Abstract
A lightweight cage is composed of an arrangement of one or more panels that define an enclosed space in which an organism is contained. Each panel includes an inner surface that at least partially define the enclosed space. The panels are made of a surface and urethane insensitive material such that the waste produced by the organism held within the enclosed space will not adhere to the inner surface. In one aspect, each panel may include an inner member defining the inner surface and an outer member fixedly supported spaced from the inner member such that a highly advantageous insulation property is imparted to the panels. In another aspect, a method of fabricating a lightweight cage is described. The panel arrangement is fixedly assembled by chemical fusion to define the enclosed space in which the organism is to be kept.
