  • Publication number: 20050081795
    Abstract: The therapeutic bird perch is a plastic or wood perch having two surface textures, a grooved surface and an abrasive surface. The grooved surface is formed by etching a series of parallel grooves into the surface of the perch. The abrasive surface coats the grooved surface on a portion of the perch only, and is made of resin and sand. The abrasive surface comprises at least two layers: an inner layer of resin and an outer layer of sand laminated to the perch by the resin. The perch can be used alone as a single perch, or in multiples to form rungs of a therapeutic bird ladder. The ladder rungs have different diameters to exercise the feet.
