Why do cats purr?

ANSWER

Purring is the most common sound cats make. Yet, we know less about it than meowing, chirping, chattering, hissing, and growling.

Yes, cats purr when they're content. But you shouldn't assume that sound means your cat is in a good mood, or that it's the only time you'll hear it. Cats purr to communicate other emotions and needs, too.
