Why Does My Cat Purr So Loud?

Case in point: Usually when cats purr loudly, we can assume that they are very happy and content. Similar to humans when cats grow old it’s their purr will deepen and increase in loudness. While often a “Loud” purr indicates happiness sometimes it might indicate that your cat is stressed or trying to heal.

When I first got my cat, Meowise, I thought he was one of those cats who would only purr if he wants to be petted. But after a while, I found out his purring is more than just a sign of affection. He purrs when he’s happy and content. 😸 He also purrs when he’s bored or anxious.
You might find this hard to believe but even cats can suffer from anxiety.

While purring is a natural and commonplace sound among house cats, it can be a bit perplexing to humans.

To be honest, since cats have their own personality the reason for the purr will differ from cat to cat. However, we have listed down some reasons why your cat may be purring so loudly.

Why Does My Cat Purr So Loud? Here are the reasons

Your Cat has a Deep Purr

Simply put, your cat’s voice is deeper. In other words, your cat is made to purr loudly. When compared with other cats if you feel like your cat’s normal meows, purrs are always louder than another cat the conclusion is that your cat has a deep purr, unique purr that’s why he is purring so loudly.

Inherently, the cat’s voice is not necessarily lower or deeper. But because of the shape of the cat’s chest when it purrs, the sound of purring tends to be louder than other cats.
The sound that cats make when they purr is soft and soothing. It makes you feel safe and secure. Cats are known to make this noise when they are in a very relaxed state, like when they are sleeping or cuddling with you.

Your Cat is very very very Happy.😻

Cats purr loudly show that they are very happy. They use it to show their contentment. In the feline world, Purring is a very common way to identify they are happy. Even Lions, tigers, and panthers do that!

Cats often purr when they’re relaxed, satisfied, or feeling loved. This is the same sound that they make when nursing their kittens or grooming each other.

That’s why often cats purr loudly when we are petting them. They feel the love and affection.

If we take my cat meowise as an example, he always purrs whenever I cuddle with him.

Your Cat is Growing.

A cat’s purr can vary depending on its size. Kittens are known to begin purring a few days after birth in order to bond with their companions and their mothers.

Their vocal cords are not fully developed and they are small enough that their purrs may sound softer and high-pitched. (Like a kid). As cats mature in size, they will gain more ability and space to make louder, more powerful purring noises.

Cats’ bodies change as they age, and naturally, their purrs will change as well. This is something you can observe over time unless there is a long period of time between having a kitten and becoming an adult.

If your cat gains weight, its purr may become louder because your cat’s size is changing.

Your Cat Is Trying To Soothe You

In addition to expressing their happiness, purring is also used to soothe other animals. Cats are known to lie on top of each other and purr to soothe their fellow animals.

They may also notice that one of their companions is sick, and they will use this method to help them heal. This behavior has gone beyond their furry friends and is now an act of self-care and an attempt to help those around them.

If you are feeling particularly stressed, your cat may start purring closer to you than usual in an effort to soothe you. Studies have shown that a cat’s purring can help lower blood pressure and encourage healing after an injury or illness.

If a fracture occurs, regular purring by a cat can stimulate bone growth.

Your Cat is trying to heal himself

If a cat snores, it releases endorphins, which reduce pain and have a stress-relieving effect. The release of endorphins helps relax them and reduces the level of pain they may feel.

When they are injured, snoring can help them relax their muscles and promote wound healing. They may also be battling an illness and want to use the sound of snoring to revive themselves.

Their snoring may be more pronounced than usual because they have a respiratory disease that can affect their snoring. They may also be suffering from hardship and their purring is louder to help heal the disease.

Some old Research Ideas on Cat Purring as a mating call.

In 1925, an article titled “Why do cats purr?” appeared in the journal Science. Written by two men (one of whom was Charles Seligman), the authors posited that it was all about mating. They cited as proof a study performed by Lorenz Stern and Hans Hagenbeck in 1908 that found that female domestic cats vocalize more often when they are ovulating, which corresponds to the same time period on a cat’s birthday.


