Vrnením

Vrnením is a term used to describe the act of purring, typically associated with cats. This rhythmic, vibrating sound is produced by the cat's larynx and diaphragm muscles. The exact mechanism is still debated among scientists, but it is generally understood to involve rapid oscillations of vocal folds and muscle contractions. Cats purr in a variety of situations, most commonly when they are content, relaxed, and feeling safe. This is often observed during petting, nursing, or resting.

However, purring is not exclusively a sign of happiness. Cats may also purr when they are stressed, in pain, or injured. In these instances, it is thought to be a self-soothing mechanism or even a way to signal their vulnerability to others. The frequency of a cat's purr typically ranges between 25 and 150 Hertz. Research suggests that these specific frequencies may have therapeutic benefits, potentially aiding in bone healing, pain relief, and wound healing. Kittens begin to purr shortly after birth, using the sound to communicate with their mother. The unique vocalizations of each cat's purr can also serve as a form of individual recognition.
