Researchers at the University of Nevada conducted a study of 1,210 online daters based in the U.S. (61% of which were women) to figure out how pet ownership shapes our love lives. They found that single women are more than twice as likely as men to admit to being attracted to someone because they had a pet. The reasoning? It's not just cuteness; if you take care of your four-legged pal, you'll probably take care of them.
