After 60 days of testing, Naturally Fresh surprised us. It out-clumps most clay litters. The walnut shells create hard clumps that survive rough scooping, and natural odor control is strong. The downsides are premium pricing at $0.96 per pound and the dark brown color that makes waste harder to spot. Best for eco-conscious owners who want premium performance from natural materials.
You want the best natural clumping performance, care about sustainability, or need harder clumps than most clay provides.
You're on a budget, need light-colored litter for health monitoring, or want the most economical option.

The clumps are rock-hard and survive rough scooping. Better than most natural litters and most clay litters.

The Walnut Shell Surprise
We expected Naturally Fresh to be "good for natural litter." We didn't expect it to out-clump most clay litters.
The walnut shell granules create hard clumps, denser and more durable than typical clay. It's the natural litter that clumps like premium clay.
♻️ Sustainable Byproduct
Naturally Fresh uses walnut shells left over from food processing. No trees cut, no mining, no farmland set aside for litter. The ultimate upcycled product.
Performance Results
The Dark Side (Literally)
The dark brown color makes waste hard to see. You'll hunt for clumps more than with light litters. That is the trade-off for the performance.
Who Should Buy Naturally Fresh?
✅ Perfect For:
- Hard clumps from a natural litter
- Eco-conscious buyers
- Sustainability advocates
- Natural odor control seekers
- Those wanting clay alternatives
❌ Not For:
- Budget buyers
- Health monitoring (dark color)
- White or light cat owners (staining)
- Anyone who needs flushable litter
Final Verdict
Naturally Fresh surprised us. It out-clumps most clay litters while being natural and sustainable.
The dark color is annoying, but the performance justifies the premium for eco-conscious buyers who want hard clumps.

Questions people ask
Does Naturally Fresh really clump better than clay?
In our testing, Naturally Fresh clumped surprisingly well: 89% of clumps survived drop tests. That is better than budget clay like Super Scoop (64%) and close to Dr. Elsey's premium clay (98%). The walnut shells create hard, dense clumps that hold together through rough scooping. If clump hardness is your priority, this natural litter beats most clay options.
Is walnut litter safe for cats?
Yes, Naturally Fresh is safe for cats. Walnut shells are a food byproduct from walnut processing and are non-toxic. The shells are cleaned and processed into granules. Walnut allergies in cats are very rare. If your cat has a known nut allergy, talk to your vet, but for almost every cat, walnut litter is safe.
Does the dark color make scooping harder?
Yes, the dark brown color is the main drawback. Waste doesn't contrast as clearly as with light-colored litters like Sustainably Yours or PrettyLitter. You'll need to look more carefully when scooping. The trade-off is worth it for the clumping, but health monitoring visibility suffers.
Does walnut litter control odor well?
Walnut shells absorb odor naturally. In our testing, Naturally Fresh controlled ammonia odor for 5-6 days, which is strong for a natural litter. The walnut scent itself is subtle and pleasant. For stronger odor control an activated carbon deodorizer additive still helps, but the walnut does real work on its own.
Can I flush Naturally Fresh?
No. Naturally Fresh is biodegradable but not flushable, so used litter belongs in the trash or in compost where local rules allow. If you need a flushable option, World's Best Cat Litter breaks down in water and is made for it.
Will walnut litter stain my cat's paws?
Naturally Fresh can temporarily tint white or light-colored paws slightly brown. This is harmless and washes off with normal grooming or a damp cloth. It doesn't stain permanently. If you have a white cat and this bothers you, pick a lighter-colored litter. Dark-colored cats show no visible staining.
