Abstract: A corner bracket structure for fastening together a pair of panels includes a first elongated member having convex projections extending from one side thereof. A second elongated member has a concave elongated channel extending from one side thereof. The elongated channel includes retaining regions for capturing the projections. The retaining regions are spaced apart from each other by recessed regions that initially receive the projections. The projections are inserted into recessed regions, and slid into the retaining regions to form a semi-hinged connection.

Abstract: A stackable, nestable pet shelter includes first, second and third housings. Each housing has a top of a predetermined shape and sidewalls that extend downwardly, and taper somewhat outwardly, toward an open bottom. In use, the bottom of the second housing rests upon the upper portion of the first housing, and the bottom of the third housing rests upon the upper portion of the second housing. The first and second housings are substantially hollow. When not in use, the third housing nests within the second housing which, in turn, nests within the first housing. An opening is provided in the sidewalls of the first housing for allowing an animal to enter or exit. The top of each housing includes an opening for allowing an animal to pass from one housing to the next.
