cinco-purrsThere are not many things cat owners love more than the sound of their sweet kitty’s purr. We tend to associate it with the comfort and happiness of our cats. The whole thing seems so simple, but as it turns out, there is a lot to know about purring. Here are 10 facts you may not have known about purring.
 

Facts about Purring

  1. Cats are not the only animals that can purr. Other purring animals include mongooses, civets, hyenas, ginea pigs, genets, and raccoons.
  2. Cats purr at a frequency between 25 and 150 Hz (vibrations per second).
  3. Scientists still don’t entirely know how a cat purrs. It appears to be that signals from the brain cause the laryngeal muscles vibrate.
  4. Cats that can purr can’t roar and vice versa.
  5. Purring does not necessarily indicate happiness. It appears to communicate many different things. It is most often compared to smiling in humans which could indicate happiness, nervousness, an attempt not to cry, being polite, etc.
  6. The frequency of purring is healing for both cats and humans. This frequency stimulates bones and other tissues to regenerate and repair themselves. Think about that next time you are sick and your cat lays on you and purrs. 🙂
  7. Domestic cats develop special purrs to manipulate their owners into feeding them. These purrs are of higher frequency and include a bit of a cry; They are similar to those of a crying human baby.
  8. Often cats will stop purring if they hear running water. This is a trick used by veterinarians who need the cat to stop purring long enough to hear their heart and lungs.
  9. Female cats will purr while giving birth. The meaning of this purring is not totally understood.
  10. Since cats are born blind and deaf, their mother uses purring to let the newborns know where she is at.

  1. I didn’t know a lot of that! I did know that they can also purr when they are nervous.
    Next time I am sick I’ll be sure to grab one of the cats and have them sleep with me! 🙂
