Madison, Wisc., filmmaker Andy Beversdorf has received death threats over his latest doc, “Here Kitty, Kitty,” airing Saturday on Wisconsin Public Television. The subject: Whether the state should allow killing of feral cats. “It was a big fight between the bird people and the cat people that produced a lot of characters who were very passionate about the whole thing, so it made for good cinema,” Beversdorf told the Wisconsin State Journal. The “bird people” include a professor whose study blames cats for the deaths of millions of birds. More in the Chicago Tribune via The Associated Press.
