A woman says she donated her daughter’s pony to Aalborg Zoo in Denmark to be “gently euthanized” and used as food for captive predators.

"We have a responsibility to imitate the natural food chain of the animals — in terms of both animal welfare and professional integrity," Aalborg Zoo says.

A Denmark zoo is asking the public to donate their pets -- particularly chickens, rabbits and guinea pigs -- so that they can feed them to the zoo’s predators.
