When Pernille Sohl was faced with the upsetting and difficult decision of what to do with her daughter's ailing pony, she could've taken it to the vet.

But instead, the Danish mother decided to take it to the local zoo to be fed to the lions.

The 44-year-old took the pony along to Aalborg Zoo, in northern Denmark, one of the country's biggest tourist attractions to dispose of the family pet.

And she's not the only one.

Since the zoo launched its appeal to pet owners, encouraging them to donate their animals as food for its predators, it's seen 22 horses, 137 rabbits, 53 chickens and 18 guinea pigs donated.