“The question remains,” the article said, “why do cats purr?”


And here’s their answer:


“The following reasons have been suggested as motives for animal (especially feline) vocalization. The first one is that it helps to produce a certain sound that is attractive to the opposite sex. Animals which communicate with the opposite sex outside of the mother or who can mate when in adverse conditions, frequently make sounds which are attractive to them.”


In other words: cats know that it’s advantageous to use this sound when mated females are around.
Needless to say, this explanation is still debated today; some couples of cat owners have argued that their cats do not purr to attract a mate, but instead they purr when they’re happy or content.
But regardless of the cat’s intentions, it’s important to note that even though cats don’t purr for mating purposes, they most likely do purr just because it feels good.


As mentioned earlier, there are a number of theories on why this noise feels so good for humans. While one study found that cat owners were more likely than pet owners without cats to claim that the animal makes a “lullaby” sound (i.e. a soothing sound), others have proposed that humans experience a feeling of comfort or well-being when they hear cats purring.


One reason for this may be that this particular noise is somewhat reminiscent of the steady, rhythmic noise made by the mother during nursing. As an infant, it was thought that exposure to such sounds helps humans grow up with a sense of security and well-being—and we know now that these are some of the same endorphins released when the mother is breastfeeding.


Researchers have gone on to study why cats purr, specifically. The most recent study looked into whether or not cats can control when and how they purr.

Why do cats purr loudly at night?

Cats also purr much more often at night than during the day. In fact, cats can purr as many as 150 times per night, although this is usually less in domestic cats than in their wild relatives. Cats also purr when resting after a large meal. The quality of the sound may reduce if they have recently been sick or are nervous.


The reason why cats purr at night has been classified under the name “empathy hypothesis”. This states that the frequency of purring lowers our blood pressure and reduces stress, which makes us feel safe and calm. Since cats are more active at night, they will spend more time around their owners during this period.

The soothing sound of purring may help their owners fall asleep – especially if they have had a stressful day or are feeling anxious.


In contrast to humans, the ability to speak is not evolutionary beneficial for cats. Therefore it does not matter as much when this vocalization is used for communication purposes rather than for its therapeutic effects.

How do cats purr?

Since domesticated cats are descended from the wild cat species Felis silvestris, they share many similarities. Cats have a powerful jawstroke which is used to stimulate glands and muscles in their throat and tongue, allowing them to produce a range of sounds including hisses, mews, chirps, and even purrs.

Like dogs, they can detect the minute vibrations in vocal cords caused by our speech. Purring is a unique sound, as cats were believed to be incapable of producing this frequency. Researchers believe that purring may originate in the laryngeal muscles or the trachea.


A cat purr can convey many different feelings and emotions. It is used when a cat is happy and relaxed, and also when it shows affection for its owner (if it is one). It is also produced when cats have tense muscles due to sickness or discomfort from an injury, causing them pain. In addition, purring is produced to help deliver air to the lungs and maintain their body temperature. Cats will also purr when they are nursing kittens.


Although cats produce different sounds and noises, there are no species-specific vocalizations. Their ability to purr has even been documented in cats from other countries, such as India and Japan. In these countries, an individual cat may purr only a few times every day, or not at all – it is not necessary for them to purr all the time.

Is it normal for Cats to Purr Loud?

Loud purring is usually common in cats. Chances are your cat’s purr is loud because they feel happy and relaxed with you. Cats purr as a means of showing their love.

They may start purring loudly as soon as they notice you, or they may start purring after you have been petting them for a short while. When your pet purrs when you pet them, it is probably normal and they are trying to show you how much they appreciate you.

Even if they purr when you are not petting them, this is not necessarily a problem. Cats are extremely observant and if they sense that something is wrong with you, they may use snoring to make you feel better.

Cats live in constant fear, partly because they are hunters looking for their next prey and partly because they are afraid of being hunted.

