Why Do Cats Purr?
A purr is a low, steady, rumbling sound a cat makes deep in its body, buzzing about 25 to 30 times every second. Unlike a meow, which a cat pushes out only when breathing out, a purr keeps going smoothly as the cat breathes both in and out. The sound starts in the brain: it sends a signal to the tiny muscles around the voice box (the larynx), which open and close very fast, so the air flowing past them wobbles and makes the gentle rrrrr you can feel with your hand.
Most of the time a purr means a cat feels safe, warm and content — such as when it is curled on a lap or being stroked. But purring is not always a happy sign. Cats also purr when they are frightened, hurt or unwell, and scientists think this may help them stay calm and even heal. The steady vibrations fall in a range that may help keep bones and muscles strong. Understanding what a purr is, how it is made and the different feelings behind it helps children read a cat's body and treat pets more kindly.

Frequently asked questions
- Why do cats purr?
- Most cats purr when they feel safe, warm and happy, such as when resting on a lap or being petted. But they also purr when scared, hurt or unwell, which scientists think helps them stay calm and may aid healing.
- How does a cat make a purr?
- The cat's brain sends a signal to tiny muscles around its voice box (larynx). These muscles open and close very quickly — about 25 to 30 times a second — so air flowing past them vibrates and creates the rumbling purr.
- Does purring always mean a cat is happy?
- No. A purr usually means a cat is content, but cats also purr when they are anxious, injured or sick. It is best to look at the whole cat — its ears, tail and body — to understand how it really feels.
- Can a cat's purr really help it heal?
- Possibly. A purr shakes the cat's body at a steady, gentle speed, and scientists have found these vibrations may help keep bones and muscles strong and support healing, though research is still ongoing.
- What is the difference between a purr and a meow?
- A meow is a call a cat makes by pushing air out, often to get a human's attention. A purr is a soft, continuous rumble that carries on as the cat breathes both in and out.
