Purrfect use of Occam's razor. They cut away the parts of the cat not needed for purring. Experiments were performed on eight excised larynges. The researchers built a cybernetic purring machine. "[subglottal pressure] was controlled automatically by gradually opening and closing a magnetic valve in the air supply chain. This valve was voltage-driven through a signal emitted by the LabJack U6 DAQ, controlled by a custom Python software and graphical user interface (GUI) written by CTH." Like catgut, cat larynges might be use in future musical instruments.
