The Crystal Deluxe litter box from PetSafe is an all-in-one litter box, designed to work specifically with Crystal litter. As your cat uses the box, PetSafe Premium Crystal litter absorbs urine and dries out solid feces for odor control 5 times more effective than clumping clay litter. The tray features a removable tray containing an absorbent mat that retains urine that Crystal litter doesn’t immediately absorb, enhancing the odor control action. Openings along the bottom of the tray allow air to circulate to dry out the Crystal litter, prolonging its life and freshness. A grid on the front of the box prevents litter from splashing outside the box and onto the floor. A bag of Crystal litter lasts up to a month in a single-cat household. The system includes a scoop to remove solid excrement.Contains: 1 cat litter box Crystal Deluxe; 1 refill of Crystal Premium litter; 1 litter scoop; 1 absorbent mat.
