cuttlebones
Budgie cage supplements
Cuttlebones are the internal shells of cuttlefish—lightweight, chalky structures composed mostly of calcium carbonate.
They're commonly placed in birdcages as a mineral supplement and beak-sharpening tool: The parakeet gnawed on its cuttlebone.
Jewelers and metalworkers also use them as molds for casting small objects, since the porous material holds fine detail.
