COLUMBUS, Ohio — The Columbus Zoo and Aquarium announced Wednesday that a tiger died of complications with COVID-19.

The zoo announced on Facebook that a 14-year-old Amur tiger named Jupiter died Sunday, after developing pneumonia caused by COVID-19. According to National Geographic, certain types of animals including big cats are particularly susceptible to catching the coronavirus.

Jupiter was receiving long-term treatment for chronic underlying illnesses, which made him more susceptible to this virus, the zoo said in a release. Jupiter is the first and only animal to succumb to COVID-19 at the facility, according to the Columbus Zoo.

Jupiter started acting ill on June 22, the release said. He was not interested in eating, and was reluctant to stand, move or interact with keepers. When this continued into the next day, Jupiter was anesthetized for examination and treatment.
