A cat's purr can heal the cat and the people around them.
Cat purrs are soothing to listen to but they also enable the cats to heal injuries to bone, joints, muscles, and other tissue.
Both Domestic and Wildcats produce a strong frequency between 25 Hz and 150 Hz and these low frequencies are associated with healing.
All cats purr at this frequency except for the cheetah and the cheetah’s purr which uses a slightly larger range of frequencies that correspond to all of the best healing frequencies
Cat purrs can also help with infection, swelling, pain and burns, and improve muscle and bone growth and joint mobility.
This ability to repair injury may be one of the reasons we talk about cats having nine lives and their ability to repair from injury.
