Abstract: This invention relates to a disposable cat litter chamber. Being unique in nature this design provides increased sanitation features, minimized odors, and disposability. The box may be formed in various shapes, but the preferred embodiment is that of a "milk carton" type construction, only somewhat taller and elongated. The cat enters the chamber through a flexible expansion type door at either or both ends. This chamber remains entirely sealed at all times except for slits in the door. Windows for light emission would be glazed with cellophane or equivalent. All excretions and resulting odors are confined within the chamber. This invention also totally eliminates the unsightliness of conventional cat boxes and also prevents any litter from being expelled out of the box during use. The chamber can be made of cardboard or other suitable material so that the entire unit may be disposed of after use. This feature prevents any necessity for direct or even visual human contact with the litter.
