Wounded cats will purr because it helps to heal and strenghten bones and organs. Cats purr at between 27 and 44 hertz, exposure to similar sound frequencies is known to improve bone density in humans. Purring is believed to have a similar effect to ultra-sound treatment on humans.
The experts say that there is no obvious reason for a cat to purr just to show contentment - what these experts do not realise is that we purr to get round humans, cajole nice tuna meals and treats, etc, out of them! Dr David Purdie, from Hull University, has a theory that the human skeleton needs stimulation to prevent it losing calcium, he says that purring could be the cat's way of providing that stimulation for it's own bones.

The Physiology of Purring
There seems to be two schools of thought here.
The most popular one is quoted here:
One study determined that purring involves activation of nerves within the voice box. These nerve signals cause vibration of the vocal cords while the diaphragm serves as a piston pump, pushing air in and out of the vibrating cords, thus creating a musical hum. Veterinarian Neils C. Pederson, author of Feline Husbandry, believes that purring is initiated from within the central nervous system and is a voluntary act. In other words, cats purr only when they want to.²
The other theory is that the sound comes more from vibrating blood vessels than in the voicebox itself. ³

Purring is perfectly normal. Some cats really get a vibration going. It sounds funny but it really is quite normal. Be happy that your kitty is so content that he does express himself...

The vocals in their throat vibrates. the way the blood flows through it makes it vibrate, and you get the purring noise.
