Animal Fight Night

In an all-American big-cat showdown, a bobcat and a lynx fight tooth and claw for territory. Spanish fighting bulls show exactly what it means to have fighting in your genes as they go head-to-head to be leaders of their herd. And in the Sonoran Desert, a meat-eating mouse takes on one of the biggest centipedes on earth in a fight to the death. Fur flies and tempers flare in the animal kingdom.
