A cat organ (German: Katzenorgel, French: Orgue à chats), also called cat piano (German: Katzenklavier, French: piano à chats), is a hypothetical musical instrument which consists of a line of cats fixed in place with their tails stretched out underneath a keyboard so that they cry out when a key is pressed. The cats would be arranged according to the natural tone of their voices.
