Why cats urrica
Usually the range of hrying cats is 25 dB. But in 2015, Merlin’s homemade cat, living in the UK, mumbled 67.8 dB and got into the Guinness Book of Records as the most loud cat. The sound published by them easily dries television programs and even a dishwasher. But what makes cat purr?
It is common that the rumbling of cats – Faithful sign of good mood. And what they need for happiness? Eat and lie on the knees from the owner so that he scratched behind the ear, stroked. But the pleasure is not at all the only reason. So why cats Murchant?
The rumbling of cats is different. With it, adult individuals, for example, resemble the owners of dinner
Kittens begin to publish sound aged two or three days, and for them it is a way to communicate. So the mother finds his cub and understands that it is time to feed them.
In 2009, scientists from Sussex University suggested that the rumbling of cats is different. And with it adults, for example, resemble the owners of dinner. To conduct a study of Dr. Karen McComb, which led the work, pushed her own cat pepo. He won the hostess persistent purr, but it was worth it to fill the bowl with food, fell silent.
The woman gained volunteers and asked them to record the sounds that make their favorites under different circumstances, and then analyzed the reasons for the purring cats. It turned out that, demanding the attention of the owner, the cats add high frequencies into the rumbling, and this sound is not at all like the one that eats an animal when stroking. He is rather similar to the crying of the baby. Not to react to it impossible.
There are other reasons why cats cut. For example, there are sounds that the animal publishes, having experienced stress or being near the sick-sorfish or owner. It’s not quite similar to purr. And the cat urchit in this case is not at all for the sake of moral support. American scientist Elizabeth von Muggeentailer noticed that not only domestic cats, but also lions, cheetahs, jaguars and other representatives of the Feline family. She examined the purring cats 44 species and found that the sound they published distributed in the range from 20 to 140 Hz. And vibrations in such a range have the therapeutic effect.
Frequencies in the range of 25-50 Hz are well helped for bone fractures, and the restoration of tissues contributes frequencies of about 100 Hz. Presumably, after stress, the cat purries precisely for this reason: heals itself, rejuvenating fabrics. Thus, Elizabeth von Muggeentaler concluded that the cat’s rumbling helps to self-defense, and this gives a considerable advantage in the fight for survival. By the way, washing – also the medical process. And ritual. Read more why cats wash the cats, we disassembled in our material.
Strengthening bones Vibration needs cats not only for treating injuries, but also because they sleep for 16-18 hours a day, and excessive immobility is harmful to health
Get a little and owners. Moreover, it has long been noticed that communication with cats helps to remove psychological stress and stress. But scientists from the University of Minnesota proved that the therapeutic effect provided by them is much more serious. Cats Murchat and help to recover their owners. Under the leadership of Adnan Kureshi, a group of doctors for ten years watched the health of 4435 Americans aged from 30 to 75 years. 2435 had cats, and in 2000 – No.
As a result, scientists noticed that catchers risk die from a heart attack by 30% less than "single". So the therapy of Murlykanya is gaining popularity around the world not by chance. Here is another answer to the question why riches cats.
And scientists of the University of California in Davis even proposed to use purring at 25 Hz for the speedy restoration of the musculoskeletal activity of astronauts, which long ago spent in weightlessness. At the same time, they relied on the theory that the strengthening of bones vibration needs cats not only for treating injuries, but also because they sleep for 16-18 hours a day, and excessive immobility is harmful to health.
It seems with why cats rush, we figured out. But how do they do it? It’s not known. Special organ for purring they have no.
American Professor and Popularizer Science Kurt Stader, like most other scientists, believes that the muscles of the larynge. Between the base of the skull and the basis of the language are thinly associated sublapping bones. When the muscles near the voice ligaments are reduced, those vibrate and we are heard by "Moore". And run the mechanism of electrical impulses arising in the cerebral cortex. They go to the muscles located near the voice ligaments and make them shrink them. By the way, you know why cats shine?
