Why do cats purr?

Although only lions, tigers, leopards, and jaguars can roar, all cats can purr. Researchers aren’t quite sure why cats produce this pleasant rumbling sound, but they think it starts as a way for mommas to reassure kittens that they’re safe. Once cats grow up, purring evolves to convey general contentment. Some scientists think that a cat’s purring sound might even help it develop stronger bones!

But not all cats can purr. Domestic cats, some wild cats and their relatives — civets, genets and mongooses — purr, and even hyenas, raccoons and guinea pigs can purr. However, cats that purr can’t roar, and cats that roar can’t purr because the structures surrounding roaring cats’ larynxes aren’t stiff enough to allow purring.
