Purring is a low-frequency sound that cats make by vibrating their larynx and diaphragm muscles when they exhale.

Purring is a unique vocalization produced by cats. It is a low, rumbling sound that occurs when the cat is content, relaxed, or happy.

The scientific definition of purring involves the vibration of muscles in a cat’s larynx and diaphragm.

When the cat inhales and exhales, air passes through the larynx muscles that are rapidly contracting and relaxing.

This results in vibrations that produce the characteristic purr sound. The frequency of these vibrations ranges from 25 to 150 Hertz.

Understanding why cats purr is an important step in understanding our feline friends better.

Cats are known for their purring sound which is often associated with happiness and contentment. However, there are several physiological reasons why cats purr.

Cats can purr at different rates and produce two different kinds of purrs. The first form is a smooth, strong vibration that’s produced by healthy cats with large vocal cords, who have deep voices.

The second form is called “bruxing” and consists of a high-pitched sound caused when the cat grinds its teeth together quickly.

Reasons For Purring

Why Do Cats Purr? 11 Stunning Reasons


Cats are fascinating creatures. They are known for their agility, independence, and of course, their ability to purr.

Purring is a unique sound that cats make when they are content or happy. The most common reason for a cat to purr is contentment or happiness.

When a cat is relaxed and comfortable, it will often start to purr.

This can happen when the cat is being petted or cuddled by its owner or when it’s lounging in a sunny spot by the window.

Purring can also occur during sleep or while eating.


One of the most prominent reasons is that purring helps cats to relax and reduce stress.

The act of purring releases endorphins, the body’s natural painkillers, which help to soothe and calm a cat’s nerves.

This is why cats often purr when they are feeling anxious or uncomfortable.

The sound of a cat’s purr is produced by the vibration of their vocal cords as air passes through them when they breathe.

When a cat is happy or content, it will often start to purr, which can be heard as a low rumbling sound coming from its throat.

However, research has found that the frequency of a cat’s purr can range from 20-140 Hertz, which falls within the therapeutic range for healing bones and soft tissues.

Cats have an extraordinary ability to heal themselves quickly after an injury or illness. Studies show that when cats experience pain or discomfort, they will often start to purr to help alleviate their symptoms.

The vibrations produced by their purring stimulate bone growth and repair soft tissue damage while also reducing inflammation and swelling.

Purring As A Form Of Communication

Mother Connection

When kittens are born, they are blind and deaf and rely on their sense of touch to navigate the world around them. So, the mother purrs to get the kitten closer.

At this stage, one of the ways they communicate with their mother is through touch and vibration. When a kitten nurses from its mother, it uses its paws to knead her belly gently.

This action stimulates milk production in the mother’s mammary glands and creates a soothing sensation for both the kitten and the mother.

As the kitten grows older, it learns to use other forms of communication such as meowing or body language; however, purring remains an essential part of its communication repertoire.

When a kitten feels safe and secure in its environment, it will often purr as a way to signal contentment or relaxation.

Ask Of Affection

Cats are known for their unique behavior, and one of the most fascinating things about them is their ability to purr.

For a long time, people have been trying to figure out why cats purr.

While it was once believed that cats only purred when they were happy, recent research has shown that cats use their purrs as a way to communicate with humans and other animals.

One of the reasons why cats purr is to ask for affection.

This can be seen as a way of asking for affection from its owner or other animals around it. Purring can be a sign that your cat wants you to pet them, play with them or simply spend some time with them.

Cats are known for being independent creatures, but they still crave attention and love from their owners.

Purring is just one way that cats communicate this need. When you hear your cat purring, it’s important to take notice and give them the attention they’re asking for.

Want Something

The sound of the purring is not just an indication of contentment; it’s also a way for the cat to get what it wants.

Purring is an excellent way for cats to manipulate humans into doing what they want. Cats often use different types of purrs depending on what they want.

For example, when a cat wants food or treats, it may use a more urgent and persistent type of purr than when it just wants attention or affection from its owner.

Moreover, some researchers suggest that cats’ ability to manipulate humans through their purring may be linked to their domestication history.

Domesticated cats are thought to have evolved this behavior as a way of communicating with humans because we respond positively to the sound of their purring.

Greeting Other Cats

Moreover, cats may also use purring to communicate with other animals around them.

When two cats meet for the first time or interact with each other in general, they may both start to purr as a way to signal non-threatening intentions towards one another.

This form of communication can help prevent aggression and promote peaceful interactions between felines.

Purring As An Expression

Cats Purr To Express Nervousness

When cats are nervous or frightened, they may purr as a way to comfort themselves.

Purring has been shown to have a calming effect on both cats and humans, releasing endorphins that help to reduce stress and anxiety.

For this reason, some experts believe that cats may use purring as a coping mechanism when faced with stressful situations such as visits to the vet or being left alone for extended periods.

Cats Purr To Express Fear

When a cat is scared or startled, its heart rate increases, and it may become more agitated or jumpy than usual.

Purring produces a low-frequency vibration that can have a soothing effect on the nervous system, helping to lower heart rate and promote relaxation.

Another reason why cats might purr when they are afraid is to signal to other animals or humans that they need help or protection.

Purring And Its Therapeutic Effects

Purring is often associated with contentment and pleasure, but it also has therapeutic effects on both cats and humans.

Research has shown that the frequency of a cat’s purr can have healing properties, including reducing stress and promoting relaxation.

One way in which cats use purring is to self-soothe when they are stressed or anxious. Purring releases endorphins in the brain, which help to reduce pain and promote feelings of calmness.

This can be especially helpful for cats that are recovering from an injury or illness, as well as those that are experiencing anxiety due to changes in their environment or routine.

Therapy For Humans

Humans can also benefit from the therapeutic effects of a cat’s purring.

Cats can also detect the moods of humans. As a loving cat, they can tend to purr to relax you.

The frequency of a cat’s purr falls within the range that has been shown to have healing properties on human minds.

Additionally, studies have found that spending time with cats can reduce stress levels and improve mood.

Purring may also have benefits beyond its physical effects. For many people, the sound of a cat’s purring is comforting and reassuring.

It provides a sense of companionship and connection, which can be especially important for individuals who live alone or are experiencing feelings of loneliness.

Moreover, the act of petting a cat while it purrs has been found to release oxytocin in humans.

Oxytocin is known as the “love hormone” because it plays an essential role in social bonding and trust-building activities.

It’s released during activities such as hugging or kissing someone we care about.

Studies have shown that oxytocin promotes feelings of happiness, reduces stress levels, lowers blood pressure and heart rate, and helps improve overall well-being.

It’s also been linked to reducing symptoms of depression and anxiety. In addition to releasing oxytocin, interacting with cats has also been found to lower cortisol levels in humans.

Cortisol is known as the “stress hormone” because it’s released by our bodies when we’re under stress or feel threatened.

High cortisol levels over prolonged periods have been linked to numerous negative health outcomes such as weakened immune systems, weight gain, high blood pressure, anxiety disorders amongst others.
