Cat purring is a mysterious and intriguing behavior. Most cat owners are familiar with the soothing, rhythmic rumble of their feline companion’s purr during moments of contentment. However, there is still much we don’t understand about why and how cats purr.
One particularly perplexing purring behavior is when a cat purrs with their mouth open. This open-mouthed purring can sometimes sound raspy or congested, which may cause concern for cat owners. But in fact, this type of purring is simply a natural variation.
While the reasons behind open-mouthed purring require more research, some possibilities include temperature regulation, communication, or even dental issues. Understanding why cats purr at all is still an evolving science. Current theories suggest purring may help promote healing, communicate with other cats, or express contentment.
In this blog post, we’ll explore the mysterious world of cat purring. We’ll discuss why cats purr in general, and delve into the puzzle behind open-mouthed purring specifically. Our goal is to provide cat owners with a better understanding of this captivating feline behavior.
What is Cat Purring?
Cat purring is a unique vocalization that all domestic cats make by rapidly contracting their laryngeal and diaphragmatic muscles. This results in a distinctive rumbling or vibrating sound during both inhalation and exhalation.
An average cat’s purr oscillates between 25-150 Hertz. For reference, the human voice range is 80-1100 Hertz. The low frequency of feline purring gives it that characteristic rumbling quality.
Purring often signals a cat is content, though cats may also purr when distressed to self-soothe. Common triggers for purring include:
- Being petted or stroked
- Sitting in a favorite spot or lap
- Nursing kittens
- Eating
- Grooming
There are different types of purring:
- Regular purring – The common purr while breathing in and out.
- Solicitation purring – An exaggerated purr when a cat wants something.
- Open-mouthed purring – Purring with the mouth open, indicating urgency.
Open-mouthed purring is not well understood. Some hypotheses suggest it helps cats breathe better when hurt or enables a different resonance. However more research is still needed on this unique vocalization.
Beyond Happiness: The Other Reasons Cats Purr
It’s commonly assumed that purring only signifies a happy, contented cat. However, researchers have discovered that cats also purr when they are distressed or in pain. Purring may act as a self-soothing mechanism for cats during times of duress.
Purring as Communication
Cats don’t just purr when they’re pleased. They also purr to communicate a range of needs and emotions to humans. Purring can signal an urgent request for food or care. Some cats even develop a special “solicitation purr” that contains a high-pitched cry, which humans perceive as more annoying and demanding.
Purring as Self-Comfort
When injured, sick, or giving birth, cats often purr. Kittens even purr soon after they are born. This suggests purring provides comfort and stress relief during vulnerable times. The rhythmic vibrations may soothe cats physically and emotionally when they are unwell or in pain.
Some experts theorize that the low-frequency vibrations in a cat’s purr can aid in wound healing, pain relief, and bone strengthening. However, more research is needed to confirm if purring offers physical therapeutic benefits.
Overall, evidence indicates purring serves multiple purposes for cats beyond expressing happiness. Paying attention to the context around your cat’s purring can provide insight into their well-being.
The Healing Power of Purring
Research by biologist Elizabeth von Muggenthaler has shed light on the potential healing properties of a cat’s purr. She discovered that the frequency of a domestic cat’s purr falls between 25 and 150 Hertz. These low-frequency vibrations may provide therapeutic effects for cats and humans.
Strengthening Bones
The 25-50 Hertz frequencies in a cat’s purr match those used by orthopedists to help mend fractures and strengthen bones. Exposure to these vibrations encourages bone growth by stimulating osteoblasts and inhibiting osteoclasts, the cells responsible for bone remodeling. This effect could explain why cats seem to heal quickly from injuries.
Relieving Pain
The release of endorphins brought on by purring may help relieve pain in cats. Endorphins are the body’s natural painkillers and induce feelings of pleasure and relaxation. By purring when injured or ill, cats may be self-soothing by stimulating endorphin production.
Accelerating Wound Healing
Research shows that low-frequency vibrations can have therapeutic effects on tissue regeneration. The 25-150 Hertz frequencies in a cat’s purr may stimulate healing by increasing collagen production, blood flow, and bone density around soft tissue injuries such as wounds or surgical sites.
Exposure to these vibrations has been shown to accelerate wound healing in humans. It’s possible cats’ purring provides similar benefits for their own injuries by physically stimulating the healing process.
In addition to the direct physical effects, the comfort and relaxation brought on by purring may also contribute indirectly to faster healing in cats.
While more research is still needed, these theories help explain why anecdotally cats seem to heal quickly and why their purring may have restorative properties.
Unraveling the Mystery: Why Do Cats Purr with Their Mouths Open?
One of the most puzzling cat behaviors is when they purr with their mouths open. This type of purring differs from the typical closed-mouth purring cats make when content. So why might cats purr in this unique way?
Possible Explanations
There are a few possible reasons why cats may purr with an open mouth:
- To aid breathing – Cats may open their mouths while purring to get more air if they are having any respiratory difficulty.
- Overstimulation – Excessive petting or attention can overstimulate some cats, causing them to purr with an open mouth.
- Pain or illness – Open-mouth purring may signal that a cat is in pain or feeling unwell.
- Flehmen response – Cats use this response to thoroughly analyze scents. The mouth opens to direct odors to special scent receptors.
The Flehmen Response
One widely theorized explanation is that open-mouth purring is connected to the Flehmen response. This innate response allows cats to fully process pheromones and other chemical cues. To perform the Flehmen response, a cat curls back its upper lip, opens its mouth, and inhales. This directs scents toward the vomeronasal organ in the roof of the mouth for analysis.
Some experts believe open-mouth purring may be a modified version of flehming. The cat is still utilizing the vomeronasal organ but also vocalizing its findings. More research is needed to explore this potential link.
Scientific Research
While many hypotheses exist, there is limited scientific research on this specific cat behavior. One 2015 study examined video footage of domestic cats purring, including instances of open-mouth purring. The researchers found that open-mouth purring occurred most often in cats also exhibiting signs of distress or agitation.
This suggests open-mouth purring may correlate with negative emotional states in cats. However, more studies systematically documenting this behavior are needed to pinpoint causes.
Understanding why cats purr with their mouths open remains an intriguing puzzle. Paying attention to the context around this unique purring can provide clues into a cat’s internal state. With more research, we may someday unravel the mystery behind this feline phenomenon.
The Significance of Understanding Cat Purring
Understanding why cats purr, especially with their mouths open, can provide cat owners with valuable insights into their pets’ well-being. Here are some key reasons why decoding the meaning behind different purring behaviors matters:
Improved Ability to Recognize Pain or Discomfort
Research shows that cats often purr not just when content, but also when in pain or distress. Recognizing open-mouthed purring as a potential sign of discomfort can help owners address underlying issues and provide appropriate care.
Increased Understanding of Cats’ Communications
Interpreting the nuances of cats’ vocalizations, including various purring behaviors, allows owners to better understand what their pet is communicating. This knowledge facilitates stronger bonds and care.
