The Secret Lives of Big Cats

The snow leopard becomes legendary for its rarity and elusiveness.

Pumas are distantly related to lions and much more closely related to cheetahs.

Unlike other cats, lions are highly social, forming prides of up to 35 animals.

Like most big cats, leopards are masters of secrecy because they need virtual invisibility to hunt.

Seeing an elusive wild jaguar is now a possibility rather than a dream.

Cheetahs are possibly the fastest land animals that have ever lived and they are daytime hunters.
