Researchers at Fauna Communications found that the frequency of a cat’s purr covers the same frequencies that are therapeutic for bone growth and fracture healing, pain relief, reduction of swelling, wound healing, muscle growth and repair, tendon repair, and mobility of joints. It seems that with the purr, nature provided cats Continue Reading
