The Regular Sand Perch from Insight by JW is designed specifically to help keep mess inside the cage. This perch is wider at the base and then gradually gets more slender as it extends into the cage. This keeps the bird perched on the middle to end rather than right near the side of the cage. The natural sand is part of the mold, not sprayed on and so is durable and comfortable for your bird. Suitable for parakeets and cockatiels and other similar sized birds.
