ICYMI: Baby white lion debuts at Belgrade Zoo
In case you missed it: Zookeepers caring for the rare white lion cub born in Belgrade, Serbia on Sept. 27 introduced her to the press this week.
The white lion is one of the most endangered animals in Africa- an estimated 500 white lions are left in the world, almost all living in captivity. White lions are not albino lions- instead, their pigment comes from a genetic mutation.
