"Big Cat Week" returns to Nat Geo WILD beginning Sunday, December 9, at 8 p.m. This year, see the first ever capture and release of an endangered snow leopard in Afghanistan, watch a cheetah come of age, and hear the life story of a tiger 15 years in the making.

Nat Geo WILD presents a week dedicated to nature’s fiercest felines — big cats — creatures of magnificent strength, ferocity and beauty that are rapidly facing extinction. With visually stunning and powerful stories from around the world, get closer than ever before to lions, tigers, cheetahs, panthers and more as you share in their triumphs, defeats, and epic struggles to survive.
