What is a fassie?

A fassie, or fossa (Cryptoprocta ferox), is a carnivorous mammal native to Madagascar, resembling a small puma or large mongoose. It is the largest predator on the island and primarily preys on lemurs, birds, and small mammals. The fossa is known for its agility, allowing it to climb trees with ease, and it plays a crucial role in Madagascar's unique ecosystem. Despite its cat-like appearance, it is more closely related to civets and mongooses.
