The important usage detail: OPET also describes the lightly scented product as a booster to add to another clumping litter, so its instructions do not present it only as a stand-alone litter. Claims about odor control, dust and tracking come from the seller, while the small set of customer reviews offers mixed, subjective impressions.
What is OPET Corn & Cassava Cat Litter?
OPET identifies corn starch and cassava starch as the product’s base and lists a 7.3 kg (16 lb) package. The formula description does not establish that those are its only ingredients. OPET’s product page describes it as lightly scented and says it is made without added glue, preservatives, formaldehyde or harsh industrial additives. That is the manufacturer’s description, not an independent ingredient audit; the reviewed listings do not provide a complete ingredient panel.

OPET says the litter is designed to form tight, solid clumps for easier scooping and to stick less to the box and scoop. Those are product claims rather than results from a controlled test. The available sources do not establish how the clumps or sticking compare with other litters in matched conditions.

Is it meant to be a stand-alone litter or a booster?
OPET’s instructions describe this lightly scented product as a booster that can be added to other clumping litters. That guidance matters when assessing its role: using it as an additive is different from replacing all the litter in a box with it. The product is also marketed as cat litter, but the available instructions support booster use specifically; they do not give a tested ratio or establish that one use method performs better.

If following the manufacturer’s booster guidance, add it to a clumping litter as directed on the product packaging and follow the package instructions for routine litter care. Do not assume that the product dissolving in water means it is appropriate to flush; follow local disposal rules, as OPET advises.
What does OPET claim about odor, dust and tracking?
OPET USA advertises up to seven days of odor control, 99.9% dust-free performance, low tracking and biodegradability. The reviewed listing does not provide test methods or independent validation for those claims. Treat the duration, dust and environmental statements as seller advertising, not as a guarantee of what every home will experience or as independently verified health or disposal guidance. OPET USA’s listing also shows the 16 lb (7.3 kg) package.

What do customer reviews say about scent and performance?
Chewy displayed three customer reviews when accessed in 2026. Two favorable reports mention odor or clumping. The concerns include light tracking and one reviewer finding the scent stronger than expected, comparing it to laundry detergent. These are individual impressions from a very small, time-sensitive sample; they cannot establish typical results or how the product will suit a particular cat or household.

The available reviews do not establish whether scent perception varies by use method or home conditions.
Rank #3
- 26.4 LB (12 KG) LARGE BAG - FEWER BAG CHANGES: One 26.4 lb bag holds about the same as two 13.2 lb bags, so you swap bags roughly half as often and reorder less. Bulk size, priced by the pound rather than by the bag - see the per-pound price above.
- BUILT FOR MULTI-CAT HOMES: Hard, fast-forming clumps lock together and lift out in one solid piece, so the waste leaves the box and the clean litter stays in it. Sized for households running a box for two or more cats.
- PLANT-BASED CASSAVA AND CORN, NOT CLAY: Made from cassava and corn starch, not clay and not silica crystal. Lighter to carry and pour than clay of the same volume, and it scoops like a clumping litter you already know how to use.
- LOW DUST AND UNSCENTED: Zero added fragrance, so the box smells like nothing instead of like perfume. Low dust when you pour and when you scoop, which keeps the floor and the air around the litter box cleaner.
- 99.1% ODOR REMOVAL, CTI LAB-TESTED: Deodorization measured at 99.1% in third-party testing by CTI Cert (report WQIE), not an in-house number. Fast drying, hard clumping, and no added fragrance. Canadian brand, developed in Toronto.
What is not established about ingredients and safety?
The reviewed product pages do not supply a complete ingredient panel or independent safety testing. A starch-based description, or the manufacturer’s wording about additives, is not enough to establish that the litter is safe for every cat, hypoallergenic, or environmentally preferable. If you need ingredient details for a cat with a known sensitivity or health concern, consult the full packaging information and ask your veterinarian rather than relying on broad marketing language.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to assess whether it fits your needs
- Choose it for the intended role: decide whether you want to use it as OPET’s suggested booster or are considering it as the primary litter; the manufacturer specifically describes booster use.
- Consider fragrance: OPET calls it lightly scented, while one Chewy reviewer found the scent stronger than expected.
- Set expectations for performance: firm clumps, reduced sticking, odor duration, dust and tracking are seller claims, not independently measured comparisons.
- Check the package and listing: the product pages reviewed list 7.3 kg (16 lb); price and availability can change.
- Follow disposal rules: use local guidance rather than inferring flushability from the manufacturer’s description of a water-dissolving booster.
OPET’s USA litter collection shows other products in the brand’s range, but the reviewed sources do not provide controlled head-to-head results that would support ranking them against this litter. Cats.com’s product review is additional editorial context, not a substitute for product documentation or controlled testing.
