Abstract: A method of housing a gerbil or like pet. Sections of cardboard are formed into a first housing structure for the pet, and the structure is placed in a container whose walls are transparent or have openings through which the container's interior can be viewed. The container is closed after placing the pet in the housing structure, and pieces of the cardboard sections start to accumulate at the bottom of the container as the pet chews on the sections. Some of the chewed pieces form bedding for the pet while other pieces absorb pet waste. Once the housing structure is substantially chewed into pieces, the container is opened and the chewed pieces are removed. A second housing structure formed of cardboard sections is placed in the container, and the container is closed after the pet is placed in the second housing structure.
