Three snow leopards have died at the Lincoln Children's Zoo in Nebraska of complications from Covid-19, according to AP.
The zoo made the announcement in a Facebook post, describing the deaths of the three leopards named Ranney, Everest, and Makalu as "truly heartbreaking”.
The zoo began treating the leopards and two Sumatran tigers for the virus last month. The zoo said the tigers, Axl and Kumar, have made a recovery.
The zoo said it remains open to the public and continues to take precautions to prevent the spread of Covid-19 to humans and animals.
