The Bay Cat is the mystery member of the cat family. Next to nothing is known about them. The Bay Cat is found only on the island of Borneo. Borneo is the third largest island in the world. The island is divided among three countries: Brunei and Malaysia in the north, and Indonesia to the south.

Borneo Cats are about the size of a long-bodied housecat and are generally grayish or reddish. The Bay Cat lives along the edge of deep dense tropical jungles by riverbanks or rocky outcroppings. Their survival is wholly dependent on the presence of healthy rainforest. These cats are incredibly rare and almost never photographed. http://www.wildcatconservation.org/wild-cats/asia/borneo-bay-cat/
