A domestic cat purrs between 25 and 150 hertz
The vibration comes from muscles in the larynx rather than the vocal cords alone Purring happens on inhale and exhale, which is why it sounds continuous. Kittens purr from a few days old, and adult cats purr when content but also when injured. Low frequency vibration has been studied for possible effects on healing. It sits in Mondo's animals collection, one of 200 facts that each trace back to the reference below.
