Gizmo is a stylish litter tray with removable rim. The holes in the rim prevent litter from falling outside the tray when leaving. Moreover, the raised back keeps urine and litter inside for a clean & tidy area around the tray. Finally, the Gizmo tray has a low entrance which makes the tray suitable for younger, elderly, and sick cats. For a fast & easy cleaning and extended lifetime of the litter tray, we recommend using litter trays bag Bag it Up Medium for Gizmo Medium.
