I don't like some "furry" stuff, but it doesn't mean I'm automatically put off if a series is about anthopomorphic animals. There are a bunch of things with animal characters that I like, like Mouse Guard, Duck Tales, My Little Pony, Ruby Quest etc.
I think so long as the creatures are either like... quite realistic fluffy animals like Mouse Guard, or they're cartoony looking like Duck Tales, I'm perfectly happy, so the first example in the thread I'm like "aww! That's cute! I'd read that!" So anything like Sonic the Hedgehog or Pokemon I'm happy with... and the point where it triggers my "NOPE" reaction is when the anthro characters are....drawn to be sexy.
So as soon as they like... have proportions a bit too close to a sexualised depiction of an adult human with defined muscles and prominent breasts, and it's combined with a cartoon animal face with big shiny eyes, that's the kind of stuff where a non-furry like me goes "uhhhh... okay, this is for furries, not for me, seeya!".
Like no shade intended on furries for liking that and enjoying it, but that art style, where the face is very much "cartoon animal with big cute anime eyes" but the body is "sexy human but with fur and a tail and paws" is what will immediately put a non-furry off. Like as soon as it looks a bit too much like the artist would like to have sex with the purple cartoon wolf, not accompany them on cute adventures, I'm immediately uncomfortable. About the furthest I can go is Disney's Robin Hood or Zootopia, largely because the characters are still relatively animal-like and not too muscular or with really pronounced sexual characteristics.
Of course, some non-furries will put the bar even higher and won't touch ANYTHING even a little anthro, but I think most are like me and it's all about not liking that specific furry aesthetic of very anime-animal-like face, hands and feet combined with unsettlingly human-like torso, arms and thighs. So if you don't want to get pigeonholed as a "furry artist" that's the area to avoid and either go more cartoon-like or go "they're humans but with horns and some patches of scales". Really though, there's nothing wrong with being a furry/scaly artist, furries seem like mostly decent people and they're an audience that lavishes stuff with attention and support, so it's really just whether you want to be in that niche or not.
