Keepers at a zoo in Gujarat are putting their big cats into solitary confinement after a tiger in the United States caught the novel coronavirus.
"We have decided to isolate them to avoid any kind of infection," said superintendent Bharatsinh Vihol of the Kamala Nehru Zoological Garden in Gujarat.
"Also, since we have run a planned breeding programme here, it has been decided to restrict mating between the pairs," he told AFP.
Doctors are regularly inspecting the lions, tigers and leopards at the facility, looking for breathing issues, runny noses and coughing.

"We have been sanitising the outer walls of the zoo on a daily basis, while individual enclosures are being sanitised every alternate day," Mr Vihol added.
The zoo usually attracts two million visitors a year but is closed under nationwide lockdown, which allows residents to leave their homes only for essential services.
A tiger at New York's Bronx Zoo tested positive for COVID-19 a week ago.
It is believed it contracted the virus from a caretaker who was asymptomatic at the time.
