In this episode, the focus is on Chiku, a 12-week-old cheetah who lives in the Masai Mara Reserve in Kenya and who has just discovered how to hide using her spots as camouflage. The cheetah is the fastest animal on earth, capable of running up to 95 kmph. More like a racing dog than a cat, it has a slender body, long legs and a small head. Large nostrils and a big rib cage help it to take deep breaths which power its body with oxygen. It also has claws like running spikes to stop it slipping and a long bendy spine. When she was born, Chiku was just 30cm long and weighed under 300 grams. Though she is now growing teeth and eats meat, she still suckles milk from her mother. Soon she will learn to repel uninvited diners, but there is one she is not yet ready to handle - the lion!
