ABSTRACT:
A pet cage door with a raised central section comprising a rectangular screen formed of a plurality of spaced horizontal and vertical wires coupled in a mesh-like configuration and constituting a door, the door being positionable over the front screen of an animal cage formed with a rectangular opening of a predetermined height and width, the door being formed of horizontal and vertical wires with a height and width greater than the height and width of the opening; the rectangular screen having a raised central portion and peripheral regions formed vertically and horizontally as extensions of the central portion, the peripheral portions being beveled at an angle with respect to the central portion and terminating in horizontal and vertical end wires adapted to contact the front screen of the cage when the door is in a closed orientation; a plurality of wire loops encompassing an endmost wire of the door and an adjacent wire of the cage front screen to constitute a hinge for opening and closing the door, at least one of the loops adapted to be located between an endmost wire of the door and cage front screen to preclude excess shifting of the door with respect to the opening; and a locking member formed from a semi-rigid wire having a loop at its central extent secured by wires to the central portion of the door along one edge remote from the hinge, the loop extending to a location beyond the door and opening and formed with a curve adapted to be releasably moved by a user to encompass a central wire of the cage front for locking the door with respect to the opening.
