It's time to move our cattitudes out of the dark ages and stop demonizing America's favorite pet. The simple truth is cats make the world a better place. So if you see a black cat on Friday the 13th (or any day) consider yourself lucky. After all, the only bad luck following cats is people's superstitions.
I can't say for sure why I've never been a 13th-o-phobe. Maybe it's because I grew up Catholic and celebrated "Good" Fridays every year -- even when they fell on the 13th. Or maybe it's because I now live in New York City, where the only bad luck you'll typically encounter -- like a Con Ed blackout or a cabbies' strike -- happen whenever they damn well please.
