Donated pets will be “gently euthanized” by trained staff and then used as “fodder” to take care of the well-being of predators, Aalborg Zoo said.

A zoo in Denmark has appealed to the public to donate their healthy unwanted pets as part of a unique effort to provide food for its predators. Aalborg Zoo has asked for donations of live chickens, rabbits, and guinea pigs, which it says are "gently euthanised" by trained staff.

Aalborg Zoo has started asking for donations of small pets to feed its big cats, offering to ‘gently euthanise’ animals like guinea pigs and rabbits before they become dinner for Sumatran tigers and Asiatic lions. In a lengthy Facebook post that caused a fierce debate, the zoo explained it’s their responsibility to copy the natural food chain.
