Twist and bend the Comfy Perch into any creative shape you want. Each end attaches to a wire cage, and it will hold its shape without the danger of wires or stiffeners being exposed, so your pet bird will rest comfortably. Pet birds need perches of varying lengths, thicknesses, styles, and materials to keep their grip strength and their feet healthy. Great for parakeets, cockatiels, parrots, canaries and finches.
