The cat-fox is a possible new species of
carnivoran discovered on the Indonesian part of the island of Borneo.
It was first discovered by Swiss-based environmental group WWF in 2003, using a night-time camera trap in Kayan Mentarang National Park. The mammal is slightly larger than a cat, with red fur, a long tail, and hind legs that are longer than the front legs. Its overall appearance is something between a cat and a fox. In some ways it resembles the Fossa of Madagascar.
The WWF plans to set traps to capture and study the animal. If this proves to truly be a new species, it will be the first new carnivore discovered on Borneo since the Borneo Ferret Badger (Melogale everetti) in 1895. Other new mammals are discovered in Borneo with some regularity, for example the rodent Pithecheirops otion in 1993 and the bat Myotis gomantongensis in 1998. Some individuals have speculated that the animal in the photographs is a known (but exceedingly rare) species, Hose's Palm Civet
