DEAR READERS: Several mammalian species, including cats, are susceptible to infection by people with COVID-19. Infected cats could also spread the disease to wildlife, notably foxes, squirrels and rabbits. I am also concerned about the global pork industry, since pigs are susceptible to SARS-CoV—2 and thus potentially at risk from infected workers. CAT WITH RESPIRATORY DISEASE HAD SARS-COV-2A 16-year-old cat with severe respiratory illness was humanely euthanized and diagnosed with a SARS-CoV-2 infection, according to Pennsylvania State Veterinarian Kevin Brightbill. The cat lived in a home with several people who had positive COVID-19 tests.
