Cassava Cat Litter:
Manufacturer, Wholesale & Buyer's Guide
Cassava cat litter is a plant-based clumping litter made from food-grade cassava (tapioca) starch. Our flagship retail formula, RootPurr House Blend, blends 70% cassava with 30% pea-fiber tofu (no bentonite, no synthetic fragrance). It clumps in about 3 seconds, weighs roughly half what clay does, and we publish our third-party lab report so you can read the safety data yourself. This guide explains how it's manufactured, why testing matters for cassava, how it compares to pure tofu and traditional bentonite clay, and how US wholesalers and private-label buyers should specify it.
Quick answers
Is cassava cat litter safe for cats?
Yes, when it is properly processed and tested. Raw cassava naturally contains cyanogenic compounds, but milling and drying remove them, which is why testing matters. A sample of our cassava litter was third-party lab-tested: formaldehyde, aflatoxin B1, and Salmonella all came back non-detect. We publish that report in full on our Lab Testing page. With any cassava-litter brand, ask to see the actual test report.
Is cassava cat litter better than clay?
It depends on what “better” means. Cassava is about 50% lighter than clay, low-dust (our third-party test put powder content at 1%), and industrial-compostable. Clay is cheaper per pound and more familiar to long-time cat owners. For asthmatic households or apartments where weight matters, cassava wins; for the lowest sticker price, clay still wins.
1. What cassava cat litter actually is
Cassava cat litter is a clumping litter pressed from milled, food-grade cassava starch, the same starch used to make tapioca pearls, gluten-free baked goods, and a long list of FDA-recognized food ingredients. The starch absorbs liquid and forms a clump that can be scooped, bagged, and discarded.
Industry retail SKUs typically blend cassava starch with sodium bentonite (a naturally occurring clay) for structural strength. We do it differently. Our flagship Cassava Tofu Blend formula blends 70% cassava with 30% pea-fiber tofu. Fully plant-based, no bentonite, no synthetic fragrance. The cassava handles speed of clumping; the pea-fiber tofu softens the pellet and improves paw feel. Pure cassava (100% starch) is also available in our OEM line for premium private-label buyers willing to specify a custom binder system.
Buyers sometimes confuse cassava with tofu cat litter, but they are both plant-based, both biodegradable, and they look similar. They are not the same product. Tofu litter is made from pea fiber and corn starch, clumps slower (~30 seconds), and is genuinely flushable. Cassava clumps are too dense to flush.
2. How it's manufactured
Manufacturing happens in four stages: incoming starch QC, blending, pelletizing, and bagging. At our partner facility in Xingtai, Hebei, incoming cassava starch is inspected for moisture and quality before it's allowed onto the production floor.
- 1Incoming starch QC
Each shipment of cassava starch is sampled and inspected for moisture content (must be below 12%) and quality. Lots that fail are returned to the supplier and never reach pelletizing.
- 2Blending
Cassava starch and pea-fiber tofu are dosed at the spec ratio (70:30 default for our House Blend retail line; 50:50 to 80:20 custom on OEM orders). Activated carbon (0–3%), guar gum binder, and any optional scent are added at this stage. We do not blend with bentonite.
- 3Pelletizing
The blend is hydrated, extruded into 1.8–2.2 mm cylindrical pellets, surface-waxed for low tracking, then dried to moisture below 10%. A vibrating sieve removes fines.
- 4Bagging
Pellets are vacuum-sealed at source into kraft, PE, or zip pouch bags (4–25 lb), cartoned, palletized, and held for export inspection.
3. HCN safety: why testing matters
Raw cassava root contains naturally occurring cyanogenic glycosides (linamarin and lotaustralin). When the root is damaged or processed, an enzyme can release hydrogen cyanide (HCN). Properly milled, dried, and tested starch is safe; the cyanogens are destroyed during industrial processing. But skipping the verification step is a real safety risk for cats.
We are direct about this: the third-party report we currently publish covers formaldehyde, aflatoxin B1, Salmonella, ammonia deodorization, and powder content. It does not yet include an HCN figure. We will not print an HCN number until we hold a report that measures it. HCN is a named item on our testing-expansion roadmap, and B2B buyers are told exactly which tests are current and which are being added.
If you are sourcing cassava litter (from us or anyone), treat HCN testing as a required line item. Ask every manufacturer for a written HCN test method and a dated report on a finished-product sample. A supplier who cannot eventually produce one is a risk worth pricing in.
4. Dust and powder content
Two measurements describe litter dust. Powder (fines) content is the share of fine powder in the bag, a direct property of the litter. ASTM D6940 is the US standard test method for pour-out dust: a fixed weight is dropped from a fixed height in a sealed chamber and the airborne particulate is quantified.
