Dear Tabby, Why Do Cats Purr?

Do you think cats purr when they are happy and content? Well, you would be right, but they also purr when they are in pain. But WHY do cats purr, where does that sound come from?
According to Pamela Johnson Bennett, author of Why Cats Purr? .
“The theory that experts now believe to be most credible is that it’s created by the laryngeal and diaphragmatic muscles in combination with a neural oscillator. A message from a neural oscillator in the brain gets sent to the laryngeal muscles, causing them to vibrate. Their movement controls how much air passes through.”
The sound can be very soothing both for the cat and for humans. In fact, it’s even more beneficial that you may have thought. I discovered this interesting video that talks about the positive benefits of a cats purr citing studies that the purring can actually helps injured cats heal themselves and improve their bone density.


Does your cat purr? How does the sound make you feel?

  4. It’s very relaxing and comforting. One of our cats, Katie, had a very loud purr though, and sometimes in the middle of the night it wasn’t appreciated as much!

  5. Purrs sooth me. If a cat is purring in the clinic during a ascult of the heart we have to put some rubbing alcohol in front of it’s nose to get them to stop purring long enough to make sure the heart sounds fine.
