ScoopFree Litter Trays ensure you don't have to see, touch or smell messy waste. These disposable replacement trays are for use with the ScoopFree Self-Cleaning Litter Boxes only. Each litter tray is pre-filled with Premium Blue Crystals that begin to immediately absorb the urine (and its odors) and dry out solid wastes right after your cat exits.
Replace litter trays according to the following schedule: at least once every 20-30 days for one cat, every 10-15 days for 2 cats, and every 7-10 days for 3 cats.
Litter tray measures 14.5" x 22" x 2.5" high.
