Why Do Cats Purr ?
Cats have been captivating human hearts for thousands of years with their endearing and enigmatic behavior. One of the most distinctive and adorable features of our feline friends is their ability to purr. This rhythmic sound has been a subject of fascination and intrigue for centuries, and today, modern science is shedding light on the many facets of this mysterious vocalization. In this article, we will explore the science behind cat purring, its potential self-healing properties, and how it serves as a form of physical therapy for our feline companions. We will also delve into the work of notable figures in feline research, such as Hank Green and the popular YouTube channel Scishow.
The Mechanics of Cat Purring
Before we dive into the scientific aspects of cat purring, let’s start with the basics: what is purring, and how do cats produce this sound? Purring is a low-frequency, continuous sound made by cats during both inhalation and exhalation. It is often associated with contentment and relaxation, although cats can purr in various emotional states, including fear and distress.
The mechanics of cat purring are not fully understood, but scientists have made significant progress in recent years. One prominent source of information on this topic is the popular science communication channel Scishow, hosted by Hank Green, which has explored the subject of cat purring in detail. It has long been believed that the sound of purring is produced by the rapid contraction and relaxation of the muscles within a cat’s larynx (voice box). However, more recent research suggests that it may be more complex than that.
A study published in the journal Current Biology in 2019 proposed a new theory that purring involves the synchronous activity of the laryngeal muscles and the diaphragm, the primary muscle responsible for breathing. According to this theory, a neural oscillator in the cat’s brain sends signals to both the laryngeal and diaphragmatic muscles, causing them to contract rhythmically. This simultaneous contraction produces the characteristic purring sound.
The Self-Healing Power of Purring
Now that we have a better understanding of how cats produce the sound of purring, let’s delve into the fascinating science of its potential self-healing properties. Cats are known for their remarkable ability to heal from injuries more swiftly than many other animals. Purring, it turns out, might play a significant role in this.
