Why Cats Purr

A lot has been written about why cats purr. Many people think that cats purr when they’re happy. And they do purr when they’re happy. They may also purr when they’re hurting from sickness or injury. So what is a purr and why do they do it?

The Om Vibration

When cats purrs they set up a vibration that emanates from their vocal chords and spreads outward. It builds both in the outward breath and the inward and can envelope the entire body, distributing a soothing, healing sensation throughout. Watch a cat deeply into purring for an hour or so and you will see his entire body is enveloped in a constant and comprehensive vibration. It is very much like the Om chant used in yoga and meditation practices.
