In a social media post, Aalborg zoo stated the program aims to replicate a natural food chain for its animals. A zoo spokesperson explained that chickens, rabbits, and guinea pigs are important food sources for predators. Using these animals reduces waste while ensuring natural behavior, nutrition, and health for the carnivores.

According to the Aalborg zoo website, donated animals are "euthanized humanely" by trained staff before being used as food. The zoo currently houses several predator species, including Asiatic lions, Eurasian lynxes, and Sumatran tigers.

The zoo’s request quickly sparked controversy. Some social media users expressed outrage, calling the practice disrespectful and insensitive to pets. Critics deemed feeding pets to other animals unacceptable and urged the zoo to stop.

Conversely, some, including past donors, praised the zoo’s professional and humane animal handling. They believe providing pets nearing the end of their lives to the zoo is a reasonable and waste-reducing solution.

From a professional standpoint, some biologists stated that if focused on animal welfare rather than cost savings, using pets as food can meet high ethical standards.

To control the spreading debate, the zoo disabled comments on its social media post, directing inquiries to email.

Deputy director of Aalborg zoo, Pia Nielsen, stated this initiative has been in place for years and is common practice in Denmark. The zoo has long used small livestock to feed its carnivores.

“Providing meat with fur and bones ensures a near-natural diet," Nielsen said, adding that accepting animals like chickens, rabbits, guinea pigs, or horses is not unusual. This practice is widespread in Denmark and supported by both visitors and partners.

According to the zoo representative, predators play a central role in the ecosystem and are essential for maintaining natural balance.

This is not the first time Danish zoos have faced controversy regarding animal treatment.

In 2014, Copenhagen zoo was criticized for euthanizing a healthy giraffe named Marius to prevent inbreeding. The animal's remains were used for research and to feed carnivores like lions, tigers, and leopards.

Just weeks later, the zoo culled 4 lions to make way for a new male, aiming to breed a healthier generation.
