The Aalborg Zoo in Denmark said it would take certain surplus pets such as chickens, rabbits and guinea pigs to be "gently euthanized" and fed to its 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.
