Naturally Fresh Walnut Review
Last tested Last updated
Our Quick Verdict
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.
Worth it if: You want the best natural clumping performance, care about sustainability, or need harder clumps than most clay provides.
Skip it if: You're on a budget, need light-colored litter for health monitoring, or want the most economical option.

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
Clumping (8.9/10) - Hard for natural litter
Drop Test Surprise:
| Litter | Clumps Intact |
|---|---|
| Dr. Elsey's Ultra (clay) | 98% |
| Naturally Fresh Walnut | 89% |
| World's Best Cat Litter (corn) | 76% |
The clumps are rock-hard and survive rough scooping. Better than most natural litters and most clay litters.
Odor Control (8.4/10) - Strong natural absorption
Walnut shells absorb odors naturally. We got 5-6 days of control with no additives. The walnut scent is subtle and pleasant.
Dust (8.1/10) - Low
Measured 0.13mg per pour. Much better than budget clay litters.
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.
Value Analysis
Running Cost (Single Cat):
- • $24.99 per 26 lbs bag
- • Lasts about 6 weeks
- • $0.54 per day
You're paying for premium natural performance
Who Should Buy Naturally Fresh?

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.

Bonus: Eliminate Existing Odor
Already dealing with litter box smell? Here's how to fix it fast.
Even the best litter like Naturally Fresh Walnut can't eliminate odor that's already built up in your litter box. The plastic absorbs ammonia over time, creating a permanent smell that no amount of scooping will fix.
Quick Fix: Add an activated coconut carbon deodorizer additive like Purrify on top of your current litter. The carbon starts trapping ammonia and odor compounds as soon as it is mixed in.
Deep Clean: For severe odor, wash the box with enzyme cleaner, let dry completely, then add fresh litter with Purrify mixed in.

Expert Recommendation
Make Naturally Fresh Walnut work even better
If odor is the main problem, pairing your base litter with Purrify activated coconut carbon additive is one of the cleanest upgrade paths in the review archive. It is an additive, not a litter, so cats can keep the texture they already prefer.
Add-On, Not Switch
Keep your current litter and layer in extra ammonia control instead of changing textures.
Ammonia Focus
Activated coconut-shell carbon targets the sharp urine smell without adding perfume.
