Cheetahs are the fastest animals on land.

Just one of a remarkable family.

One family… 40 different faces.

From the fastest… to the strongest…

The smallest… to the biggest…

These are the cats.

Africa… Home to the king of the beasts.

……

Lions may be legendary, but among cats, they're strange.

That's because they're the only ones to live together, the only truly social cat.
