Purr

There's also a clear link between cat ownership and a lowered risk of strokes or heart problems, as a cat's purr lowers blood pressure.

Cats purr for many more reasons than you would think.

Most people associate a cat's purr with it being happy, but that's not always true.

Some cats have a slightly different purr for when they're hungry, and mother cats also use their purr to communicate with their newly birthed kittens.

Most unexpectedly, cats sometimes purr when they're injured, and it's been suggested their purr actually helps their body to heal faster!
