Deep in the wilderness of northern Kenya, two boys found a pair of crying cheetah cubs  . The cubs' mother had been killed by a lion. The cheetahs were only a few weeks old. In the wild, about 9 out of 10 cheetah cubs die before they are three months old. They are food for lions. But these cubs were so lucky that they were saved by their "heroes", who brought them to Jane and Ian Craig. The Craigs help save endangered animals at the Lewa Wildlife Conservancy. The Craigs nursed the cheetah cubs back to health -- feeding them with bottles, sleeping with them, and comforting them. They named the cubs Sambu and Toki. But what would become of these cubs? How would they survive on their own? In the wild, cubs stay with their mothers until they are almost 2 years old. During that time, cheetah mothers teach their young how to hunt and how to protect themselves. The Craigs wouldn't be able to find a cheetah mother to teach the cubs. So they turned to a man named Simon King. King has spent more than twenty years studying cheetahs. He gave them a nod of approval when hearing about this, though taking care of two baby cubs would take a huge amount of time. For two years, he would need to have them at his side most of the time. But he felt there was no other choice. And so, when the brothers were one month old, King became their father. The brothers followed King everywhere. If they saw large dangerous and fierce mammals, King would growl at the cubs the way a mother cheetah would have, which was a signal for the cubs to stay away. They learned quickly. King taught the cheetahs to hunt using a toy rabbit as King pulled it around on a rope. With more lessons and training, the brothers began to hunt on their own. King is one proud father now. What worried the Craigs?
There was no cheetah mother to teach the cubs. The cubs were dangerous. They had no time to take care of the cubs. There was no living place for the cubs.
