Cat counts. When I was a little kid and we had cats, I never really thought of them in terms of having a sex (only in terms of the fat one, the skinny one, and the one that always tried to scratch my eyeballs out). They all looked the same to me. Now that I've got one of my own, however, neutered though he may be, there's never any doubt in my mind that he's a dude.

Video games and beer are fine for a male roommate -- I mean, he's gotta have some kind of outlet -- but if you ever catch him so much as pausing on a football game on the teevee while channelsurfing, start slipping estrogen tablets into his beer. Sports: the last vestige of the caveman gene. Nothin' doin'.
