Why do cats rumble and purr?

Since childhood, people are beginning to worry like a trifling problem - why do the cats rumblings? And to put it more precisely, exactly how they do it. Zoologists can tell about this. Home pets have special thin bones near the vocal cords, located between the base of the skull and the place from which the tongue grows. When an animal experiences pleasure, its brain generates impulses, which cause the muscles to contract diminishingly near these hyoid bones. Muscles are straining, then relaxing, why in the vocal chords there is a vibration that resonates in the bones echoes. Therefore, we hear such a quiet "tarah".

Among the huge family of these animals, not all are purring. Big cats - lions, tigers - growl, and they do not know how to make a rumbling: in their vocal cords there is a sublingual cartilage that produces roar, and not pleasant sounds for the human ear. The other large representatives of this species can make grunting, howling, hissing, even grunting and coughing sounds, but they do not purr. But this art is mastered by medium and small wild beasts of this family: cheetah, puma, lynx, ocelot, manul and serval. Why do they do this and what does the meaning of the cat play in this matter? Let's look at the situation when our pets are making these sounds.

In most cases, pussycat purrs when it feels good. She ate and washed. She was a little chilled, but then she warmed herself on her lap and switched on her "music box" to its full potential. She overlaid with her offspring, licked the kittens and "sings" to them a lullaby, and they, in turn, sucking milk, quietly yelp in response. Yes, in the overwhelming majority of life situations, the correct answer to the question "why cats are grumbling" will be: "Because it's good for them." Murmuring is a statement of the fact that everything is in order. Mom-cat is so informing his children that there is no cause for concern. Still blind kittens instinctively publish such sounds during feeding, showing that they are healthy and viable. A cat with contented "tarahteniye" shows his love for the owner and demands that he be ironed.

But experts-felinologists describe other cases when animals can make similar sounds. Sometimes a sick or wounded animal begins to purr, and the host mistakes these sounds as a sign that his pet has become easier. Why do cats rumble in such a life-threatening situation? They try, as we would say, "to do auto-training", to inspire yourself that nothing terrible is happening. It happens that when you meet a dominant cat, the weak starts to rumble, showing that he does not intend to get involved in a fight, that he is already surrendering and defenseless. More often than not, the principle of "do not hit the recumbent" works. And sometimes, cats, fights, being in perfect spirits, when meeting with other brethren purring, showing friendly intentions.

Sometimes a cat growls when something demands. But then this sound is louder and more persistent. By the way, the most "loud" kitty lives in the UK. The sound level of Smokey reaches almost 68 decibels, for which it is recorded in the Guinness Book of Records. It is noteworthy that the hostess of Smoky likes to keep on his knees pitomitsu, which buzzes like a working tractor. After all, scientists have proved that this normalizes blood pressure not only from pets themselves, but also from those who are nearby. Therefore, pussy is used for the therapy of nervous and easily-excited children. Even purring helps the kids relax and fall asleep.

But if the scientists found the answer to the question "why the cats are grumbling," the question "why they stop doing this when they hear the sound of running water" remains a mystery. But the fact remains: veterinarians have long noticed this feature, when they need to listen to the lungs and the heart of the animal with a stethoscope, they simply open a faucet in the washbasin in the office. "Mur-Mur" immediately stops.
