Madagascar, an island country in the Indian Ocean with exceptionally diverse habitats and a host of species that evolved here and live nowhere else, has its own small carnivores. The largest, called the fosa (or fossa), is often described as “cat like”—or, some say, a cross between cat, mongoose, and dog—though it is not actually a felid. A member of the Eupleridae family, which covers all of the island’s meat-eaters, it prefers a deep-woods habitat and leans on lemurs for much of its nourishment.
