Why is my cat purring? From being stressed to felling hungry - here are all the different types of purr
You might be surprised to hear that cats have a variety of different purrs.
Most cat owners assume purring is simple: your cat is happy, comfy and living their best life.
But, typically of our feline friends, the truth is far more chaotic, adorable and occasionally manipulative. according to Purr and Meow’s resident vet
Dr Linda Simon, the resident vet at Purr and Meow, has revealed how complex the purr actually is.

She explained: “Purring is a cat’s communication toolkit, they use it for joy, stress, healing, bonding…and sometimes to get exactly what they want.
“Don’t assume a purr always means happiness. Look at the whole picture, their body language, environment and behaviour. Cats are subtle, but their purrs tell you more than you think.”
Here’s what Dr Linda Simon thinks you need to know about the surprising secrets behind your cat's purr.
What are the reasons for a cat purring?
There are a few different reasons a cat may purr, namely:
They’re happy
Yes, cats purr when they’re relaxed, cosy and living their best loaf‑life. This is the classic purr: soft, steady, and usually accompanied by slow blinks and biscuit‑making paws.
They’re stressed (and pretending they’re fine)
Cats often purr when they’re anxious - at the vets, during fireworks, or when something in the house changes.
Purring releases endorphins. It’s a self‑soothing behaviour, like humans humming or taking deep breaths.
So that “I’m totally fine” purr might actually be your cat trying to calm themselves down.
They’re healing themselves
This one sounds unbelievable, but science backs it up. Cats purr at a frequency between 25–150 Hz, which research suggests can help:
- Reduce swelling
- Promote tissue repair
- Strengthen bones
It’s like they’re giving themselves a tiny internal massage.
They want food - immediately
This is the purr that hits differently: louder, higher‑pitched and impossible to ignore.
It’s called the solicitation purr, and it’s designed to make humans respond quickly.
Cats learn that certain purrs get results. It’s deliberate. They’re very clever.
They’re speaking ‘baby language’
Kittens start purring at just a few days old. They use it to tell mum: “I’m here”, “I’m safe”, or “I’m hungry”.
Mother cats purr back to guide their kittens, who are born blind and deaf. It’s basically their first language.
How can I identify the different types of purr?
Here’s how to tell what your cat’s purr really means
- Soft, steady purr: relaxed, cosy, happy
- Loud, urgent purr: “Dinner. Now.”
- Fast, shaky purr: nervous or seeking comfort
- Purring while ill or injured: self‑soothing or healing - worth a vet check
How do cats actually make the purring noise?
Tiny muscles in the larynx twitch 20–30 times per second, vibrating the vocal cords as the cat breathes in and out.
It’s involuntary - once the brain sends the signal, the body takes over.
