I partially feel as though most people are saying "lioness" because of the preset biased they might have. Since they've only ever seen "Kitchiki" as a lioness, they only want to see Kitchiki as a lioness, but I'm not going to fight anyone on the matter! :') Kitchiki can be whatever you want it to be... Personally? I thought it sounded like the name of a Lynx character. That's just my view on it though.
Back when I first started to watch you, I always seen Kitchiki to have more lioness aspects. So I viewed her as a lion. But over time and the more I seen of her with your artwork, I seen more then just a lion. I'm glad you put the snow leopard option, because that is what I checked. Yes I still see the lion features, but I've been seeing more of the snow leopard attributes as far as the bigger ears and tail. So I would say she is mostly related to the snow leopard.
