Six lions and three tigers at the Smithsonian’s National Zoo who tested positive for COVID-19 are now on their way to a full recovery. Initially diagnosed in early September, the big cats were eating poorly and showing signs of fatigue. But as of today, they are all on the mend.
According to veterinarians, great cats and apes are the species most likely to contract the coronavirus from humans. That is why zoos across North America are administering a vaccine created by Pfizer subsidiary Zoetis and approved by the U.S. Department of Agriculture.
