Purring is a unique vocalization found in cats. It's not just a sign of contentment but also a form of communication and self-healing.
Scientists believe that cats purr by contracting their laryngeal muscles at a rate of 25-150 vibrations per second, which remains a mystery.
Research shows that the frequency of a cat's purr can promote healing, reduce stress, and even lower blood pressure in humans.
The act of purring releases endorphins, the body's natural painkillers, making it a self-soothing mechanism for cats during times of stress or injury.
While domestic cats are known for purring, wild cats like cheetahs and cougars also purr, suggesting its evolutionary significance in felines.
Understanding the science behind purring sheds light on the intricate ways in which animals communicate and adapt for survival in their environments.
