Kitties can has claws? In DnD beast races sometimes get a "natural weapon" that they are considered to be wielding when otherwise unarmed. It can give bonus damage / attack, or even an effect. I think bonus melee damage for beast races would be pretty boss.
EDIT: Would be cool to have racial perks at each x levels that strengthen what the player's race is considered to be good at. Khajit could get a bleed on hit effect or bonus damage for claws as they level, for example.
