What common item, often sold for birds, is consistently recommended as a calcium supplement for keeping woodlice cultures?

Answer

Cuttlebone

For keepers cultivating woodlice, ensuring a source of readily available calcium is mandatory due to the high demand this mineral places on the organism during molting cycles necessary for exoskeleton maintenance. Among the recommended supplements are crushed, sterilized eggshells and cuttlebone. Cuttlebone, a porous bone-like material typically marketed as a calcium supplement for pet birds, provides an excellent, easily accessible mineral source that woodlice can graze upon as needed to reinforce their hard outer shells, thereby supporting long-term colony health.
