I wonder how much of this is an introvert/extravert thing? I mean, the article already points out that dog people will likely have more friends and cat people are more likely to be single, so I suspect the difference in preferences may depend on that aspect of someone's personality. Cats are perfect for introverts; they look after themselves, don't tend to do much in the day, don't need walks and hence can be mostly left alone (or left to sit next to you) while you browse the internet or work at home. Dogs require more excercise, commitment, etc. So if you gain energy from being around others, what better way than to go for two walks a day round the streets/local park? So extraverts likely choose dogs, and introverts likely choose cats.
