Cats purring is a fascinating and mysterious phenomenon. While it is widely believed that cats purr when they are happy and content, they also purr when they are in pain or distress. Purring is not exclusive to domestic cats, as big cats like cheetahs and cougars also purr.
The mechanics of purring involve the cat using its larynx and diaphragm muscles to create vibrations as they inhale and exhale. Despite extensive research, it is still not entirely clear how the central nervous system generates and controls these vibrations.
Early taxonomists believed that cats either purr or roar and split the family Felidae into "purrers" (subfamily Felinae) and "roarers" (subfamily Pantherinae). However, modern taxonomists believe that most cats can purr, with a few possible exceptions such as the lion, leopard, jaguar, tiger, snow leopard, and clouded leopard.
So why do cats purr? While it is possible that purring is a form of communication, it is believed to be primarily a soothing mechanism. Purring has been associated with positive social situations such as nursing, grooming, and being friendly. However, cats may also purr in stressful situations, suggesting that purring is a form of self-soothing.
Interestingly, purring frequencies have been shown to stimulate bone regeneration. This finding opens up a new area of research into the potential health benefits of purring.
In conclusion, the mystery of why cats purr remains largely unsolved. However, it is clear that purring is a complex and multifaceted phenomenon that plays an important role in the lives of cats. Whether they are communicating with their owners or simply soothing themselves, cats continue to intrigue and captivate us with their mysterious purring.
Happiness and Contentment: Cats often purr when they are happy and relaxed. This is the most common reason for purring and may occur when they are being petted, snuggled or simply enjoying their surroundings.
Communication: Cats also use purring as a means of communication with other cats, especially with their mother and kittens. Purring helps to bond mother cats with their offspring, and kittens can use purring to signal their need for attention and care.
Healing: The vibrations created by purring may have healing properties for cats. Studies suggest that the low frequency and intensity of the vibrations may help to reduce inflammation, lower stress levels and promote healing of bones, muscles and tissues.
Self-Soothing: Cats may also purr as a form of self-soothing. When they are anxious or in pain, purring can help to calm them down and provide comfort.
Hunger or Need for Attention: Some cats may purr to signal their hunger or need for attention. They may approach their owners and purr to get their attention or to request food.
Territorial Marking: Cats may also purr as a means of territorial marking. They may purr to stake their claim on a particular space or to signal to other cats that they are in charge.
Table: Frequency Range of Cat Purring
| Frequency Range | Description |
|---|---|
| 25-50 Hz | Occurs when cats are in pain or distress. |
| 50-150 Hz | Typical purring frequency range, indicating relaxation and contentment. |
| 150-400 Hz | Sounds more like a trill than a purr and may occur during play or social interactions. |
| >400 Hz | High-pitched vocalizations, such as meowing or chirping. |
Note: The frequency range of purring may vary depending on the individual cat, their age, health, and emotional state.
| Reason | Explanation |
|---|---|
| 1. Your cat is happy | Cats may purr when they are happy or content. It is their way of expressing pleasure and can occur when they are being petted or cuddled by their owner. Purring while eating or drinking may also indicate feelings of satisfaction. |
| 2. As a way for mother cats and kittens to communicate | Kittens start to purr when they are only a few days old as a way to communicate and bond with their mothers. The vibrations from a mother cat's purr can help guide the kittens to nurse, especially since they are born deaf and blind. |
| 3. Your cat is stressed | While purring is commonly associated with happiness, cats may also purr when they are stressed or anxious, such as during a visit to the vet. Purring can be a way for them to self-soothe and calm down. An anxious purr may have a slightly higher pitch and may be paired with panting or showing teeth. |
| 4. To heal themselves and relieve pain | Purring can ease pain and regulate breathing. Low-frequency vibrations produced by purring can also stimulate healing, particularly of bones and tendons. Similar vibrations have been used in humans to promote bone growth and muscle strength. |
| 5. To greet other cats | Cats may purr upon seeing another familiar cat as a way to greet them. It could be a way to let the other cat know they are friendly and approachable, and not a threat. The exact message is still unknown to scientists. |
| 6. Your cat wants something from you | Cats may produce a high-pitched, urgent purr when they want something from their human owners, like food. Humans are more likely to react to this type of purr. |
In summary, purring is a complex and multi-functional behavior in cats. It can indicate happiness, stress, healing, communication, and solicitation. Understanding the context in which your cat is purring can help you better understand their needs and preferences, leading to a happier and healthier relationship with your furry friend.
