Abstract
Abstract A sales package for litter in the form of a double disposable litter container comprised of two sections which telescope, in closing, to encompass a pair of separate packages of litter and which, when separated, comprise two separate disposable carboard litter boxes, each of which is used with one of the two packages of litter and has improved functional characteristics as to durability and absorption of liquids and odor. Each of the sections fucntions as a separate disposable litter box and is characterized by a plurality of highly absorbent paper panels superimposed upon its bottom panel and a highly porous hard-surfaced scratch-resistant panel having a surface hardness factor of a critical wax strength number range of approximately 8-11 superimposed with respect to the absorbent paper panels, to support the litter and protect the highly absorbent panels against scratching by the animal.
