I'd never heard of it either, thanks for the post.

The fossa is a carnivore and excellent hunter. It preys on small- to medium-sized animals from fish to birds, mice, and wild pigs. But its main food item is the lemur, and the fossa is Madagascar's only predator able to kill the largest lemur species. The fossa is an ambush hunter: it uses its forelimbs and claws to catch its prey, killing it quickly with a bite from its sharp teeth. Fossas at the San Diego Zoo are fed dried cat food, carnivore diet, mice, and large knuckle bones.
