Cuttlebone is an excellent source of calcium and minerals for your small bird or parrot. It's derived from the natural cuttlefish and the rough texture of the bone is perfect for helping your bird trim its beak. Because it has texture it provides a satisfying pecking, chewing, and scratching experience. The Cuttlebone comes in small and large sizes both in single and twin packs. You'll want to keep them on hand for your bird.
