Here's the thing, cat ears don't fit into Destiny. Let me explain why. If people had actual cat ears in Destiny they would be a [b]different species[/b]. Take [i]Final Fantasy XIV: A Realm Reborn[/i] for example. There are characters with cat ears and a tail, but they aren't Human (or whatever Humans are called in that game). There are (as of yet) only three confirmed character [u]races[/u] in Destiny. Bungie doesn't even call them species because they are most likely different kinds of Humans that were changed by magic or technology. To have cat ears they would have to introduce an entirely new species into Destiny's universe and that could, and probably would, ruin much of the established story and lore (if you need to me clarify this point I will, but it should be pretty obvious). [i]What about fake cat ears?[/i] Those wouldn't make any sense. You wouldn't be able to wear them under your helmet and having them on it would just make you a target. You have to remember that the Guardians aren't cheery adventurers. They are beaten down soldiers who are doing what they have to to keep Humanity alive. They are the people who've banded together to defend and fight for those who can't. Cat ears aren't a priority nor even a desire for these kinds of people. It would be a waste for resources to make fake ones and it wouldn't be practical. As far as I know, we aren't civilians in this game. We're Guardians, Be brave and [i]ad astra[/i].
