Something very interesting about purring is that only felines can do it in the wild. This sound represents the vibration of the animal when inhaling and exhaling, but in a totally unique way when compared to other animals.
Within an evolutionary perspective, we understand that the catsdeveloped this skill for survival.
In this case, scientists noticed that cats are born blind and deaf, so they would not be able to connect with the outside world if it weren't for their purring. More precisely, cats are able to identify their mother by the purring she emits and thus get closer to her and recognize her in the first days of life.
Furthermore, it is worth considering that, in the context of the jungle or nature, cats need to flee from predators just like everyone else. In a way, purring protects them, since it is possible to establish communication from the cubwith its mother in an almost inaudible way to other predators.
People these days have simply embraced the understanding that cats only purr when they are happy or comfortable. However, this statement is not true.
In fact, cats can purr to express happiness or comfort. However, this is not the only situation in which this happens for felines.
Cats may also purr as a way of seeking reassurance. It would be like a meditation of their own that they use in stressful moments to try to stay calm. In the same way as human beings try to control their breathing in a bad situation just to manage not to despair.
