The pampas cat, Felis colocolo, is named for its main habitat, the treeless plains of South America, but it also will live in forests and is often found right at the border between these two habitats. It is slightly bigger than a domestic cat, more sturdily built, with a longer head and tail, a slightly flattened face and more pointed ears. Nearly all pampas cats have bars of colored fur on their legs, but the color of the rest of their coats varies wildly, and they have a mane of longer hair on their backs which is raised to signal fear or aggression even more obviously than the domestic cat's back-arching. Not much is really known about their behavior in the wild; it is assumed that they are nocturnal and eat rodents and ground-nesting birds and sometimes they raid henhouses.
