A box for cat elimination use that simplifies clean-up, features only eco-friendly components, and is not expensive. The design includes 3 parts: box, trays and pad. The 12×18 wax coated cardboard box is sturdy and long lasting, and with proper use may not need replacing indefinitely. The waxed lift-out tray is a single design with handles on each short end, and is used on 2 levels inside the box: the lower lift-out tray (#1) is used to hold a reusable, washable, absorbent, compostable wool pad the upper tray (#2) provides the animals usage surface. The trays feature paw print-shaped die cuts, which allow excess fluid to flow from the top tray to the pad below. The trays are interchangeable the bottom tray is used solely for the purpose of transporting the soiled pad from the box to the washing machine. The box should be used with paper-based litters, and may used with no litter if desired, once the animal learns to use the system.
