A zoo in Denmark is asking for donations of unwanted small pets or horses to feed its captive predators. The zoo stated that it is important to imitate the natural food chain of the animals for their well-being and professional integrity. Aalborg Zoo accepts rabbits, guinea pigs, and chickens as donations for its predators, which require "whole prey" for their diet. Horses can also be donated for feeding the animals, with specific requirements for their condition and size. Donors can receive a tax deduction for the value of the horse, and there may be a waiting list for donations at the zoo.
