Fossa. Fossas are the largest carnivores in Madagascar. Secretive and cat-like, these predators are well equipped for chasing down lemurs in the forest. They are famed for having some strange development, courtship and breeding traits. As they grow, female fossas go through a period of 'masculinisation' during which their genitals resemble those of a male. Breeding takes place in the autumn when a female attracts a large number of males.
The Fossa is a mammal and is thought to be most closely related to the mongoose. Most know of this animal because it is the second largest carnivore on the island of Madagascar, second only to the Nile crocodile.hat is known is that when the Fossa pups are born they are both blind and toothless. The pups will be completely dependent on their mother for about one year and do not leave the family nest until they are four to five months old. It is not until the Fossa is four years old that it will begin to breed.
