Corn and corn + cassava
World's Best formulas; Sustainably Yours Original
- Particle form
- Lightweight granules ranging from ordinary granular to a recorded large-granule formula; complete distributions are unknown.
- Clumping behavior
- All are recorded as clumping, but the available exact reports and mixture recipes belong to LR4.
- Machine boundary
- LR5's plant-filtering warning applies regardless of an LR4 good, poor, or mixture result.
- Exact evidence
- No accepted exact LR5 report for these products. Every LR5 relationship remains Estimated.
Walnut shell
Naturally Fresh Multi-Cat
- Particle form
- Lightweight granules with no complete recorded size distribution.
- Clumping behavior
- Recorded as clumping; the accepted conditional use record is mixture-confounded and tied to LR4.
- Machine boundary
- LR4 evidence cannot establish LR5 screen return, clump release, or fill sensitivity.
- Exact evidence
- No accepted exact LR5 report; the current product row is a class-rule Estimate.
Tofu and pea husk
Tuft + Paw Really Great; Catit Go Natural
- Particle form
- Lightweight pellet or pellet-like constructions; representative diameter and length are not recorded.
- Clumping behavior
- Both are recorded as clumping, but only the tofu SKU has an accepted report and it is for LR4.
- Machine boundary
- Particle form must be checked against LR5's screen; one tofu observation cannot transfer to pea husk.
- Exact evidence
- No accepted exact LR5 report for either product, and no LR5 fill threshold has been established.
Wheat and grass
sWheat Scoop Multi-Cat; SmartCat All Natural Clumping Grass
- Particle form
- Lightweight granules; shared marketing language does not establish shared grain geometry.
- Clumping behavior
- Both are recorded as clumping with no exact LR5 observation.
- Machine boundary
- Clumping alone does not move a plant formula into LR5's preferred standard-weight clay class.
- Exact evidence
- Both rows remain Estimated with unknown screen return, release, and long-term moisture behavior.
Wood fiber
Ökocat Original Premium Clumping Natural Wood
- Particle form
- Lightweight fiber granules, distinct from absorbent wood pellets.
- Clumping behavior
- Recorded as clumping, but strength and fragmentation in LR5 are unobserved.
- Machine boundary
- The plant-screening warning still applies even though the exact non-clumping pellet exclusion is not the same construction.
- Exact evidence
- No accepted exact LR5 report; construction classification does not supply an observed outcome.
Non-clumping controls
Fresh News paper; Feline Pine
- Particle form
- Paper crumble and pellet-or-shaving constructions rather than clumping plant granules.
- Clumping behavior
- Both are recorded as non-clumping and cannot be grouped with clumping plant alternatives.
- Machine boundary
- LR5 separately excludes newspaper-based, absorbent wood-pellet, and strictly non-clumping litter.
- Exact evidence
- No accepted exact LR5 reports are required to keep the official class exclusion visible; failure frequency remains unknown.
