In the U.S., there are more than 78 million dogs and 86 million cats as pets. Thirty-nine percent of households own at least one dog, and 33 percent of households own at least one cat. Just like there are differences between these two common household pets, lots of differences separate dog people and cat people. Typically, the population of male dog people is higher, and there are more female cat people. A dog person is 50 percent more likely to be conservative, whereas cat people tend to skew liberal. Dog people are more likely to be students, but cat people are 17 percent more likely to have completed a graduate degree. Cat people are 29 percent more likely to live in the city, where dog people are 30 percent more likely to live in a rural area.
