Answer 1

In just a few months, the ongoing COVID-19 pandemic has put billions of humans at risk. But as researchers work around the clock to understand SARS-CoV-2, the virus behind the disease, some have begun to worry that countless others may be at stake: animals who could catch the germ from their distant Homo sapiens cousins.

Recent reports of SARS-CoV-2 infecting creatures such as monkeys, dogs, ferrets, domestic cats and even a tiger have raised the possibility that the pathogen could plague other species—including, perhaps, ones already imperiled by other, non-infectious threats.
