little marmot type thing Originally uploaded by Road Trip

there´s a huge park in downtown Rio and there were tons of cats and these things all over the place. A kid was chasing one and when they get scared they flare out the hair on their rearends and kind of buck (I´m guessing there´s probably a spray of some sort incvolved as well) but the hair/fur under the top coat is bright yellow. Weird things, pretty tame as well, when not being terrorized.
