The Petkit Crystal litter for the Purobot Crystal Duo is a high quality system solution that combines high performance silica gel crystal litter with a disposable litter tray specifically designed for this automatic litter tray. The silica gel absorbs urine quickly, dries solid waste efficiently and minimises odours without additional fragrances, making it suitable for sensitive cats and odour-free households. The integrated leak-proof tray prevents urine leakage and allows up to 30 days of use for a single cat, while each tray typically lasts 20 to 30 days, depending on the cat's age, diet and health. The kit contains bagged silica gel litter and disposable trays with disposal bags and has a shelf life of 24 months. Once the tray is filled and inserted, no scooping or refilling is required until the next replacement, providing a convenient and hygienic cleaning experience. With its odour control, reduced maintenance and precise compatibility with the Purobot Crystal Duo, this crystal scatter system offers long-term efficiency and a cleaner, more pleasant living environment.
