Oh my god I can't even explain Cat's thoughts. Just...just watch these (http://tasteslikehair.livejournal.com/1231.html#cutid1) and mind delve at your own risk.

FOR THE RECORD, it never really comes up in canon but Cat is occasionally shown to be a little more clever than she acts, but I'd say it's about 95% legit, 5% she really likes attention.
