Abstract: An animal containment system includes a cage with a lid and a water flask. The water flask has a generally rectangular footprint and sits on top of the cage, preferably on the lid itself. A sipper tube connected to a port on one of the sides of the water flask can be inserted through a hole in the cage lid to a height sufficient for the animals in the cage to reach up to obtain water. The lid of the cage preferably includes a recessed portion in which at least a portion of the water flask is disposed. The water flask includes a bottom surface that is sloped to facilitate emptying of the flask into the sipper tube. The water flask has a relatively low profile and thus, contributes very little to the height of the cage. Thus, existing rack designs can be used to house the same number of cage and water flask assemblies of the present invention as was possible with conventional isolation cage and water bottle designs. Further, the water flask can be replaced without having to remove the lid of the cage.

Abstract: An improved mold releasing technique including use of moveable segments to form a part of the male portion of the mold, and the unique product formed thereby is described. The moveable segments which disengage from integral contact with the product once it is formed, permit the formation of the uniquely formed product which includes side and end walls which can be less than 1 degree off vertical. This enables the manipulation of the product design parameters including each wall angle at various points along the wall to achieve a desired wall surface profile especially in the vicinity of the product floor. This results in an increased surface area at or near the product floor which permits a greater number of animals to be housed in the cage product in accordance with Federal guidelines. The tailoring of the wall profiles also allow for the nesting of the products and the accommodation of prior art covers and accessories.

Abstract: A group of connecting homes (20), commercial and/or not-for-profit buildings that serve to enclose a self-sustaining wildlife habitat sanctuary (23), specifically targeting the natural environment of endangered species, where appropriate. The homes (20) serve as an impenetrable cage wall (8), much like the walls of a mountain valley, preventing animals from entering or exiting the habitat, with the possible exception of migrating birds and fish. On one side of the homes there is a self-sustaining habitat (23) and on the other side of the homes there is modem civilization. The walls of the homes facing the habitat may have shatterproof glass windows (5) or a caged terrace (6), allowing inhabitants of the building to safely observe the enclosed habitat, and human access to the habitat may be restricted to observation through windows, observation from the caged terrace, or hikes through caged walking paths (14, 15, 16, 17).
