Interesting Behaviour : Why Do Cats Purr?

Cat’s purr for a variety of reasons. It is generally believed that they purr when they are content and relaxed, expressing happiness and comfort. Purring also serves as a means of communication between mother cats and their kittens, promoting bonding and reassurance. Additionally, purring may have healing properties, help cats calm themselves in stressful situations, and serve as a way to gain attention and affection from humans. Although the exact reasons may vary, purring is an attractive behaviour that heightens the attractiveness of our feline friends.

The Science Behind The Purr

Purr is a slow, rumbling sound produced by cats, usually through vibration of their larynxes and vocal cords. It is a soft, continuous and rhythmic sound that can vary in intensity and pitch. Purring is often associated with contentment, relaxation, and emotional well-being in cats, although it may also occur in other situations such as when they are seeking attention or in distress. The sound of Purr is a unique feature of cats and an important part of their communication repertoire.

Physical System Involved

1             Vibration in the larynx and diaphragm

Cats purr results from vibrations in both the larynx (voice box) and the diaphragm. When a cat purrs, the muscles of the larynx open and close the space between the vocal folds, causing them to vibrate. These vibrations produce the characteristic meowing sound.

In addition to the larynx, the diaphragm, which is a large muscle located between the chest and abdominal cavity, also plays a role in purging. As the cat breathes in and out, the diaphragm contracts and relaxes, creating a rhythmic movement. This motion contributes to the vibrations that are felt and heard during the purr.

2             Frequency range and intensity of the purr

Frequency Range: The normal meow frequency of domestic cats falls within the range of 25 to 150 hertz (Hz). However, some cats may meow outside this range, at either higher or lower frequencies.

Intensity: The intensity of the meow can also vary among cats. Some cats have soft and subtle purrs, while others have more robust and resonant purrs that can be felt or heard from a distance.

Different Purposes of Purring

Expressing contentment and relaxation

1             Purring during a cuddle session

When cats are sitting next to their owners or are being gently petted and caressed, they may begin to purr as a sign of contentment, relaxation, and pleasure. It is their way of expressing their comfort and satisfaction at the moment.

Hugging provides physical closeness and social contact, which is important for the relationship between cats and their human caretakers. The rhythmic vibrations of the purr not only provide a soothing and calming effect for the cat, but also create a pleasurable experience for the person involved in the cuddling session.

For cat owners, hearing their feline friend meow during a cuddle session can be a heartwarming and rewarding experience. It enhances the bond and strengthens the emotional connection between a cat and their human companion. Cuddle sessions provide a mutual source of comfort, affection and pleasure, creating a harmonious and memorable moment between cats and their owners.

2             Purring as a sign of trust and comfort

Meowing in cats is often considered a sign of trust and comfort. When a cat purrs in the presence of its human caretaker, it indicates that it feels safe and comfortable in that person’s company.

Cats are naturally alert animals, and their ability to purr is believed to have evolved as a way of communicating their contentment and establishing a sense of security. Meowing can occur in a variety of situations where a cat feels comfortable and trusts its environment and the people around it.

When a cat purrs as a sign of trust, it indicates that they feel relaxed and perceive their surroundings as non-threatening. This can be seen when a cat approaches its caregiver, rubs their legs, or sits down in their presence while they purr. The rhythmic vibration emitted during a purr is not only a vocalization but also a physical expression of their emotional state.

Purring serves as a form of communication from the cat to their human companion, expressing their trust and satisfaction. This is a way for cats to show that they feel safe, loved and valued in a relationship with their caretaker. In response, humans often interpret the meow as a positive affirmation and feel a sense of connection and reassurance from their feline friend.

Understanding the meow as a sign of trust and comfort helps deepen the connection between cats and humans. This fosters a nurturing environment where the cats can feel safe and supported, ultimately strengthening the relationship and creating a harmonious companionship based on mutual trust and affection.

FAQs About Purring

A            Can all cat purr?

No, not all cats have the ability to meow. Meowing is primarily observed in domestic cats (Felis catus) and some wild cat species, but is not universal throughout the felid family. Big cats such as lions, tigers and leopards do not have the necessary anatomical structure to purr. Instead, they make other sounds such as roars, grunts, or guffaws.

The purr is a unique feature found in cat species that can purr. However, it’s worth noting that not even all individual cats of those species can meow. Some cats may not exhibit meowing behaviour due to factors such as genetics, health conditions or individual temperament.

B             What if the cat does not purr?

If the cat does not growl, this is not a cause for concern. Although Purring is a normal behavior in many cats, not all cats purr, and it does not necessarily indicate a problem with their health or well-being. Here are some reasons why a cat does not purr:

1. Individual differences: Just as humans differ in personality and behavior, cats also exhibit individual differences in their behavior. In some cats, the tendency to meow may be less pronounced or less frequent. Every cat has its own unique way of expressing contentment and seeking comfort.

