Have no dog in this fight but quick google search...
Dr. Jamie Richardson, medical chief of staff of Small Door Veterinary in New York City, explains that a cat’s purring involves the brain, larynx (the throat), and diaphragm (the muscle responsible for breathing, separating the chest and abdominal cavity). “This complex process starts in the brain, which signals nerves to the larynx and diaphragm to oscillate, causing tension on the glottis, which contains the vocal cords,” she says. “When the cat then breathes in or out, a purr results due to the tension/relaxation on the glottis.”
A cat’s laryngeal muscles can flutter at a frequency of 25 to 150 Hz (vibrations per second), producing a low, continuous buzzing that is both audible and palpable. These low frequency vibrations are known to heal bones and relieve pain in muscles, tendons, ligaments and joints. If you find your cat purring away as she rests or after a fall from a fence, she’s helping herself heal.
