Pelusa, a fourteen-year-old female polar bear, look through the bars of her cage at Mendoza's Zoo, some 1,200 kilometers (750 miles) west of Buenos Aires, Argentina, Tuesday, July 22, 2003. Pelusa, normally white, turned violet after veterinarians administered a drug to treat a skin infection. Veterinarians said she should turn to her normal color within a month.
