when a manga has "beastfolk" that look humanoid but with cute bear/cat ears, I check if literally all of them are conveniently drawn with shaggy obscuring hair. You are trying to avoid either 1) extra human earlobes or 2) eerie blank neck where they ought to be - I have no respect for an illustrator who cowardly avoids committing either way. Reveal them
There's a series out there that makes a plot point of this; it's called,
I believe, Maou to Ore no Hangyakuki (The Dark Queen and I Strike Back), but I can't remember 100% and can't be assed to go reread it to confirm, considering it's one I dropped out of boredom.
Anyway, the setting has both fully anthropomorphic beastmen and humanoid with beast ears beastkin; the latter typically only has 1 set of ears, the animal ones, but there are occasionally people born with both animal and human ears. They're also hated by everyone, called things like "4 ears", and it's common for humans to cut off the beastkin's human ears.
