Odor, dust & tracking
Odor: Scent can mask smell for humans but may put cats off. Scoop daily regardless.
Dust: Maker claims very low dust; still pour gently.
Tracking: Expect clay tracking; use a mat especially with auto boxes.
Switching tips
If moving from unscented to scented (or reverse), go slower than usual and watch for box avoidance.
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.
FAQ
Should I start a new cat on scented litter?
Usually no. Start unscented clumping clay unless your vet or your cat’s history says otherwise.
Robotic boxes?
Confirm your robot’s manual. Many want specific clumping clay; Platinum is often listed for that use case.