In this covert state of anxiety they can pick up on the anxiety you are experiencing. Cats can pick up on differences in your behavior, especially when you seem to be stressed or experiencing discomfort. When they notice this, they can start purring loudly to try and soothe and make you feel better. This is completely normal.

If you are concerned that your cat’s purring is not normal, this could be other signs that something is wrong. When cats are unwell, they do purr to help heal.

Check for other signs of injury or illness to determine if the cat’s loud purring is normal. If you feel panting or see them purring when they cough, this could be a sign of a respiratory infection.

Look out for swollen eyes or noses, or if they are sneezing more often. Pay attention to how often they eat and how often they use the litter tray; if they are not following their normal routine, this could mean something is going on.

Also, have their body checked. When pets are injured or in poor health, they will go into a dark, quiet space to heal themselves.

If you observe your cat hiding more than normal, make sure you gently drag them out of the area and check their health. You can run your fingers through their fur looking for any cuts or sores Watch out for them to hesitate when you rub certain areas.

This will allow you to get close enough to them to hear their heartbeat and breathing patterns more clearly. These indicators will help you to determine if their noisy purring is regular.

Do Cats Purr Louder When They Are Happier?

If you’ve ever wondered why our cats make that adorable vibrating noise, it might be because they are happy. At least, that seems to be the consensus of a study conducted by an international team of researchers which was published in Nature this week.

Study author Dr. David Teie said, “The act of purring has sometimes been called ‘a low-intensity pleasure response akin to smiling’ and is believed to share similarities with sounds produced by humans who are emotional or content, such as laughter and crying.” He went on to say that “Our research reveals that the purr of cats may be a good indicator of feline welfare.”

The researchers think that this new information about purring can help us learn more about cat behavior. They also found that cats and kittens with higher purr frequencies are happier, more active, and less anxious than their less-purring counterparts.

Do Cats Purr Loudly When In Pain?

Cats purr in pain.

This might seem like a silly question, but it’s actually very important. Every pet, from dogs to hamsters, has a unique pattern of whines and growls, but only cats purr. While you may have thought that this was because cats are happy and content, it turns out that they also purr when in pain.

Cats around the world purr for several reasons. While a contented cat might have a purr at 100 Hertz, cats will also purr as high as 240 Hertz when stretching and even when giving birth. In fact, cats can’t stop themselves from purring.

If a cat is in pain, it’s not uncommon for them to also be unable to stop their purrs. As an animal lover you probably take any sign of injury or discomfort as a sign to rush immediately to the vet. But what if the cat is purring uncontrollably?

There’s no way that you could know how your cat is feeling, so you might think that it’s pointless to worry about this. But sometimes there is a correlation between purring and severe pain, and it could be worth knowing about.

Even though we’re basing this article on research that was carried out in China, these findings have since been confirmed by other researchers in Russia and Japan.

If you feel like your car is purring loudly because of pain take it to the vet as soon as possible.

Why Does My Cat Purr Loudly While Sleeping?

Cats are infamous for being finicky creatures who are sometimes less-than-amenable to give their owners any affection. However, even the most standoffish of the feline is usually more than happy to purr when they’re in a particular content or pleased mood.

It’s no wonder that when many cat owners wake in the morning, they’ll find their pets asleep in some unusual position with a loud purring noise coming from their mouths. If you’re still not sure what is making your pet purr, here are a few things to look at when trying to figure out why your cat is purring while sleeping.

However, the reason that they’re purring while sleeping is more than likely the fact that they’re simply happy to be in a warm place and feeling at ease. Well, that’s the theory at least. What might surprise many cat owners is that there are some cats who are actually happy to be purring in a loud way, as long as their owners don’t get annoyed by their behavior.

The ones who are probably the most insistent on purring while they’re asleep are the ones that have a more nervous or frightened nature to them. These cats may be more fixated on their owner’s noise than they are on their actual affection.

Cats also have a tendency to have a very sensitive hearing as well as extremely high metabolism rates, which means that they will tend to tire out easily when sleeping. When this happens, they’ll often stop moving around and start taking a little nap.
