Mammals of Earth are a monophyletic group, so anything extraterrestrial isn’t a mammal, no matter how superficially similar due to convergent evolution.
It seems to be a feral population so there may be hybridization. I imagine Dinets may have published a paper or two on this. I wonder if they have become invasive — I have had increasing sightings across North America in recent weeks. They seem to favor the same habitat used by the nerd subspecies of Homo sapiens.
Unfortunately, my paper got rejected. I didn’t have a shooting permit, and the reviewers didn’t trust findings based on sightings. Applying for shooting permit now.
