cuttlebone
Bird cage supplement
Cuttlebone is the internal shell of a cuttlefish—a hard, chalky, oval structure that helps the animal control buoyancy.
Dried cuttlebones are commonly placed in birdcages as a source of calcium and a surface for birds to sharpen their beaks: The parakeet spent hours gnawing on its cuttlebone.
