Porque é que os gatos ronronam? A verdade surpreendente que poucos donos conhecem

If you have a cat, you’ve surely heard that soft, comforting sound as they sit on your lap, rest in the sun or enjoy a fuss. Purring is one of the most fascinating feline behaviours and one of the things that most piques owners’ curiosity.

But do cats only purr when they’re happy?

The answer may surprise you.

In this article, you’ll discover why cats purr, what science knows about this behaviour and how to interpret the different meanings behind this very special sound.

What exactly is purring?

Purring is a vibration produced by the muscles of a cat’s larynx and diaphragm.

This vibration creates a continuous sound that typically ranges between 25 and 150 Hz, a frequency that some studies link to tissue regeneration and physical recovery.

Although it may seem simple, purring remains one of the most intriguing phenomena in feline biology.

Reason no. 1: Your cat is happy and comfortable

This is the best-known reason.

Many cats purr when they’re:

Sitting on someone’s lap;
Being petted;
Lying comfortably;
Feeling safe;
Relaxed.

At these times, purring is a sign of well-being and contentment.

Reason no. 2: Cats also purr when they’re stressed

Here’s a fact many people don’t know.

Cats may purr when they’re:

Frightened;
Feeling anxious;
In unfamiliar surroundings;
Visiting the vet.

In these cases, purring is thought to work as a mechanism for emotional self-regulation.

It’s as if the cat is trying to calm itself down.

Reason no. 3: It may help with physical recovery

Some researchers believe that the vibrations produced by purring may help with:

Bone regeneration;
Muscle recovery;
Tissue healing;
Pain relief.

Although research is ongoing, this theory helps explain why some cats purr even when they’re ill or injured.

Reason no. 4: Communicating with humans

Cats have learned to communicate with us in surprising ways.

Some studies show that cats use a particular type of purr when they want:

Food;
Attention;
Affection;
Interaction.

This purr tends to sound slightly different and be harder for humans to ignore.

Why do kittens purr?

Kittens start purring a few days after birth.

This behaviour allows them to:

Communicate with their mother;
Show that they’re well;
Strengthen the maternal bond.

The mother also uses purring to make her kittens feel safe.

Do all cats purr?

Most domestic cats purr.

However, not all cats do so with the same frequency or intensity.

Some cats are naturally quieter, while others seem like real purring machines.

When should you be concerned?

In most cases, purring is perfectly normal.

However, if your cat starts purring excessively and shows symptoms such as:

Loss of appetite;
Lethargy;
Difficulty breathing;
Changes in behaviour;
Sudden withdrawal;

you should seek veterinary advice.

Your cat’s diet also affects their well-being

A healthy cat is more likely to display positive, balanced behaviours.

A high-quality diet helps provide:

More energy;
A strong immune system;
A shiny coat;
Good digestion;
Overall health.

That’s why choosing the right food is an essential part of ensuring a long and happy life.
