After learning Animal Planet is developing a series about Mike Tyson racing pigeons -- and hearing PETA's trepidation -- we went to the experts: Folk who call themselves pigeon "fanciers" and know the ins and outs of the sport. We asked two pigeon veterans for their gut reactions about the forthcoming TV show, tentatively titled 'Taking on Tyson,' and whether they've ever seen a character quite like Iron Mike on the pigeon racing circuit. PETA is pushing for prosecutors to investigate the show, claiming the program is both cruel to its feathered participants and could involve illegal gambling.
