Can a Purr Help Heal?

Some scientists have suggested that purring could help cats heal.

Low vibrations, in a similar range to a purr, have been studied for their effect on bone and tissue in people and animals.

It is an intriguing idea, but it hasn't been proven in cats. For now, it is best seen as a theory rather than a fact.

One thing we do know is that not every big cat can purr. Cheetahs, pumas and other smaller wild cats purr, while lions and tigers are known for their roar instead.
