Before revision:  This indicates that SARSCoV2 is a highly adapted human pathogen. Of the species studied, the next highest binding affinity after human was pangolin , which is most likely explained by a process of convergent evolution. Binding of SARSCoV2 for dog and cat ACE2 was similar to affinity for bat ACE2, all being lower than for humanACE2, and is consistent with only occasional observations of infections of these domestic animals.
After revision:  Binding to pangolin ACE2 was similar to affinity for bat ACE2, all being lower than for humanACE2, and is consistent with only occasional observations of infections of these domestic animals.
