Disposable pet toiletry system

A disposable toiletry system for pets comprising:

• a flexible collapsible tubular container closed at its ends and formed of biodegradable material for shipping and storing cat litter and for independent use as a semi-rigid self-supportive cat lifter pan;
• absorbent cat litter enclosed in said container;
• said container including opposed side walls and end walls, a bottom wall and a top wall, opposed ones of said sidewalls being foldable from upright positions to positions folded over the cat litter to allow said top wall to collapse about the cat litter toward said bottom wall so that the cat litter bears the weight of objects resting on the container during shipment and storage of the container and its contents;
• said top wall defining separation means for opening said top wall to form an open top container with at least one flap that is foldable to a position extending about a side and beneath the container;
• said side walls and end Walls being unfoldable to upright positions to erect the container and to contain the cat litter and to form a semi-rigid sell-supporting cat litter pan;
• and
• a locking fill valve for partially filling the container with absorbent cat litter and then locking the valve to prevent the spillage of cat litter from the container;
• so that when the top wall of the container is opened and the at least one flap is folded about the container and the side walls and end walls are unfolded to rigidify the container, the container functions as a semi-rigid cat litter pan.
