COVID-19 can infect both the European mink (Mustela lutreola) and the American mink (Neogale vison). Ferrets are used to study COVID-19.[6] Ferrets get some of the same symptoms as humans,[7] but they get less sick than farmed mink.[8] Ferrets are a fairly uncommon animal to use as a model, but mice were not an easy model of COVID-19 because mice lack the ACE2 gene.[6]
