Are You a "Dog" Person or a "Cat" Person?

Are there differences between "Dog People" and "Cat People"? Eric Barker of Barking Up the Wrong Tree assembles some research that suggests that in fact is the case:

"Forty-six percent of respondents described themselves as dog people, while 12 percent said they were cat people. Almost 28 percent said they were both and 15 percent said they were neither.

-Dog people were generally about 15 percent more extraverted, 13 percent more agreeable and 11 percent more conscientious than cat people.
-Cat people were generally about 12 percent more neurotic and 11 percent more open than dog people."
