It is the fastest of all land animals, its light frame, long limbs and sleek, streamline body, was built for speed rather than endurance, they can reach speeds of 110 km/h. Unlike other cats, the Cheetahs claws do not retract, which act like running spikes. They have large lungs and eyes in proportion to their body to help with spotting prey and predators. They size of the lungs are important to help get as much oxygen into the body as possible. In the wild a Cheetah will normally hunt every day and only consume enough to keep them going for between 24/48 hours. Their metabolism is totally different to that of the other big cats.
