Cheetah's are the fastest land mammal in the world -in the 1900's there were an estimated 100,000 cheetah's worldwide and now there are only 10-15,000 with 1/10 of them living in captivity. Three to five cubs are born per litter but when only one is born many times the mother will abandon them and they are raised in captivity. Cheetah cubs are often preyed upon by lions, leopards, and hyenas. They are killed for their furs- and because of loss of habitat and conflict with humans the cheetah population has been declined. They could become extinct in the next fifteen years.
