I bet I could manage cattier. I wasn't going to bother though. =)

(However if you'd like to interpret that as catty as well, it would be because you're not threatening enough, if you wouldn't like to bother interpretting that as catty, then it would be because so far you seem perfectly amiable and not inclined toward homewrecking or whatever the phrase would be for couples living "in sin" *gasp*)
