That’s really what in their body contributes to the fact that purrs purr? Are there any anatomical features, or is the magic inexplicable? At what age does the first “Mur” occur?
There are quite a lot of theories of contented rumbling: some are similar to reality, while others are questionable. But there is still no complete consensus. Scientists are still thinking about this to this day.
The mechanism of purring cats
Cats do not have any special organ responsible for purring. They purr because of the” shaking ” hyoid bones, which begin to vibrate under the influence of the oscillating vocal cords.
And now the vibration from the bones “passes” to the whole body, which is why it seems that the cat is all sniveling. You probably noticed that cats purr regardless of whether they inhale or exhale air. If meowing (however, like barking in dogs, chirping in birds, our conversation) is possible only on the exhalation, because the air coming out of the lungs and shakes the tense vocal cords, then purring is also possible on the inhale.
After all, purring is not a sound pronounced by a cat, but a vibration of the bones of the hyoid and all the muscles of the body
Why do the vocal cords begin to vibrate? But here it’s all about higher nervous activity. The brain Department gives the “command”, which begins this whole interesting, but very calming process. Surely you were wondering if lions and other wild huge cats purr? In fact-no (not like our Pets), but on the same principle, they growl so loudly and terribly that everyone around them runs away. This is due to the fact that domestic pussies (even lynx, they also purr) the bones are thin, so they easily “pick up” the vibrations of the vocal cords.
But in large kittens from the wild, these bones are thick, and even with cartilage, which is why they can not hesitate, but they take part in the” creation ” of a terrible roar.
When do cats purr?
Having understood how Pets purr, I want to find out why cats purr. In principle, it’s no secret that cats purr very loudly from pleasure, they can also soundlessly, as if “on vibration”.
If you put your hand, it feels like the cat is all shaking, vibrating. This is due to the release of the “happiness” hormones — the well-known endorphins. Under their action, the entire mechanism of purring is activated. Much less often because of fright, cats purr, but still this happens.
The first attempts to “vibrate” are noted in kittens the day after birth. Such crumbs do not know how to make any sounds other than a squeak, they have not learned to meow. And you need to tell your mother that everything is all right with them, so the crumbs growl.
This happens instinctively, often during and immediately after feeding, when the kittens are happy and full. They are happy and report it to their mother. And the mother cat purrs during feeding or playing, because it calms the kittens, makes them feel safe.
Also, purring in cats means sympathy. So they communicate with each other, as if they say that they are good and comfortable in each other’s company. If the cat is attacked, it can also “turn on the ur-ur” of its own, as if trying to show that it is not dangerous, does not pose a threat.
No matter how amazing it is, but the wounded or sick cats also purr. It would seem, what happiness do they have to purr? But it’s all about the nerve impulses that are sent back to the brain, causing the production of the same endorphins. But hormones are already analgesic (natural analgesics).
There is also an opinion that purring replaces physical activity for cats. Everyone knows that our home mustachioed Pets sleep almost all day long.
And if the animal does not run, does not jump, then the muscles weaken, up to atrophy. However, rumbling due to the constant fluctuation of the muscles keeps it in good shape.
