The Copenhagen Zoo, which made headlines in the past for killing and dissecting a healthy giraffe, recently put down four healthy lions, including two cubs.
In February, the zoo said it killed Marius the giraffe because he was a "surplus" animal and "his genes were well represented among the captive giraffe population in European zoos," noted The New York Times.
On Monday, the zoo killed the lions to make room for a new lion, reports The Guardian. Ironically, the lions ate the remains of Marius last month.
“Because of the pride of lions’ natural structure and behavior, the zoo has had to euthanize the two old lions and two young lions who were not old enough to fend for themselves,” said the zoo in a statement.
The zoo claimed the 10-month-old lions would have been killed by the new male lion.
“I think people are more enlightened after Marius [the giraffe],” said zoo chief Steffen Stræde. “Marius hasn’t made us the least bit afraid, because what we are doing is the most correct thing to do.”