The third-party report we publish measured powder content on a cassava sample at 1% (method T/HBPIA 01-2024). A formal ASTM D6940 comparison against a sodium-bentonite reference is on our testing-expansion roadmap; we have not published a D6940 figure and will not until that test is done. For any retail buyer marketing on “low-dust” or “dust-free” claims, a named method and a dated report is what holds up under FTC scrutiny.
5. Cassava : pea-fiber tofu ratios: what changes
Ratios below are cassava : pea-fiber tofu, not cassava : bentonite. We do not blend with bentonite. Higher cassava ratios mean faster clumping and lighter weight; higher pea-fiber ratios mean softer pellets and a higher portion of paw-friendly fiber.
| Cassava : tofu | Clumping speed | Pellet feel | Weight | Best for |
|---|---|---|---|---|
| 50:50 | Slower (~6 s) | Softest | Mid | Sensitive paws, kittens |
| 60:40 | Mid (~4 s) | Soft-mid | Mid-light | Premium retail balanced spec |
| 70:30 (default) | Fast (~3 s) | Mid | Light | Most US retail brands |
| 80:20 | Fastest (~2 s) | Firmer | Lightest | Asthma-focused, weight-sensitive shipping |
For first-time private-label buyers we recommend the 70:30 default, it's the spec our retail House Blend line is built on. Custom ratios add 7–10 days to lead time and require a 1 FCL minimum.
6. Cassava vs. tofu vs. clay
| House Blend (our 70:30 blend) | Tofu Formula (pure pea-fiber) | Sodium bentonite (clay) · reference, we do not supply | |
|---|---|---|---|
| Clumping speed | ~3 s | ~30 s | ~10 s |
| Flushable | No | Sewer-only · not septic | No |
| Weight (vs clay) | ~50% lighter | ~55% lighter | Baseline |
| Powder content | 1% · lab-tested | Low-dust pellet | High (clay dust) |
| Biodegradable | Industrial compost | Plant-fiber based* | No |
| Retail price/lb (USD) | $1.80–2.50 | $1.50–2.20 | $0.50–1.00 |
| MOQ (FCL, our factory) | 1 FCL | 1 FCL | 1 FCL |
US retail brands typically carry cassava + tofu as a 2-SKU plant-based assortment. Clay still dominates by volume but loses share each year to plant-based, particularly in the asthma-aware and apartment-dweller segments.

8. Frequently asked questions
What is cassava cat litter made of?+
Ground food-grade cassava starch, optionally blended with pea-fiber tofu, guar gum, and other plant-based binders. Our flagship House Blend is 70% cassava starch + 30% pea-fiber tofu, pressed into 1.8–2.2 mm pellets. The cassava handles absorption and clumping; the pea-fiber tofu adds softness and improves paw feel. We do not produce bentonite-based cat litter.
Why does cassava cat litter need HCN testing?+
Raw cassava root contains cyanogenic glycosides (linamarin and lotaustralin) that can release hydrogen cyanide during processing. Properly milled, dried, and tested starch is safe; skipping the test is a real safety risk. When you compare cassava-litter suppliers, ask each one for a written HCN test method and a dated report; the FAO/WHO food-grade limit for finished cassava products is 10 ppm.
How does cassava cat litter compare to tofu cat litter?+
Cassava clumps faster (3 seconds vs ~30 seconds for tofu) and produces denser, harder clumps. Tofu is designed for municipal sewer disposal (check local rules; some municipalities advise against flushing cat waste) and softer on cat paws. Both are plant-based and biodegradable. Most US retail brands carry both because customer preference splits roughly 60/40 cassava/tofu.
What's the standard cassava-to-pea-fiber-tofu ratio?+
70:30 is the most common retail ratio: fast clumping, strong structure, manageable cost. We can manufacture from 50:50 (most absorbent, softest clumps) up to 80:20 (lightest weight, fastest clumping but lower clump strength). Pure 100% cassava is possible but rarely chosen because clump durability suffers.
Can cassava cat litter be flushed?+
No. Cassava clumps are too dense to dissolve cleanly in plumbing, and even our cassava + pea-fiber tofu blend is not flushable in retail form. Flushing cassava-based litter risks plumbing clogs and is prohibited in most US municipal sewer codes. If flushability is a hard requirement, choose pure pea-fiber tofu cat litter instead.
What's the MOQ for cassava cat litter from your factory?+
1× 40HQ FCL (25 metric tons, ~4,500 cases at 12 lb / case, ~55,000 lb total) for custom-printed bags. 50 cases for already-printed RootPurr retail bags. LCL trial orders are possible for first-time buyers with a logistics surcharge.
