So, on your next trip to Cape Town be sure to visit the Cheetahs at Spier. If you bring a little extra money along you'll have an opportunity to visit the cheetahs inside their enclosure, and even stroke them - if you're brave enough!
Being able to reach a speed of 120km/h makes the Cheetah the fastest land animal around. They are reportedly able to accelerate from 0 to 110km/h in only 3 seconds... which is more than twice as fast as my 6-cylinder BMW!
