As the kitten grows into adulthood, purring continues. Many suggest a cat purrs from contentment and pleasure. But a cat also purrs when it is injured and in pain. Dr. Elizabeth Von Muggenthaler has suggested that the purr, with its low frequency vibrations, is a “natural healing mechanism.” Purring may be linked to the strengthening and repairing of bones, relief of pain, and wound healing (See Web link to Felid purr: a healing mechanism).The first theory is that the cat has an extra set of false vocal cords in their voice box, or larynx. These false vocal cords allow the cat to produce a soft rumbling noise for hours without even opening its mouth. This theory suggests that purring is very similar to heavy breathing, similar to snoring in humans. With every breath in and out the cat makes, the air passes over the false vocal cords and this makes the RRRRRRRRR noise of the purrrr and as the muscles of the larynx contact they cause the noise to be interrupted and vibrate.Have you noticed that when your cats discover a bird or a small rodent like animal through the windows, they start clicking their mouth, making a strange stuttering sound as their jaws vibrate in a frantic manner?
