Famous animals whose deaths caused outpourings of human grief

Berlin Zoo's prize attraction, Knut the polar bear, was found dead of suspected heart failure aged four. In the wild he would have been expected to live to around 15 years but Knut's short life was a difficult one. Soon after his death The Independent's Steve Connor wrote: "Rejected by his mother at birth and raised by his keeper, Knut's life incorporated a multi-million-euro industry in Knut paraphernalia, a court battle over his ownership, calls for his death, and then for his castration, and an ongoing debate about the ethics of keeping big wild animals in confinement."
