Cuttlebones provide calcium for birds. It serves as a natural and valuable source of calcium, which can be essential for maintaining strong bones, beaks, and eggshells. Calcium is particularly important for birds during breeding, molting, and periods of growth. Additionally, birds also enjoy nibbling on cuttlebones, which provides them with mental stimulation and helps keep their beaks trimmed.

Cuttlebone can be important for tortoises due to its rich calcium content. Calcium is a vital mineral for tortoises as it can support the development and maintenance of a healthy shell, bones, and overall skeletal structure. Tortoises require a balanced calcium-to-phosphorus ratio in their diet, and cuttlebone is a natural and effective source of calcium. Providing cuttlebone to tortoises can help ensure they receive adequate calcium. Cuttlebone can be important for bearded dragons because it provides a rich source of calcium. Bearded dragons require a proper calcium-to-phosphorus ratio in their diet to support proper bone development, muscle function, and other physiological processes. Calcium is particularly essential during their growth phase and reproductive cycles. Cuttlebones offer a natural and easily digestible form of calcium, allowing bearded dragons to regulate their calcium levels effectively. Regular access to cuttlebone can help to prevent calcium deficiency. Additionally, the texture of cuttlebone provides a beneficial chewing and jaw exercise for bearded dragons. Cuttlebone can be important for snails due to its high calcium content, which is essential for their shell growth and maintenance. Snails rely on calcium to form and strengthen their shells, providing protection and structural support for their bodies. Calcium deficiency in snails can lead to weakened or deformed shells, making them more vulnerable to injury and predation. By providing cuttlebone to snails, it ensures a readily available source of calcium that they can consume and utilize for shell development. Additionally, the rough texture of cuttlebone helps snails wear down their constantly growing teeth.
