Official boundary review
What the source supports—and where to stop
The conditional PETSNOWY statement for tofu and plant alternatives, applied without assuming that corn, walnut, tofu, pea, wheat, grass, cassava, and wood fiber share one result. Editorial review completed 2026-10-03; official source last verified 2026-10-03. This is not a PawExact test.
- Direct wording
- Plant alternatives may be compatible, with named cautionsPETSNOWY says tofu and plant-based alternatives may be compatible, but often form less compact clumps that might lead to moisture accumulation and require more frequent cleaning. The words may, often, and might are preserved because the source does not promise success or quantify a failure rate.
- How it applies
- The warning names the drawer, not a universal plant outcomeThe current visible FAQ locates possible moisture accumulation in the waste drawer and advises more frequent drawer emptying and cleaning for plant litter. That is not a measured plant-specific interval: the same page's general cat-count emptying examples are separate guidance, not a tofu or corn performance result. Record residue location and actual cadence.
- Exact-product record
- No plant SKU has an accepted SNOW+ observationThe current corn, cassava, walnut, tofu, pea, wheat, grass, and wood-fiber examples have zero accepted exact SNOW+ reports. Existing LR4 records, including mixture or fill-dependent reports, remain context for those LR4 households and do not establish SNOW+ behavior.
- Stop condition
- Stop before generalizing one plant constructionStop transferring a conclusion when the plant source, grain or pellet shape, exact formula, machine, fill, or cleaning interval differs or is unknown. The class warning can justify monitoring; it cannot produce a shared success rate, a universal cleaning schedule, or a winner among plant materials.
