To understand the origin of novel recombinant variants, it is crucial to identify hosts susceptible to multiple alphacoronaviruses. The receptor for FCoV-2 and CCoV-2 is aminopeptidase N (APN), with the APN of the domestic cat allowing entry of FCoV-2 and CCoV-2. However, natural infection with CCoV-2 has been reported exclusively in canids.</div></div><div><h3>Methods</h3><div>We investigated an outbreak of CCoV-2 in captive snow leopards (<em>Panthera uncia</em>).
