Cat Wellness: The Science Behind Purring

For cat lovers, the purr is an endearing trait we all find irresistible. But what exactly a purr is and why cats do it remains a bit of a mystery. Science tells us purring is good for a cat's health, and perhaps for human health, too. Here are some of the amazing benefits behind a purr and how it can improve a cat's well-being.

Eliminates stress

In stressful situations, kitty cats purr to calm sensitive emotions and soothe frazzled nerves. It's believed the rhythmic vibrations from a purr send signals to a cat's brain triggering a wave of body relaxation.

Repairs tissue

Purrs have an audible frequency range of 20 to 200 megahertz. This frequency helps body tissue to regenerate and stimulates bones, keeping them strong and less prone to breakage. "Purr therapy" is currently being tested on astronauts as a preventive measure against bone density loss while living in space.

Sign of contentment

Scientists have different theories about how a purr is produced, but all agree a purr is most commonly a sign of contentment. When a cat purrs, air moves between the vocal cords independently of air passageways. This ability enables a happy cat to keep purring indefinitely.

Health checker

There are instances when a purr can indicate an illness or injury. Stay on top of your cat's health by identifying what made your kitty purr in the first place. Knowing when a purr is the sign of a happy cat or when it's time to call the vet can make a big difference in your cat's health.

Purring is a mysterious trait all domestic cats share. A purr can do many things, from bone repair to decompressing stress. While scientists continue to unravel a purr's true purpose, cats are happy to dole them out to the delight of every pet parent.
