California residents — Proposition 65

This product is tested against the Proposition 65 chemical list — no listed substances detected above safe-harbor levels. Certificate of Analysis available on request at hello@rootpurr.com.

A 12-pound monthly supply of our pea-fiber tofu litter. If you live in a small apartment without trash chute access, or you simply hate hauling litter, this is your friend. Designed to disperse in municipal sewer systems (not recommended for septic systems without a professional sewer-line assessment). Some municipalities advise against flushing cat waste due to T. gondii concerns, so check your local rules. Slightly slower-clumping than cassava (30 seconds vs 3) but fully biodegradable.

Less mess. More purrs.

Flushability disclaimer · Read before flushing

Our Tofu Formula is designed for municipal sewer systems only. NOT septic-safe without a professional sewer-line assessment. Some municipalities (parts of CA, WA, OR, IL) prohibit flushing cat waste regardless of litter type due to Toxoplasma gondii concerns — check your local sewer code first. Flush one clump at a time, never the whole tray. Cassava-based formulas (House Blend, Cassava Formula) are not flushable under any circumstances.

Substantiation:Biodegradation testing per ASTM D6400 is in progress — results expected Q3 2026. Until then, “biodegradable” on our pages describes the plant-fiber raw material, not a certified end-of-life behavior claim. For our current third-party lab results, see the Lab Testing page.
