Interesting question that I've mostly ignored really, lmao.
Well, I have used "people" in the text before, I feel like that one is one that is somewhat commonly avoided already among furry writers?

But as for their equivalent of "human" specifically? I'm not sure. I think human could still work given the origin of the term, but I also think the species differences among all the amthropomorphic species would mean that they perhaps focus on a different aspect of what makes them different to regular animals.
Maybe they'd go with "sapiens" and highlight the difference in mental capabilities over their animal counterparts?
