Cuttlebone pieces of varying width, depth and length.  

There are two readily available forms of calcium. Calcium Carbonate which is most effective and is used in many of the vitamin supplements, and Calcium Phosphate which is found in cuttlebone. 

Please note that boxes of cuttlefish contain many broken halves, your bag may include larger pieces. These can be used in the same way as whole pieces by placing them in a cuttlebone holder/clip or left on the cage floor as a forage item.

For those who prefer broken pieces or like to grate cuttlefish, we are now offering a 250g of cuttlebone 'bits and pieces' which are the smaller broken pieces.
