It's not my cat.
I'm not sick. Sick would be fucking the cat, having it lick tuna water off your penis, or eating the cat. or all of the above in any order...
I'm willing to bet there are, at least, a couple of psychotherapists out there willing to disagree with you on that. Then there's the whole issue of just because you haven't sinned (you haven't, right Mike?) doesn't mean sin doesn't dwell in your heart. But, since I'm not Catholic or anything, I'll leave that one for you to wrestle with.
