A zoo in northern Denmark is asking pet owners to donate their unwanted guinea pigs, rabbits, chickens and even small horses – not to put them on display but to feed them to the zoo’s predators.

The zoo explained in a Facebook post that “if you have a healthy animal that needs to be given away for various reasons, feel free to donate it to us.”

The organisation suggested chickens, rabbits and guinea pigs make up an 'important' part of the diet of its predators, which include tigers, lions and lemurs.
