PETKIT Tofu Cat Litter with pH Indicator, Flushable Clumping Formula

PETKIT Tofu Cat Litter is a clumping, flushable tofu litter for everyday cat-box use, with 99.9% dust removal and urine pH indicator particles.

• Five-stage dust removal and 99.9% dust-free claim — helps limit airborne dust around the litter box.
• Larger granules — reduce litter sticking to paws and tracking across floors.
• Pea fiber and corn starch clumps — make waste easier to scoop.
• Flushable, water-soluble formula — offers a toilet-disposal option; flush only a small amount at a time.
• Urine pH indicator particles — provide a color-based visual clue to changes in your cat’s urine.
• Enzymes, legume-derived fibers and starch — help control odor and absorb urine.

This litter is made for cat households that want straightforward scooping, less tracked litter and an added visual aid for monitoring urine. Its composition and clumping action support routine litter-box care, while the indicator particles add a monitoring feature to the usual litter routine.

How do the pH indicator particles work?

The particles change color in response to cat urine, giving you a visual clue that may help you notice urinary changes earlier. They are designed to support observation, not to diagnose a health condition. PETKIT recommends using the litter with Purobot Max Pro 2 or the Purobot Ultra series for AI-camera-based urinary health monitoring.

• Urine color provides the visible indicator.
• Compatible with all PETKIT litter boxes.

Does PETKIT Tofu Cat Litter clump and flush?

Yes. Pea fiber and corn starch form dense clumps that set quickly and can be scooped out easily. The litter is biodegradable and water-soluble, dissolving within 30 seconds. It can be flushed, but flush only a small amount at a time.

• Made from corn starch and pea residue.
• 100% natural ingredients, as stated for this formula.

How does it help with dust, tracking and odor?

A five-stage dust-removal process gives the litter its 99.9% dust-free claim, and the larger granules are designed to adhere less to cats’ paws. For odor control, enzymes and fibers derived from legumes act at the source, while added starch absorbs and locks in urine within seconds.

• Designed to reduce paw-related tracking.
• Urine absorption and odor control are built into the litter formula.

PETKIT Tofu Cat Litter suits cat owners looking for clumping litter with a flushable disposal option, reduced tracking and a urine-color monitoring feature. It is made for use in PETKIT litter boxes, with the Purobot Max Pro 2 and Purobot Ultra offering the suggested AI-camera monitoring pairing.
