Your Cat's Purr Might Be Doing Something Doctors Wish They Could Bottle

That gentle rumble may be more than contentment. It could be repair mode.

The sound of a purring cat on your lap is pure comfort. But that soothing vibration may be doing something for the cat too, something researchers find genuinely intriguing when they look closer.

A cat's purr typically falls within a low frequency range, and vibrations in that ballpark have been studied for their possible links to tissue and bone health. Some scientists suspect purring could aid the cat's own recovery.

It also helps explain a puzzle. Cats purr when happy, but also when injured, frightened, or unwell. If purring soothes and possibly supports healing, it makes sense they would reach for it in the roughest moments.

There is a bonus for you. Being around that steady low hum can feel calming and lower stress for humans too. Your cat may be self-soothing, and quietly handing you some of that calm as a package deal.
