The frequency of a cat's purr, around 25-150 Hz, is thought to have therapeutic effects on both humans and cats themselves.
Research suggests purring may have healing properties, aiding in bone density and promoting tissue regeneration. It's a form of self-healing.
Scientists believe that purring releases endorphins, the body's natural painkillers, explaining why cats often purr when injured or distressed.
Cats can also purr when giving birth or nursing their kittens, creating a calming environment for themselves and their offspring.
