Any baby animal that has not grown up to an adult yet is more vulnerable to attacks than grown animals. This is especially true of those in the wild. There are so many predators out there that many of the cubs could be attacked. A very small percentage of the cheetah cubs will actually make it to adulthood due to several factors. First, cheetah cubs need their parents to survive.
If a poacher kills their parents, then the cheetah cubs will most likely not be able to survive. Also, cheetah cubs may starve to death because they can’t find enough food. Also, the cheetahs must have a place to live. Their habitat may be destroyed. Last, cheetahs are hunted for their fur.
