Sustainably Yours - Large-Grain Formula For Minimal Tracking

TL;DR: Sustainably Yours Large-Grain Formula is a plant-based cat litter made from cassava and corn, with oversized granules designed to minimize tracking outside the box. It suits multi-cat homes, long-haired cats, and owners who want a flushable, biodegradable litter instead of clay or silica.

The large granules are sized so they're less likely to lodge between toe beans or ride out of the box on fur. For most households, that means less sweeping and fewer stray granules two rooms away.

Because the base is plant material, the litter clumps firmly on contact with moisture and helps trap odour without synthetic fragrances or chemical deodorizers.

What makes this large-grain cassava litter different?

• Large-grain texture — granules sized to reduce tracking outside the box
• Cassava and corn base — plant-based, with no added synthetic fragrance
• Firm clumping and odour control for faster daily scooping
• Flushable and biodegradable, where local plumbing allows
• Available in 13 lb and 26 lb bags — choose 13 lb for a single cat, 26 lb for multi-cat homes

Specifications

Who is it for?

Sustainably Yours large grain cat litter is built for households with long-haired cats, multiple cats, or a litter box in a carpeted or high-traffic room. If you've used small- or medium-grain plant litters and still find granules on the floor, the larger grain size is the logical next step.

It also fits owners who prefer a plant-based, flushable litter over clay or silica options. Kittens still learning the box, or cats with a strong preference for fine sand-like textures, may do better on a finer grain.

How do you use large-grain litter?

Fill a clean litter box with roughly 2–3 inches of litter. Scoop clumps and solids daily and top up as needed to maintain that depth — consistent depth is what keeps clumps intact when you lift them.

Small, soiled clumps can be flushed a few at a time where local plumbing permits; otherwise, dispose of them in the trash. Empty and wash the box fully every few weeks, depending on how many cats are using it.

Switching from another litter? Mix the new litter with the current one over 5–7 days, increasing the cassava blend gradually so your cat accepts the change rather than avoiding the box.

Pair the Sustainably Yours large grain minimal cat litter with a roomy setup like the Petmate - Large Basic Litter Box, which gives the larger granules space to settle and keeps more of them inside the box.
