Why does my cat purr so much when i pet him

Purring is the most common sound cats make. Yet we know less about it than meowing, chirping, chattering, hissing, and growling.

Yes, cats purr when they're content. When yours is curled up in the sun, you may hear a gentle rumble as they breathe in and out. Touch them, and you feel a little quiver. It's almost as if they are sending out waves of calm.

But you shouldn't assume that sound means your cat is in a good mood. Or that it's the only time you'll hear it. Cats purr to communicate other emotions and needs, too.

What if you pick your cat up and hold them? Do they purr because they like it -- or because they are nervous?

Although you'll never know exactly what yours is saying when they purr, research from animal experts, along with considering the situation, lets you make an informed guess.

Your cat looks relaxed: Perhaps they are on their back, eyes half-closed, tail mostly still. If they are purring, it's safe to assume they are in their happy place.

That noise is a big smile.

Some cats purr when it's mealtime. British researchers studied the sounds that house cats make when they're hungry and when food isn't on their minds. The purrs don't sound the same.

When cats purr for food, they combine their normal purr with an unpleasant cry or mew, a bit like a human baby's cry. Experts believe that we're more likely to respond to this sound. They've found that people can tell the difference between the purrs, even if they aren't cat owners.

Kittens can purr when they're only a few days old. It's probably a way to let their mothers know where they are or that they're OK.

Purring also helps a kitten bond with its mother. Mama cats use it like a lullaby.

Even though purring takes energy, many cats purr when they get hurt or are in pain. So what makes the effort worth it?

It might simply be a way for a cat to soothe itself, like a child sucks their thumb to feel better.

But some research suggests that purring actually helps cats get better faster. The low frequency of purrs causes a series of related vibrations within their body that can:

  • Heal bones and wounds
  • Build muscle and repair tendons
  • Ease breathing
  • Lessen pain and swelling

This might explain why cats are able to survive falls from high places and tend to have fewer complications after surgeries than dogs.

Cats are surprisingly vocal animals, communicating with meows, trills, hisses, growls, yelps and shrieks. But perhaps the most enchanting and mysterious noise they make is the purr. There’s something relaxing – almost hypnotic – about this unique and frankly odd animal vocalisation. But what does it mean?

Why cats purr

A cat’s purr can have a number of different meanings. Here are four reasons why your cat may be purring.

1. Cats purr because they are content

Perhaps most obviously when curled up on a human’s lap, cats may purr because they’re warm, cosy and content.

2. Cats purr to calm themselves

While it’s true that cats purr during moments of extreme relaxation, animal experts believe that cats also purr at times of great stress or pain, such as during a visit to the vet and even when giving birth.

Scientists now believe that cats purr to calm themselves down, meaning they’re just as likely to do it in a stressful or painful situation as they are when curled up in someone’s lap. The low-frequency vibrations of purring help them ease their breathing and soothe tension.

3. Purring helps with healing

Purrs do more than simply calming down your cat – scientists also believe these vibrations can help heal injuries, repair and build muscles, even act as a painkiller which might explain why injured or sick cats choose to expend valuable energy on purring. It might also explain why cats have a tendency to recover more quickly than dogs from surgery and suffer fewer complications.

4. ‘Solicitation purrs’ help your cat ensure their needs are met

Purring can also aid your cat in more direct ways. Scientists have identified a particular type of purring, known as the ‘solicitation purr’, that cats appear to use exclusively as a means of obtaining something from their owner – either affection or food.

The ‘solicitation purr’ is a cross between a meow and a purr, and is close in frequency to the sound of a crying baby – a noise we are naturally programmed to respond to.

A cat's purr could benefit humans

A cat's purr could have benefits for humans, too. A long-term study carried out by the University of Minnesota Stroke Centre found that cat owners were less likely to die from cardiovascular disease compared to non-cat-owners - and some people have suggested that exposure to purring might be part of the reason for this. 

What if my cat doesn’t purr?

Each cat purrs in a different way and at a different volume. Some cats purr in almost complete silence, and the only way to tell they are doing it is by touching their neck or throat to feel the vibration. That said, other cats don’t appear to purr at all, and, barring an injury to the vocal cords, scientists are still trying to understand why.

Feral cats are more likely to be non-purrers than domestic cats, leading to a theory that feral cat mothers discourage purring in their kittens to prevent them from attracting predators.

Scientists also note that feral cats are much less vocal than their domesticated counterparts, often only meowing and purring as kittens, and abandoning the habits during adulthood. This may be because domestic cats developed their vocal tendencies to better communicate with humans. A purring cat may solicit petting or treats, and a meowing cat may get dinner faster than a quieter companion.

Cats don’t have the same level of facial expression as dogs, are typically quieter, and their actions might be more difficult to decipher—but that doesn’t make the feline mystique impenetrable.

Pay attention to your pet’s vocalizations, body postures, and daily activities to gain a deeper understanding of them.

When cats are in a peaceful atmosphere, they will purr, sending off waves of tranquilly. This can also happen when you pet them, indicating that your feline companion is pleased or friendly. Cats, on the other hand, purr to express a variety of emotions and wants.

You may grow so sensitive to your kitty’s personality and habits over time that you’re able to detect minor mood shifts and even spot health issues before they manifest physically.

If your cat purrs while being caressed and handled in these places, we may assume it is comfortable and happy.

Mother cats use purring to entice their kittens closer to keep them warm and safe, or when it’s mealtime, because kittens can’t orient themselves. Their gentle noises can also be used as a cradle song for their kittens.

3. Sign of Distress

Purring does not necessarily imply that your cat is a joyful ball of fluff rolling around on its back, sending subtle rasp vibrations out for your attention. When a cat is disturbed or nervous, he or she purrs.

They may be anxious as a result of unexpected changes in their home, such as the addition of a new pet, a new human family member, or even home remodelling.

They also produce similar sounds when they are scared or in need of assistance. Purrs can assist your cat relax during a stressful situation, such as giving birth.

Purrs have the power to make your cat feel better, promote healing, and relieve pain.

5. Overstimulated

Because they are overstimulated, our felines may purr when you brush them. Keep an eye out for abrasive, loud purring, biting, and other aggressive behaviours.

Cats are sensitive to touch, and your frequent petting might cause them to become overstimulated. They may accept your petting, but it’s better to leave them when their purring gets agitated and loud.

Take a look at these indications that your cat is overstimulated:

  • The tail is pounding or swishing
  • Ears that have been lowered or flattened
  • Snarling or hissing
  • Attempting to flee
  • The muscles of the body are tight.

  • While you’re caressing her, she’s squirming.
  • Claws protrude from the body.
  • Displaying various forms of aggression
