Abstract
A disposable litter pan that is made of a flexible material, preferably biodegradable non-plastic material, such as thermally pressed cardboard or other paper fiber material treated with an aqueous coating that inhibits degradation of the pan in the presence of fluids. The pan is a generally self-supporting pan structure having two end walls, two sidewalls, and a floor; wherein the floor having several perforations, openings, or orifices sized to allow unused cat litter to be sifted into a retaining pan underneath that can be of the same or imperforate construction. The litter pan folds, allowing the sidewalls to engage in a manner that does not allow litter or excrement to escape. The pan can be retained in the folded condition by an integral latching arrangement that also can serve as a handle.
