Oh, trust me, I understand entirely - there's nothing quite like seeing the worst traits of something you already can't stand, especially when they're being rewarded like that.

Usually it's people and not animals who bring that sort of disgust out in me, though - I'll have to tell you about one of my employees sometime, he's absolutely vile. But at least with the people you can just blame them for all their undesirable traits and be done with it.
