMMER clay and want to move to natural without a completely unfamiliar product, this is the lowest-friction switch.
Owner feedback suggests it works well for people who want a plant-based litter but still prefer a clay-like scooping routine. Paw comfort and odor control come up often in owner accounts, and it has been reported working in high-use multi-cat households.
Possible Downsides
It doesn’t have the long track record of sWheat Scoop or Naturally Fresh. Some owners transitioning from ARM & HAMMER’s clay formulas find the clumping slightly different from what they’re used to.
Best For: Owners switching from ARM & HAMMER clay litter who want a plant-based formula without a steep adjustment curve.
What to Look for in a Natural Cat Litter
Match the type to your routine. Clumping natural litters work like clay. Pellet litters like pine require a sifting box or tray system. Knowing which you’re buying before committing saves a lot of frustration.
Cat acceptance varies more with natural litters. Cats that have used fine-grain clay their whole lives may resist coarser textures like pellets or walnut. A slow transition over one to two weeks works better than a full swap. Mix the new litter gradually into the existing one and let the cat adjust at its own pace.
Dust levels differ by material. Pine pellets and walnut shell litters are among the lowest-dust natural options. If low dust is the primary concern, this guide to the best low dust cat litter covers both natural and clay options side by side. For households where fragrance sensitivity is also a factor, our best hypoallergenic cat litter guide covers options that address both.
Flushability depends on your plumbing. Some natural litters are marketed as flushable, but local sewer systems and septic tanks vary. Always check local guidelines before flushing any litter, even those labeled flushable.
FAQ
Is natural cat litter better than clay?
It depends on what matters most to you. Natural litters are generally lower in dust, lighter to carry, and biodegradable. Walnut and wheat perform comparably to clay in daily use. Pine pellets work very differently and aren’t a direct substitute for anyone expecting a scoop-and-go routine.
Do cats accept natural litter easily?
Most adult cats adjust without major issues when the transition is gradual. The texture is the main hurdle. Tofu and wheat are often easier transitions than large pine pellets because the routine is closer to clumping clay. Cats used to fine clay granules may initially resist coarser materials. Mixing the new litter in slowly over one to two weeks gives most cats enough time to adapt.
Which natural cat litter has the best odor control?
Walnut and pine consistently come up as the strongest performers for odor control among natural options. Both work without synthetic fragrance, which matters for owners and cats with sensitivities.
Is natural cat litter safe for kittens?
For very young kittens, many people choose a non-clumping or plant-based litter while the kitten is still learning and may taste or play with litter. Avoid assuming any litter is risk-free if swallowed in large amounts. Ask your vet if you are unsure, especially for kittens under four months.
Can natural cat litter be used in an automatic litter box?
Some can and some can’t. Clumping natural litters like walnut and wheat work in many automatic systems. Pine pellets almost never work in automatic boxes because of the breakdown mechanism. Check your specific machine’s guidance before buying a large bag of any natural litter for an automatic system.
