Abstract: A cat feeding enclosure comprises a plurality of exterior walls enclosing an interior space, an entry opening for a cat to enter the interior space, a feeding area in the interior space for accommodating a receptacle for holding cat food, and an interior wall within the enclosure defining a circuitous path for a cat to walk along from the entry opening to access the feeding area. The entry opening is preferably no larger than necessary to accommodate passage of a large size cat therethrough. The circuitous path has a plurality of sharp turns to prevent a dog from following the circuitous path from the entry opening to the feeding area.

Abstract: A birdhouse entrance is provided with an entrance opening having two posts projecting vertically from the bottom edge of the opening toward the top edge. The two posts are spaced apart such that a bird of selected size cannot pass between them without opening its wings. Sufficient clearance for the wings is provided between the outer edges of the posts and the side edges of the entrance opening.

Abstract: A feed enclosure for birds and small creatures such as squirrels, raccoons or the like. A internal floor to ceiling enclosure partition prevents feeders from one side of the enclosure from entering into the feeding area entered from the other side. Small birds may enter from one side of the enclosure while larger birds and small creatures can feed from the other side. The larger birds may feed through an elevated opening by stretching their necks over a lower apron while the small creatures can enter into one of the two enclosed areas by one or more lower openings. Smaller birds enter the enclosure's other side through smaller spaced vertical partitions located over a lower wire mesh fence through which the small creatures are prevented from entering.

Abstract: A pet bath apparatus includes a sloped floor unit which includes an elevated portion, a lower portion, and a drain portion located in the lower portion. A set of support legs project downward from the sloped floor unit. A pair of end wall units and a pair of side wall units are supported by the sloped floor unit. Connector assemblies are supported by the wall units and selectively connect adjacent wall units together. The sloped floor unit includes an elevated mid-portion and two lower portions sloping downward from the elevated mid-portion. The drain portion includes a plurality of drain apertures. The sloped floor unit includes a pair of support ridges projecting upward from side portions of the sloped floor unit, and each side wall unit includes a flange portion projecting outward from an inside side wall surface and in engagement with a support ridge. Each side wall unit includes a pair of alignment-pin-receiving elements which project outward from end portions of the inside side wall surfaces.
