It turns out that cats have special wiring! The wiring travels from the brain to the muscles in the voice box, and this wiring is able to vibrate the muscles so that they act as a valve for air flowing past the voice box. The muscles work both during inhalation and exhalation, which creates the impression that cats can purr continuously. The air passes through the valve, which opens and closes rapidly to create the purring sound.
when a cat purrs its the sound that they make to show contentment and happiness. this sound is made by the cat vibrating the air in their throats and when it comes out it makes the purring sound.

They are able to vibrate the muscles in their larynx (voice box) so that they act as a valve while inhaling and exhaling making a purring sound.
It's really neat.
They have a muscle in their throat and when they become relaxed it vibrates.
