Why and how do cats purr?
Question: Why and how do cats purr?
Answer: Well, first, purring is not limited to cats. It has also been attributed to racoons, civets, weasels, martens, skunks, badgers, and otters. Cats most often purr when happy and content, but can also purr when stressed, in pain, or even during birth. Purring may be learned early, as the first method of communication between the blind and deaf newborn kitten and its mother. Veterinarian Neils C.Pederson, author of “Feline Husbandry”, believes that purring is initiated from within the central nervous system and is a voluntary act. In other words, cats purr only when they want to.
How they purr is still somewhat of a mystery. Some feline experts say the sound is created by the vibration of vocal cords during inhalation and exhalation. Others believe purring is a vibration caused by blood passing through a large vein in a cat's chest.Interestingly, the measurable “Hertz” of a cat's purr lies between 25 and 150; sound frequency in this range can stimulate bone growth and healing.
