and why do they do it?

When my cats purr, I'm not sure who is happier,them,or me.The purr comes from two membrane folds called "false" vocal cords, that are situated in the larynx behind the actual vocal cords. Cats purr at 26 cycles per second,the same as an idling diesel engine! The cat will purr when she breaths in, and when she breathes out. Scientists think purring is produced by blood in a large vein in the chest cavity that vibrates and is then magnified by air in the windpipe.Oh yes, and.......they're happy when they purr.

There is a number of theories what causes the purring sound. The one I'd go with, is air passing over the larynx and causing it to vibrate. Cat's don't always purr when they are happy, they have been known to purr after they have been ran over or are getting put to sleep. I suppose it just means they are "ok" with the the given situation.

Nobody knows exactly how cats purr. 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.
Cats purr when they are content and happy. They also purr when they are in pain or scared, as kind of a self soothing noise.

They purr when they are happy. At least that's what I understand.

Cat's purr when they are happy, or if you are one of those that believe that animals don't have emotions, it's when they are content.
Love as always,

well to be exact the purring sound is the vibration of the cats vocal cords and it expresses extreme emotions...

Animal behaviorists have come to the conclusion that it's like "humming" cats do that when they are content and reciprocating love.

It's a good sign. It means that they're in a state of comfort, that's all.
