The Mystery Behind the Purr
One of the most endearing and mysterious traits of cats is their ability to purr. The soft, rhythmic vibrations often accompany moments of relaxation, but any cat owner knows that purring isn't reserved for just happy times. From new-born kittens snuggling up to their mothers to adult cats winding down on your lap, the purr is a constant, yet enigmatic part of feline communication. Why do cats purr? Is it purely emotional, or is there a deeper scientific explanation? In this article, we’ll explore the science, emotion, and therapeutic significance behind this fascinating feline behaviour.
The Mechanics of Purring
More than just a ‘happy-noise’, purring is a result of the cat’s laryngeal muscles rapidly contracting and relaxing as they breathe. This creates the soothing vibrations we associate with contentment. Fascinatingly, domestic cats purr at a frequency of 25 to 150 Hz—known to have calming effects on humans and even healing properties for their own bodies. It’s a form of nonverbal communication that conveys a range of emotions and intentions.
