Before I say anything, let me be clear: I am an equal opportunity dog and cat lover. I have been completely in love with multiple dogs and cats in my life. That said, I believe dogs are the comic relief in the dramatic movie of our lives. Cats, on the other hand, are like the evil geniuses found in the 1960's spy movies: super-intelligent and always looking for a way to win. Don't believe me? Take a look at a couple of books that came out last year: How to Tell if Your Cat is Plotting to Kill You [2]by Matthew Inman and I Could Pee on This [3]by Francesco Marciuliano.
