Danish Zoo Asks for Unwanted Pets to Feed Its Predators

Danish zoo asks for unwanted pets in a new appeal to the public, offering to use healthy animals like rabbits, chickens, and guinea pigs to feed its carnivores. Aalborg Zoo says this approach supports the natural diets of predators such as tigers, lions, and the Eurasian lynx by mimicking how they would feed in the wild.
What Unwanted Pets Can Be Donated to the Zoo?
The zoo accepts small animals such as rabbits, guinea pigs, and chickens. These animals are humanely euthanised by trained staff. The zoo also accepts live horses, as long as they meet specific health rules.
To donate a horse, the animal must:
- Have a valid horse passport
- Be free from illness or treatment in the past 30 days
Horse donors may also be eligible for a tax deduction, as the zoo treats these donations under livestock laws.
How Feeding Unwanted Animals Mimics the Wild
The zoo says feeding whole animals—fur, bones, and all—is closer to what carnivores would eat in nature. This approach helps meet both their nutritional and behavioral needs.

“Small livestock are a key part of the diet of our predators,” the zoo explained. “This is especially true for animals like the Eurasian lynx.”
Feeding animals this way also provides mental stimulation, similar to what they would get while hunting in the wild.
How to Donate Unwanted Pets to the Danish Zoo
Small animals can be dropped off during weekdays. People may donate up to four animals at a time without an appointment. Larger animals, like horses, require prior approval.
All donated animals must be healthy and untreated for illness within 30 days. The zoo ensures that euthanisation is done in line with high welfare standards.
Cultural Acceptance in Denmark
While the idea may seem shocking elsewhere, this practice is common in Denmark. Many locals support it. They see it as a sustainable way to handle unwanted pets while helping zoo animals.
Deputy director Pia Nielsen said this practice has been in place for years.
“When we feed our carnivores, we aim for whole prey—fur, bones, and all. It’s healthier and more natural for them,” she explained. Danish zoo asks for unwanted pets like rabbits and chickens to feed predators, offering a natural diet and an option for ethical animal donation.
Ethical Discussion: A Divisive Topic
The policy has sparked debate. Some praise it as practical and humane, while others find it troubling. The zoo argues that this method respects both animal welfare and environmental responsibility.

Supporters say it’s better than wastefully euthanising pets. Critics worry about the emotional impact of turning pets into food—even ethically.
A Natural and Thoughtful Solution
The idea that unwanted pets feed predators may be controversial, but Aalborg Zoo believes it’s the right choice. It benefits both the zoo’s animals and pet owners who can no longer care for their pets.
As ethical animal care evolves, this method could become more accepted—or at least more openly discussed—around the world.
