Abstract: A modular animal transportation crate includes a plurality of panels that form the floor, walls, doors and ceiling of the crate. The panels are connected to each other by panel and section connectors. The panels may include perforations which protrude away from the animal. The perforations provide ventilation through side and top when used as walls or ceilings and assist in the removal of waste products when serving as the floor. The inventive crate is preferably made of a strong lightweight material that is easily assembled, disassembled and re-assembled. The crate may also be used to transport animals and to house the animals at remote locations.

Abstract: A cage that includes two or more movable "walls" that can restrain an animal in two or more dimensions is disclosed. Preferably, the invention includes "telescoping" or movable planar surfaces, one preventing an animal's lateral movement, and another preventing vertical movement. An animal restrained in the inventive cage reduces the possibility of injury to the handler and the animal. In addition, it can be used to accommodate animals of differing sizes, because the walls of the disclosed restraining cage are movable.
