From a medical point of view, the skeleton of cat throat is composed of thyroid cartilage and cricoid cartilage. The laryngeal cavity is divided into 3 parts, the upper part is the laryngeal vestibule, and the trailing edge is the false vocal cords. The cavity between the false and true vocal cords is the second part of the laryngeal cavity. The third part is the cavity between the vocal cords and the cartilage ring, which is very narrow. A cat's purr is made when the falsetto cord vibrates and resonates through the throat cavity.
