Cats are mysterious creatures, and one of their biggest mysteries has always been their purr. Purring is a very low sound, around 20 to 30 hertz, and sounds that low typically require much larger vocal chords, elephant sized vocal chords, in fact. So how do cats do it? Well, there's a recent study that may have found the answer. It seems that the vocal chords of cats contain "unusual masses of fibrous tissue" which apparently increase the density of their vocal chords, and that can make the chords vibrate more slowly.
