I haven't a clue. Certain anthros creep me out real easily, yours don't for whatever reason.
I think it's because your style is very unique. The way you draw them gives them just enough flow to still look cartoony while still being very humanoid, a balance also found in The Lackadaisy Cats, which also doesn't creep me out.
I guess if I had to pick something, it would be pose and expression, which always lends itself to the atmosphere and style. And I guess the fluff as well, because you draw it with very stylized curvatures that look almost abstract in a way. Your drawings of hair were always pretty stylized.
