The Polly's Pet Products Orthopedic Sandwalk Bird Perch can help to keep your feathered friend healthy and flap happy! This perch features random twists, turns and curves, so your birdie pal has to change his grip every time he moves. That movement helps to gently file your bird’s nails to keep them healthy. The twisted design makes your bird’s feet and legs work harder, strengthening muscles and keeping your pal active. The non-slip material helps to maintain a comfy temperature. The perch is also extremely lightweight, so you can easily set it up on the side of the cage.
