Supermodel Kate Moss has been slammed by animal rights groups after fronting a campaign for British fashion house Burberry containing animal fur. Among the protestors, the World Society for the Protection of Animals has written to the catwalk beauty enclosing video footage of fur farming. The organisation's director says, "I've written in the hope that she will think twice before wearing or advertising fur in the future." However, a spokesperson for Burberry insists the Moss campaign was as humane as possible and adds, "There will be occasions where the use of fur will be... important to the design and aesthetics of a product. "We will not use fur if there is a serious concern that the fur has been produced by the unacceptable treatment of the animals concerned."
