Abstract: An improved mirrored bird toy is provided that includes an interior multiple reflecting capacity that can reflect multiple reflections of a pet bird in multiple directions. Exterior exposed edges of the various mirrors may be plastic coated for safety. The lower or bottom mirror may include a cut-out whereby the bird can gain better access to the toy. The toy is mountable, within a cage, to the cage bars using a screw and nut. An orienting gage is disposed on the reverse side below the screw nub.

Abstract: A birdcage feeding device is provided with a seed chamber, seed cup, and method of attachment. The feeding device comprises an opening that may be opened or closed in order to displace seeds from a feeding chamber to fill a seed cup. The seed cup is designed to be shallow such that seeds do not get buried under layers of empty shells and hulls. The seed cup also has high rear and side walls to guard seeds from being scattered outside by birds. The feeding device may be closed to allow a user to remove the seed cup, without removing the device, for cleaning. A method of attachment is also described that allows the device to be on the outside of the birdcage while being secured from the inside of the cage, thus allowing for easy refilling of the device.

Abstract: A fastener for the suspension of a birdcage toy or the like has a first end terminating in a first loop, and a second end terminating in a second loop, each of the first and second loops terminating in a free end that allows for easy attachment of objects to the loops. An additional section is defined between the loop free ends to assist in preventing the free ends from deflecting outward, resulting in possible inadvertent detachment from the cage or retained object.
