Fossa

The Fossa ( pronounced foosa) is the largest carnivore on the island of Madagascar. It has no natural enemies, but is in danger of extinction because the forest is disappearing. The Fossa only lives on Madagascar, a big island located in the Indian Ocean. The Fossa is a meat-eater that eats small animals and birds, as well as insects and frogs. Sometimes it catches lemurs. The Fossa looks like a cat, but is actually a close relative of the mongoose. Scientists think that it was related to cats a long time ago.
