Telling you that cheetahs are the fastest land animals will probably not surprise you, but these sprinters demonstrate one or two other interesting features which are not necessarily a matter of common knowledge.
For example, were you aware of cheetahs being the only ones among big cats that can’t roar?
This oversized kitty will purr instead, most loudly when grooming, when in company of other members of its species, or when being petted – should one dare to. Seeing this video might make you want to try, but be sure to do so in a controlled environment. Otherwise you might learn the hard way why cheetahs can’t be outrun.
