Animal Qualities and Virtues

Do the qualities and virtues of animals stack in their bonuses? For example, does a wolf get +6 on all rolls involving hearing (it has Sharp Ears as a virtue and as a quality; total Awareness of 9 plus die roll) or a falcon +6 on all rolls involving eyesight (Keen Vision as a virtue, Keen Eyesight as a quality; total Awareness of 13 plus die roll)?

I'm pretty sure they're supposed to stack. Most of the Qualities are fairly limited, and most animals won't have lots of Qualities. So it's probably not that problematic.
