A zoo in Indonesia may slaughter some of its animals to feed others, such as a Sumatran tiger and a Javan leopard, if it runs out of food in coming months after the coronavirus pandemic forced it to shut it doors.

While its 850 animals are being fed smaller portions than usual, the zoo is contemplating a “worst-case scenario” of culling some animals to feed others as it expects to run out of food in July, Reuters says.

The Badung zoo in Indonesia’s fourth-biggest city, which usually earns about 1.2 billion rupiah ($81,744) a month from visitors, shut on March 23 as part of a wider country lockdown to try to contain the outbreak.

“We have around thirty dotted deer, and we have identified the old and unproductive ones (who can no longer breed) to be slaughtered to save the carnivores, such as the Sumatran tiger and Javan leopard,” said zoo spokesman Sulhan Syafi’i.

Some birds including geese may also be culled, he said.

Big cats, including a critically endangered Sumatran tiger named Fitri, now get 8 kg (18 lb) of meat every two days, down from 10 kg previously.
