Cats are popular Pets in the world
Cats, along with dogs, are some of the most popular Pets in the world. According to statistics, today there are more than 600 million , and the number of their species has already exceeded 200. Probably, in the world there is no one who has not heard the warm and calm purring of these furry creatures. But do you know what your purpose is and how they make these sounds? The answer to this question decided to give scientists from the UK the results of their research were published in scientific publication .
It is worth to emphasize that cats are distinctively social animals. This means that they actively interact with each other and willing to communicate with people. For this they use a variety of sounds, body movements and pheromones — emitted by the body substances necessary for chemical communication between individuals of the same species.
How to communicate with cats?
One of the most commonly used sounds in cats is the purr. According to scientists, the frequency of sound waves varies from 20 to 30 Hz and depends on the surrounding circumstances. For example, if you want to eat animals purr with a certain frequency, and when they're just quiet — completely different. The researchers also claim that cat's vibrations help to heal bones and relieve pain.
Only now convincing scientific explanation for the curative properties of cat's purring yet. Perhaps the pain relief is due to the fact that cats usually lie on the affected area and keep him warm with their body temperature, which is usually equal to 38-39 degrees Celsius. But the ability of cats to treat depression and can be explained by the fact that spending time with animals distracts from the obsessive thoughts and helps at least to get away from problems.
Interesting fact — while purring in a cat is impossible to listen to breathing and heartbeat.
Despite the lack of convincing scientific evidence of the healing abilities of cats, the world is a very popular method of therapy called felinoterapiya. First treatment for cats was applied in the eighteenth century, outside the walls of a hospital in England. Besides the fact that cats "heal" people with their purring and warmth, some doctors saw the benefit in the so-called "milk step". This term refers to the slow shuffling of cats in a certain place — the kind of massage they do his mother's stomach as a child, that the Breasts give more milk.
It is Also known that purring helps cats heal their own wounds. It is believed that the vibrations stimulate the brain into producing the hormones responsible for pain relief, relaxation and tissue repair. Once scientists from the California city of Davis has suggested that this property purring helps the cat to maintain bone health, which can easily be weakened due to sedentary lifestyle furry creatures.
Some cats sleep for 16-18 hours a day.
What body the purr of a cat?
Throughout the long years of research, scientists have not been able to detect in cats "purring machine". There is an assumption that for the publication of vibrating sounds are responsible arising in the cerebral cortex the electrical impulses that cause to decrease the vocal cords. If so, we can say that the source of the purring sound is between the base of the skull and base of the tongue. The purring sound is made through the mouth and nose and distributed throughout the body.
