In discussing the Albino lion you have to discuss white lions and the genetics behind white cats generally. This is because there are possibly four types of white lion or at least two, in any event, and when people search for “albino lion” they may be searching, in fact, for “white lion”, which is strictly speaking a different thing.
There are white lions in the world, but no true albino lions. It’s a bit of a misnomer because white lions still have color in their eyes, paw pads, and lips, though the rest of their skin and coat is white. It’s a very rare genetic trait, and the last wild white lion was seen in 1994. The rest are in captivity. The mortality rate of white lions is high because they’re easier targets for other predators than the standard lion, especially as cubs.
