The general consensus on the inclusion of cat ears as a customization option for Destiny's player avatars is: no. It would be too strange, even to be included in a Bungie game. Also, cat ears would subtract from the somber tone of Destiny. It would damage the theme of desperation and it would serve to be a distraction in the game world. In conclusion, the Bungie community, at least 75%, dislikes the idea of cat ears as a customization option and within that percentage many are harshly opposed to it.
