Reviewed public report
One report: conditional outcome
One traceable public report identifies this exact machine and litter and describes conditions or tradeoffs. That is useful real-world evidence, but one household is not enough to generalize.
Why this result
The displayed outcome follows the reviewed public evidence. The machine maker’s class-level rule remains visible below as a separate boundary.
Use this exact record
This is a practical reading guide for the evidence already shown on this page. It is not a controlled test protocol or a guarantee for another household.
Decision focus
The current report used this walnut litter in a mixture with Sustainably Yours and a longer cycle delay. It reports a fairly good result with occasional bottom sticking, but cannot prove how Naturally Fresh performs alone.
First-use check
Treat the saved result as evidence for a named mixture, not as a standalone test of Multi-Cat Walnut Shell.
If comparing with the report, record the second litter, mix ratio and cycle delay; otherwise your setup is materially different.
Inspect the globe bottom for occasional attached clumps and note whether manual release is needed.

Reviewed public evidence
These are traceable public use reports for this exact machine and product. They were reviewed for specificity and duplicates, but they are not PawExact tests.
An LR4 owner says a Naturally Fresh Multi-Cat Walnut and Sustainably Yours mixture works fairly well with a longer delay, but an occasional clump still sticks to the bottom and needs to be knocked free.
This record supports only its conditional outcome direction for the named pair and its coded observations: occasional or light sticking reported; no screening problem reported; no dust or sensor problem reported.
It cannot establish prevalence, causation, a product-wide winner, a health outcome, or the same result in another household, accessory setup, formula, or machine model.
What is not known
1 independent public report describes real use, but PawExact has not independently tested this pair. Machine guidance still controls the supported boundary, and individual homes may see different sensor, dust, sticking, saturation, or cleaning behavior.

These records are selected for a shared brand, material, weight class, or reported failure mode—not because PawExact has ranked them as substitutes.
