Keep your cat’s litter area fresh, clean, and virtually hassle-free with the PETKIT Crystal Litter Set in Fresh Green. Specially designed for automatic litter boxes like the Purobot Crystal Duo, this complete 4-pack set includes disposable litter trays, premium crystal litter, and convenient waste liners for easy replacement. The highly absorbent silica crystals rapidly lock in odors and moisture while releasing a light, refreshing scent, helping neutralize unpleasant smells before they spread. With 99% dust-free, lightweight crystals that minimize tracking, cleanup is cleaner and gentler on both your home and your cat’s respiratory health. Simply swap out the tray when needed — no scooping, no mess, and no stress. Ideal for busy cat parents who want lasting freshness with minimal effort.
