The frequency of a cat’s purr is between 25 and 140 Hz. This covers the same frequencies that are therapeutic for bone growth and fracture healing, pain relief, swelling reduction, wound healing, muscle growth and repair, tendon repair, and mobility of joints. This would support the theory that purring is not just self-soothing for #cats, but is actually a form of self-healing. #myphoto #december #felines #wellbeing @ladyhug
