Question

How do cats purr?

Answer 1

Cats produce a purring sound by using their laryngeal muscles to open and close their glottis rapidly (about 25-150 vibrations per second). This creates the familiar soothing sound that we associate with content and happy cats.

Answer 2

Cats purr by using their laryngeal muscles to rapidly twitch and vibrate, creating a continuous sound that we perceive as purring. This can occur when a cat is content, relaxed, or even when they are in pain or distress.
