Why do cats purr loudly2007-11-25 12:31:46

Why do cats purr loud? I know it's because they're happy but what causes it?

Answers:

Hi Dave.one study determined that purring involves activation of nerves within the voice box. These nerve signals cause vibration of the vocal cords while the diaphragm serves as a pump, pushing air in and out of the vibrating cords, thus creating a musical hum. Some veterinarians believes that purring is initiated from within the central nervous system and is a voluntary act. In other words, cats purr only when they want to.

The other theory is that the sound comes more from vibrating blood vessels than in the voicebox itself. The larger the vocal chords the softer the purr whereas the smaller the louder.

Also cats purr to show they are content, happy and some will even purr when they are in extreme pain or when dying.

CUZ THEY FEEL LIKE IT. DUH!

---

most scientists agree that the larynx (voice box), laryngeal muscles, and a neural oscillator are involved.

---

they have special mechanisms in their thorat that vibrate, hence the purring sound.

Purring is just a vibration of the vocal cords in cats. Some are just louder than others, just like some people can speak or yell louder than others. Purring doesn't always mean they're happy. They also purr when they are nervous or scared.

this article says that the volume of a cat's purr can vary among cats - so maybe yours purrs louder than others.
