Verdict: Solid plant-based clumping option made from whole-kernel corn. Lighter than clay to pour; listing warns not to mix with non-clumping litter. Still bag solids and trash them — do not flush.

Odor, dust & tracking

Odor: Depends on scooping discipline. Unscented plant litters rely on removal of waste, not perfume.

Dust: Listed as low dust; still avoid aggressive pouring near HVAC intakes.

Tracking: Granule size varies by lot — mats help.

Switching tips

Transition gradually. Keep depth modest (~1–2 in) unless the brand says otherwise.

General hygiene: scoop daily; Toxoplasma in feces is not immediately infectious (CDC notes 1–5 days) — daily changes reduce risk. Pregnant people and immunocompromised folks should follow clinician guidance for litter duty.
