Purring is a way that cats express emotions. While cats often purr when they’re happy, they can also purr when they’re distressed. Curiously, the low frequency of a cat’s purr can ease breathing, heal injuries and build muscle, while acting as a form of pain relief.
Purring also helps cat owners as well. Cat owners are at 40 per cent lower risk of a heart attack after interacting with cats and hearing their soft purrs. So the next time your cat purrs, you can assume it’s giving you health benefits that your insurance company probably won’t provide.
