Why do cats purr?

I've always wanted to know why cats purr. I've heard it's because they're in a good mood or very nervous. But why is that?

Cats do indeed purr when they're contented, however they also do purr if wounded or anxious, as purring stimulates a response that mends their bones.

It is because they are happy, for attention. They don't car if it's you, the cat molester down the street, or the man who kills people for money.
