is/was there an evolutionary advantage to purring? if so why don't other animals do it?
I was once a STAR!!! Well part of a star at least.

This is like asking why babies cry. The proximal cause may be that they are hungry or uncomfortable, but the reason why is that they are helpless and have evolved a mechanism to tell their caregiver that something is needed.

So, what does this have to do with cat purrs? A good guess would be that because cats have a lot of dangerous equipment, and ones that purr really arenít very social in their natural habitat (often solitary), a specific auditory mechanism has evolved that would signal contentment. Because a purr is quiet, this social signal is obviously meant just for other cats that are very close. When a kitten purrs, this might quietly tell mom that everything is OK or mom might purr to let her young know that it is safe.
