Hi there...The reason is psychological as well as physiological--the two are not mutually exclusive of one another. Cat's purr whenever they feel content, extremely frightened and some will purr when they are dying as well.
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 pump, pushing air in and out of the vibrating cords, thus creating a musical hum. Some veterinarians 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.
The other theory is that the sound comes more from vibrating blood vessels than in the voicebox itself. The larger the vocal chords the softer the purr whereas the smaller the louder.
Scientific Reason cats purr:
Some scientists believe when cats purr the frequency of their purring will help heal damaged bones and body organs as well as help heal humans.
All the cats had purr frequencies between 20 Hz and 200 Hz. With the exception of the cheetah, which had frequencies 2 Hz from the rest, all the species had frequencies, notably 25 Hz, 50 Hz, 100 Hz, 125 Hz, and 150 Hz, that correspond exactly with the best frequencies determined by the most recent research for bone growth, fracture healing, pain relief, relief of breathlessness, and inflammation. All of the cats' purrs, including the cheetah, had frequencies 4 Hz from the entire repertoire of low frequencies known to be therapeutic for all of the ailments.
That fact that the cats in this study produced frequencies that have been proven to improve healing time, strength and mobility could explain the purr's natural selection. After a day or night of hunting, purring could be likened to an internal vibrational therapeutic system, a sort of "kitty massage" that would keep muscles and ligaments in prime condition and less prone to injury. Additionally, the purr could strengthen bone, and prevent osteodiseases. Following injury, the purr vibrations would help heal the wound or bone associated with the injury, reduce swelling, and provide a measure of pain relief during the healing process.

They can also purr when they are in pain as well. This usually occures near the end. People have said their cat purred shortly before the euthanasia process. I read this on the ASPA site under behavorial situations....In actuality no one really knows why they purr, we like to think they are content...That's good enough for me.

Purring isn'tjust an auditory phenomenom, it can also be felt as vibration. When kittens are newly born, they are blind, they have no sense of smell, and their ears are undeveloped. Therefore, their main reaction is to the purring vibrations of their mother, which acts as a homing device.

It's their original language if you can call it that.... But we humans didn't hear it so well, so they got adjusted and started mjauing as well! To get our attention! That's the history of cat language in a short version! They even start perring when they are hurt... so it has nothing to do with a good feeling!

"Information" hon.
Not even scientists know why cats purr. They purr when they are happy and they purr when they are in pain/distress.

Their purring sure gets them what they want from the people around them. Maybe they do it for us.

Why do you moan if/when you reach climax???
It's a somewhat involuntary response to a GOOD feeling.
