Why Do Cats Purr?

Purring is one of the most distinctive and endearing sounds of a cat. It’s a sound that many cat owners find calming and soothing, but what exactly does it mean when a cat purrs? In this article, we’ll explore the reasons why cats purr and what their purring behavior can tell us about their emotional state.

What is Purring?

Purring is a low, continuous hum or buzz that a cat makes when they’re relaxed and content. It’s thought that cats have a muscle in their larynx (voice box) that vibrates when they breathe in and out, causing the purring sound. The sound is created by the movement of air past the vocal cords, which are located in the larynx.

Why Do Cats Purr?

1. To communicate with humans and other cats: Purring is thought to be a way for cats to communicate with their owners and other cats. It’s often used as a way to signal that they’re relaxed and happy, and to solicit attention or affection from their owners. When a cat rubs against a person, they may start to purr as a way of saying “I’m happy and I trust you.”

2. To self-soothe: Purring may also serve as a way for cats to self-soothe and calm themselves down in stressful situations. This is why many cats will purr when they’re in pain or feeling anxious, as the sound of their own purring may help to soothe them and reduce their stress levels.

3. To heal themselves: Some research suggests that the vibrations produced by a cat’s purring may have therapeutic benefits for the cat. The low frequency vibrations produced by a cat’s purring are thought to stimulate bone growth and promote tissue regeneration, which may help cats to heal from injuries more quickly.

Can Cats Purr When They’re Not Happy?

Yes, cats can purr when they’re not happy. Purring is not always a sign that a cat is happy or content. Some cats may purr when they’re in pain or feeling anxious, as a way to self-soothe and calm themselves down. In these cases, purring is more of a survival mechanism than a sign of happiness.


In conclusion, purring is a complex and fascinating behavior in cats that has multiple functions. Whether they’re communicating with their owners, self-soothing, or healing themselves, purring is an important part of a cat’s emotional and physical well-being. So, the next time your cat starts to purr, take a moment to appreciate this special and unique aspect of their personality.
