Abstract
This disclosure relates to a tray containing litter for use by an animal. The tray is formed of plastics and comprises a planar floor having at least one deformation acting as a fold line and a plurality of upstanding sidewalls. Each of the sidewalls is free of any fold line and is connected to the floor to form an open compartment. Each of the sidewalls also comprises an upper edge. At least one complementary engagement means is disposed on each of the sidewalls. The complementary engagement means is integral with the sidewall. The tray is adapted in use to retain its shape and is foldable to a closed condition for disposal. The deformation is arranged to permit the tray to be folded to bring the upper edge of the adjacent sidewalls together to enable engagement of the complementary engagement means to seal the tray and the contained litter.
