Abstract: A rectangular box container utilized for the deposition, temporary storage and disposal of pet cat excrement. The box container is pre-loaded with absorbent granular litter material and prior to use is shipped and stored in a compact rectangular state, approximately thirteen (13) inches wide, twenty one (21) inches long and three (3) inches tall. To use, the box unfolds to erect a larger rectangular box chamber, approximately thirteen (13) inches wide, twenty one (21) inches long and thirteen (13) inches tall. The rectangular box chamber, in its erected state, provides an opening through which a cat may enter the box to gain access to the pre-loaded absorbent granular litter material inside the box and, after use, exit the box. The container may be used in this erected state to its useful capacity, after which the container is folded down for compact disposal.
