Have you ever wondered why cats purr so contentedly? Let’s discover together! While there are many good guesses, one thing we all know is that the soothing sound is more than just a sign of happiness. Most people observe that cats purr when they’re pleased and feeling good. However, cats also purr when they are hungry, injured, or frightened. In this blog, we’ll delve deeper into why cats purr, exploring both the causes and the fascinating reasons behind this behaviour.
How Do Cats Purr?
Cats purr through their larynx and diaphragm muscles both as they inhale and exhale, and a neural oscillator in the brain. As the cat breathes, air moves through the vibrating muscles and creates a purr sound. This happens during both exhaling and inhaling. These rapid muscle movements cause vibrations throughout the cat’s body, which can only be felt while the cat is purring.
A typical cat’s purr falls within the range of 25 to 150 hertz (Hz). Most cats purr within the same frequency range, but some cats have slight variations due to factors like age, health, and mood.
