Caracal

Cat

it has traditionally had the alternative names Persian lynx, Egyptian lynx and African lynx, it is no longer considered to be an actual lynx. Instead, it is now believed to be closely related to the African golden cat and the serval. The caracal is classified as a small cat, yet is amongst the heaviest of all small cats, as well as the quickest, being nearly as fast as the serval.
