Catgut is a strong thread made from the of animals — the long food-tubes inside the body — and used for the strings of violins and similar instruments. Doctors also used it, in older surgery, to the body, because the thread could slowly disappear as the body healed. Though actually it is almost never from a cat, despite the name; it is usually from sheep or goats. Players may still say catgut even when the string in their hand is metal or factory-made. The name is a puzzle, not a recipe.
腸線、羊腸線（樂器弦；不是貓腸）
組成Uncertain. Possibly a shortening of cattlegut (cattle + gut). Another idea is that it comes from kitgut or kitstring — kit once meant a small fiddle — and people later heard kit as the word for a young cat.
