People aren’t the only ones who can become sick with Covid-19. To date, scientists have found the coronavirus in 29 species of animals.
The disease is known to spread among populations of deer and minks. Humans can also pass it to animals, including their pets. Recently, a house cat examined at the University of Pennsylvania tested positive for Covid—likely infected by someone at home.
That has led Zoetis, a company that makes medicine for animals, to create a Covid-19 vaccine exclusively for furry patients. The U.S. Department of Agriculture authorized the treatment for experimental use last year.
Since then, Zoetis has donated thousands of doses to zoos and animal sanctuaries throughout the United States to vaccinate wild animals living in captivity. Experts believe that certain creatures, including lions, tigers, and gorillas, have been picking up Covid-19 from the people who care for them.
“Animals can get sick with the same diseases as people,” says Mahesh Kumar, a microbiologist who led the development of the vaccine. “It’s our job to protect them.” The vaccine is similar to those given to humans—and is administered in two doses three weeks apart.
As for dogs, cats, or hamsters at home, experts say that they don’t come down with Covid that often. But it can happen. So if you do get sick, give your furry friend some space—and don’t cuddle with your fuzzball until you feel better.