2. Breed Differences: Some cat breeds are less likely to meow than others. For example, breeds such as the Siamese or Oriental Shorthair are known to be more vocal and may have different vocalization patterns instead of purrs. It is important to understand that meowing is not the only indicator of a cat’s happiness or well-being.

3. Physical factors: Some cats may have physical limitations that make it difficult or impossible to purr. Certain health conditions, injuries, or physical abnormalities can affect a cat’s ability to produce a meowing sound. If you suspect that your cat’s inability to purr is due to a physical problem, it is best to consult a veterinarian for a thorough examination.

4. Environmental factors: Cats’ purring behavior can be affected by their environment and the specific circumstances they are in. If a cat is feeling stressed, anxious or uncomfortable, they may not meow so easily. Creating a calm and nurturing environment for the cat can help them feel more secure and may be more likely to purr.

5. Other communication methods: Cats have various ways of communicating their feelings and needs, beyond meowing. They may use body language, vocalizations, kneading, or other behaviors to express themselves. It is essential to observe your cat’s overall behavior and consider other forms of communication they may use to assess their well-being.

If your cat is displaying other signs of trouble, such as loss of appetite, lethargy, or a change in behavior, it is worth consulting a veterinarian to rule out any underlying health issues. Otherwise, if your cat appears healthy and exhibits other signs of contentment, not meowing should not be a major cause for concern. Remember, each cat is unique, and their individual behavior may vary.

C             Are there any health concerns associated with purring?

In general, meowing is not associated with significant health concerns in cats. It is a natural behavior that usually indicates a desire for gratification, relaxation, or social interaction. However, there are some situations where meowing may be a sign of an underlying health problem or may require veterinary care. Here are some examples to be aware of:

1. Meows in pain: While meowing is often associated with positive emotions, some cats may also meow when they are in pain or distress. This can make it challenging to identify when a cat is experiencing discomfort. If your cat is meowing excessively or is accompanied by other signs of distress such as hiding, loss of appetite or a change in behavior, it is important to consult a veterinarian to rule out any underlying health issues.

2. Respiratory problems: Cats with respiratory conditions such as upper respiratory infections or asthma may exhibit abnormal meowing patterns or may have difficulty meowing. If you notice a change in your cat’s purring behavior, such as wheezing, hoarseness, or a struggle to produce purr vibrations, this may be a sign of respiratory problems and should be evaluated by a veterinarian.

3. Hyperthyroidism: Hyperthyroidism is a common endocrine disorder in cats, characterized by an overactive thyroid gland. Some cats suffering from hyperthyroidism may meow excessively or display a persistent meow-like sound, which can be attributed to increased heart rate and restlessness. If your cat’s meowing becomes persistent and unusual, especially along with weight loss, increased thirst and hyperactivity, it is necessary to seek veterinary care.

4. Injuries or painful conditions: Cats may meow as a self-soothing mechanism, even when they are injured or in pain. Purring can release endorphins, which can provide temporary relief from discomfort. If your cat has been involved in an accident, is suffering from trauma, or is exhibiting signs of pain such as limping, reluctance to walk, or changes in appetite, it is important to have them evaluated by a veterinarian.

It is important to monitor your cat’s overall behavior, appetite and any changes in its purring pattern. If you are concerned about your cat’s health or notice any unusual or persistent changes in his purring behavior, it is best to consult a veterinarian for proper evaluation and guidance.

D            Can humans mimic meowing or communicate with cats through meowing?

While humans cannot produce the exact same meowing sound as cats, some individuals can mimic a meow-like sound by producing a soft and rhythmic sound. This mimicry is not a true meow, but may serve as a way of communicating with cats in a soothing manner. However, it’s important to note that cats are more likely to respond to other forms of communication that they understand, such as body language and vocal cues specific to human speech.

Cats primarily use meowing as a means of communication among themselves and with their fellow mates. It is a sound that expresses satisfaction, relaxation, and sometimes a desire for social interaction. While humans cannot communicate with cats through meowing in the same way, they can use other forms of communication to interact effectively with their feline friends.


In conclusion, purring is a unique behavior in cats that serves multiple purposes. It is a soothing mechanism that helps cats relax and heal. Purring is a sign of trust, comfort, and companionship, enhancing the bond between cats and humans. Scientific studies have shown the therapeutic effects of purring on both cats and humans. While humans cannot mimic purring exactly, they can communicate with cats through body language, vocalization, and play. Purring is a fascinating and endearing aspect of feline behavior that brings joy and benefits to both cats and humans
