Fossa
The fossa (Cryptoprocta ferox) is a unique carnivorous mammal endemic to Madagascar. Unfortunately, the animal is vulnerable due to a number of factors, including habitat loss and—you guessed it—cats. Feral cats compete with the fossa for food; recently, a team of researchers got camera trap photos of cats successfully hunting lemurs and snakes in the jungles of Madagascar. Invasive cats pose a particularly worrisome problem on islands like Madagascar, where native species have evolved in isolation from many predators.
