A cat’s purr has always been a sign of contentment and happiness.In fact, the Real Academia Española itself defines the purr of a cat as the action and effect of producing a kind of snoring that shows well-being.
For cats it is innate; they emit a sound similar to a continuous vibration which is dull, hollow, and deep, with a frequency of between 25 and 150 vibrations per second.
However, its meaning is not clear.Through various analyses, British researchers have discovered that cats purr to get what they want from their owners, and in nature, to call for help if they are very unwell, or to express that they are not thinking of attacking and do not want conflict in tense situations.
Everybody has listened to the curious purring of a cat: somebody strokes them and they purr.Nonetheless, it is still not known how they make this sound.There are theories, but a unanimous verdict has not been reached.It is said that the purr comes from some folds or false vocal chords.There is also the hypothesis that it happens thanks to the contraction of certain larynx muscles.
