OK - this seems scary - a tiger at the Bronx Zoo tested positive for coronavirus (the article I linked to doesn't specifically say Covid-19 and I know that animals can get other varieties of coronavirus). Either Covid-19 is able to adapt quickly (not good) or it can spin off an animal version of the virus?? Or I suppose the 3rd option is that it's just a "regular" animal variety and everyone is just assuming it's Covid-19 transmitted from the keeper.
On edit - other stories about this say the tiger was tested for Covid-19
