I think what makes me so deeply Normal about wolfgirls is the power of contrasts. Physically, the design elements of the ears and tail make them softer at a baseline, but they're not dogs or cats, they're wolves. They're inherently 'undomesticated' and wild and powerful, they don't need your protection or care. But they're not loners-- wolves still hunt in packs. They might have no obligation towards you, but if you're a friend, that's their every drop of blood and sweat they will put into protecting you. If you are worth caring about, that's an unshakeable, deeper-than-words, ride-or-die loyalty. Fang, fist, or steel, 'you are my ally and that means I won't let you be hurt'.
I think that's the root of it; even when the wolfgirl is aloof and seems distant, they are their emotions. Anger means they're angry, any hint of a smile means they're happy, tears mean they're sad, no social deduction necessary. Probably because the wolf bits make it hard to pretend otherwise, admittedly. Tails are for wagging and we love them for this. But either way, the end result to me is the image of someone who takes blunt-force emotional honesty and makes it their strength, and I think that's fascinating, and kind of beautiful. You will know if you mean something to them.
Meanwhile, if a foxgirl were to decide to use my face as a chair, I would thank her for the opportunity to be of use, you know, like a reasonable person
