Diagonal Dialectic

The guy was sitting with a companion, at a table kitty-corner from ours. Is it “kitty corner” or “catty corner”? Never mind, I digress.

Now that I think about it, and having reread my adorable and witty yet ultimately pointless description of the aforementioned guy’s strange behavior, I think I’ll shelve that and we can discuss the digression instead.

So, which is it? Do you say “kitty corner” or “catty corner”? Take a stand and hold your ground. Don’t cop out and say that you say “diagonal”. No one does that, not in real life.
