We associate purring with content cats, but felines also purr to soothe pain or communicate needs. Discover the science of the purr.
Vocal Fold Vibration Mechanics

The Therapeutic Effects of Frequencies
Purr frequencies (20-140Hz) correspond to tissue healing and bone density growth, suggesting purring is an evolutionary healing mechanism.
