A cat's purr is a complex vocalization that may be a powerful, built-in healing mechanism. The specific frequencies of a purr, between 25 and 150 Hz, are known to promote tissue regeneration, build muscle, and even mend bones. This suggests purring isn't just for showing contentment. It could be an evolutionary tool for self-repair, helping cats recover from injury and maintain their bodies while resting. This natural, low-frequency therapy might even benefit the humans lucky enough to be nearby.
