Chinese people keep cats. There are reliable documents recorded about 3,000 years ago, when cats were already called "cats".

Of course, 3,000 years ago is only the earliest documented record found so far, and our history of raising cats may be even earlier.

More importantly, in the next 3,000 years, cats have been a symbol of mystery, both in China and around the world. To this day, various myths about cats are still spread among the people. "Mystery Story".

So everything about cats is mysterious, even the purring sound made by cats is mysterious, because it has at least three functions.

Popular Science: Why do cats purr

Zoology provides a scientific explanation for cats purring.

Cats purr because there is an organ called a "neural oscillator" in the cat's body. The neural oscillator sends out neural signals after sensing the surrounding environment, the cat's mood, and the cat's physical condition.

After receiving the nerve signal from the "neural oscillator", the glottis organ will quickly open and close, causing a change in valve air pressure. This air pressure change resonates with the cat's breathing, thus generating air resonance, and the cat will Produces a purring sound.

The scientific explanation is somewhat obscure, but to sum it up in plain English: after the cat’s brain senses the external environment, emotions, and physical state, as long as certain conditions are met, it will send nerve signals to the cat’s throat. This causes the cat to purr.

Meaning 1 of a cat’s purring: Happy

There are many examples of cats purring in life. For example, when the cat is petted by a cat, if the technique is done properly, the cat will purr.

As if to say: "It's so comfortable, come on", the poop collectors who hear the cat purring will also be happy.

Another example is when a cat is basking in the sun and feeling comfortable, it will also purr.

Therefore, poop scrapers have discovered that cats will purr as long as they are happy, joyful, or even comfortable. Cats that have just been brought home will never purr when they are not familiar with the new home environment.

Therefore, most people think that a cat’s purr means to express happiness, but in fact, a cat’s purr is more than just an expression of happiness.

Meaning 2 of a cat’s purring: Prayer

In addition to expressing happiness and joy, a cat’s purring also has a second meaning: prayer.

When the cat has various needs, the neural oscillator will also send out neural signals, causing the cat to purr.

For example, when a cat is eating cat food and finds that the cat food is gone, it may scream at the scavenger. At this time, the cat will also purr, which is praying for food.

When the cat just wakes up, stretches and takes the initiative to look for the scavenger, the cat will purr and meow at the scavenger. At this time, the cat is praying and scavenging. Official communication, or praying for a touch.

Therefore, the second meaning of a cat purring is that the cat is expressing its appeal!

Cat purring means three things: Healing

In addition to expressing pleasure and prayer, a cat’s purring also has the most important function: healing.

When a cat is sick, due to the pain and torture, the cat will also purr. The purr at this time is not to express pleasure and prayer, but to express pain. This is the same as when humans are injured. , moaning is a truth.

But unlike human moans, which are only used to express painful emotions, a cat’s purring, in addition to expressing painful emotions, also has a certain self-healing function.

In addition to healing yourself, you can also heal your master

More importantly, a cat’s purring can not only heal itself, but also its owner. A foreign animal behavior research institution found that cats’ purring can relieve stress, regulate breathing, relieve fatigue, and even improve the heart rate of humans. health effects.

This is also the reason why cat owners generally live longer and healthier than people who don’t own cats.

So a cat’s purring is more than just an expression of happiness. In daily life, if your cat purrs to you, you should consider three aspects.

First: Cats purr when they are happy.

Second: The cat is praying for something from its owner, such as food or communication.

Third: The cat is sick.

Instead of like before, as long as the cat purrs, you think the cat is happy.

Of course, if you have a cat, remember to interact more with the cat. If the cat is happy, the cat will purr more. The more the cat purrs, the healthier and longer the owner will be.
