CaptionA serval cat hesitates momentarily on the banks of the Salamat river. Servals are common though elusive predators living mainly in the African savannah. They feed chiefly on rodents. A long neck and legs, together with acute hearing, help the cat hunt in tall grass. Servals can even detect the sound of rodents burrowing underground, and will sometimes stand for up to fifteen minutes listening with their eyes shut while hunting.
