Nah, you don't believe all those superstitions about Friday, the 13th, do you? Of course not. You don't avoid walking under ladders or shudder when a black cat crosses your path. Never. That's why we're not afraid to run this picture of a black cat on Friday, the 13th, even if this is one of the Capitol Hill Blue house cats, a little creature with the descriptive name of "AC," which stands for Anti-Christ." Spend a few minutes with this terror on four legs and you'll understand why.
