A cat can purr even as it is dying. It's not just a sign of pleasure: even a frightened, sick, or dying animal can make that low-pitched sound that we find so reassuring. The most common belief is that purring is a sign of feline happiness, a sort of audible smile. But science has discovered that things are much more complicated, and that purring is one of the cat's secret weapons. The theory is this: purring is not only a way of communicating positive emotions, but it is also used for healing and survival – both among cats and with humans. And behind this sound that we take for granted, there is still a great deal we do not understand. One of the key aspects of this story is the relationship between the kitten and its mother: from the very second day of life, the kitten cannot meow, so it purrs with its mouth closed while feeding, signaling its well-being to its mother. She responds by purring in turn, in a silent dialogue that reassures both of them. But there are also those who have spent their lives studying the mystery of this sound: in the 19th century, Owen and Pocock attempted to distinguish the purring of “normal” cats from that of big cats, such as the cheetah, without ever arriving at a definitive answer. Today, we know that the purring of domestic cats has a frequency ranging from 25 to 150 vibrations per second, and that each cat has a sort of sonic fingerprint, which changes according to age, health, mood, and even its relationship with humans. One of the most widely accepted theories is that cats use their vocal cords and rapidly move their laryngeal muscles to produce this continuous vibration, both when inhaling and exhaling. But the real breakthrough came from a 2003 study published in Scientific American: the frequency range of purring promotes bone healing and accelerates recovery from fractures. In essence, cats don't just communicate: they heal themselves while purring. And this ability could explain why, over the course of evolution, the domestic cat does not suffer from many of the bone diseases that affect other pets, such as dogs. What's more, purring appears to be a social strategy: cats also use it when they are stressed or frightened, perhaps to ask for help or to reassure those around them – whether it's another cat or a person. There is one detail that few people know: big cats like tigers and lions can make similar sounds, but only when exhaling, and not with the same continuity as domestic cats. And then there’s the question of words: almost every language describes purring with an onomatopoeic term that echoes that rhythmic sound – in English, purr; in French, ronronner; in German, schnurren; in Spanish, ronroneo. When you see a cat purring, you never really know what it's feeling: it could be happy, but it could also be asking for help. And this ambiguity is perhaps the true feline superpower. We usually think of purring as a straightforward signal – yet it is one of the most multifaceted and mysterious forms of communication in the animal kingdom. No one, not even scientists, has fully understood it yet. A cat's purring is both a request and a remedy.
