Documented sourcing
Food-grade cassava starch from certified suppliers in Vietnam and Guangxi. Each shipment ships with a starch-grade COA.
Where we can't claim yet
No “flushable” on cassava. No “100% dust-free.” ASTM D6400 biodegradability is still in progress, so we don't put it on the bag.
Which formula clumps the hardest?
Cassava Formula. Single-ingredient cassava starch produces the hardest clump in our line. House Blend clumps just as fast (~3 seconds) and is softer on paws because of the pea-fiber tofu blend.
Can Tofu Formula be flushed?
In most US municipal sewer systems, yes. Tofu Formula is designed for sewer-compatible disposal. Never flush into a septic system. Many cities also advise against flushing any cat waste because of Toxoplasma gondii, so check your local rules first.
Is Cassava Formula septic-safe?
No. Cassava Formula and House Blend should not be flushed at all. Their dense clumps can stress household plumbing even in plant-based form. Scoop to the trash.
Which formula tracks the least?
Tofu Formula tracks the least, followed closely by House Blend. All three are below 1% powder content per the third-party report, far lower tracking than typical clay litter.
Which formula is best for kittens?
Cassava Formula or Tofu Formula. Both have soft pellets and a single recognizable ingredient profile. Most veterinarians recommend non-clumping starter litter for kittens under 12 weeks; once your kitten reliably uses the box, transition to either via a 7-day blend.
What's the difference between cassava and tofu litter?
Cassava clumps in about 3 seconds and produces a harder clump but cannot be flushed. Tofu (pea-fiber) clumps in about 30 seconds, has a softer pellet, and is sewer-compatible in most US municipal systems. Cassava is made from a single ingredient; tofu uses pea fiber plus corn starch binder.
