But it’s a leap to worry if your household feline can get or transmit the coronavirus, says Karen Terio, chief of the Zoological Pathology Program at the University of Illinois’ College of Veterinary Medicine, which assisted in diagnosing the tiger. “A tiger is not a domestic cat, they are a completely different species of cats,” she says.
