Abstract: A modular bird or animal cage accessory assemblage generally made of resilient materials, includes interchangeable rods engageable with a C-shaped system clasp having a corresponding channel guide for receiving the rods therein. The rods are held in place by a combination of the position of the rods within corresponding channel guides of one or more clasps and by the use of central sphere branched connectors, which branched connectors may be rapidly and easily loosened for dismantling of the assemblage, so that the rods can be re-used in other configurations. A systematic plurality of rods is provided with incremental dimensioned variations, so that the size of the assemblage can be varied while preserving the ability to create hollow spaces between the rods. Expansion of the size of the containers is accomplished by axial connection of the rods.

Abstract: An animal play apparatus, adapted for use with or without an animal play enclosure with towers, having one or more rotatable housings. Each of the housings has a doorway and is rotatably mounted on a bracket having two arms connected by a base which has a port therein in congruent relation to the gate when the housing is in a predetermined operative position. Each bracket is adapted for connection with said towers, whereby there is communication between the interior of the enclosure and that of the housing when the latter is in its operative position. The arms of each bracket have a releasable lock operatively engageable with the corresponding rotatable housing.
