Sure, Drew Barrymore, cat owner, once allegedly said, "If I die before my cat, I want a little of my ashes put in his food so I can live inside him." On the other hand, Leona Helmsley attempted to leave $12 million to her dog when she died, so we're not going to settle this with anecdotes alone.
Or with pictures of people's crazy pet clothes.
Fortunately studies have been done measuring self-identified "dog people" and "cat people" on a spectrum of five suspiciously-worded personality traits.
Dog people rated slightly higher in the categories of "extroverted," "agreeable" and "conscientious," all very positive sounding traits, while cat people were rated as slightly more "open" and "neurotic." When you realize "open" is basically a code word for "weird," you might start to suspect that this study was conducted by a dog owner. Who was mauled by a cat.
