Catgut [SEP] Introduction
Catgut (also known as gut) is a type of cord that is prepared from the natural fibre found in the walls of animal intestines. Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle, hogs, horses, mules, or donkeys. Despite the name, catgut manufacturers do not use cat intestines.
