in short, cat owners are the neurotic depressive visionary types, while dog owners are the golden standard of society

There are sound reasons to suspect that the preference for dogs or cats reflects some underlying human personality differences. Certainly the relationship between cats and humans has always been quite different than the relationship between dogs and people. This reflects the behaviors that both species have kept from their heritage prior to domestication. In the wild, cats are usually solitary hunters and often are active mostly at night. In contrast, wild canines are usually sociable pack animals that work in groups and are active between dawn and dusk. Our domestic dogs retain this need for social interaction to the degree that without a master and a family, a dog seems unhappy--almost lost. Dogs will intrude on a person's ongoing activities if they are feeling lonely and want some company or play. Cats, on the other hand, are often invisible during the day, seeming only to appear in the evening, especially if that is when they are fed. Cats will occasionally engage in social activities or play with people, but their interest is limited. Usually, after only a few minutes, cats will abandon the game and wander away. Dogs on the other hand, will often engage in play, like fetching a thrown ball, for hours at a time, and it is usually the human that quits the game first.
Recently, Sam Gosling, a psychologist at the University of Texas in Austin and his graduate student Carson Sandy conducted a web-based study in which 4,565 individuals were asked whether they were dog people, cat people, neither or both. The same group was given a 44-item assessment that measured them on the so-called Big Five personality dimensions psychologists often use to study personalities.
Gosling summarized his results saying, "There is a widely held cultural belief that the pet species -- dog or cat -- with which a person has the strongest affinity says something about the individual's personality, and this research suggests there are significant differences on major personality traits between dog people and cat people."
Just on the basis of the nature of dogs being more sociable than cats, one might expect that the personalities of dog lovers would also reflect higher sociability. The results showed that dog people were generally about 15 percent more extroverted and 13 percent more agreeable, both of which dimensions are associated with social orientation. In addition dog people were 11 percent more conscientious than cat people. Conscientiousness involves is a tendency to show self-discipline, to complete tasks and aim for achievement. The trait shows a preference for planned rather than spontaneous behavior.
In comparison cat people were generally about 12 percent more neurotic, however they were also 11 percent more open than dog people. The openness trait involves a general appreciation for art, emotion, adventure, unusual ideas, imagination, curiosity, and variety of experience. People high on openness are more likely to hold unconventional beliefs while people with low scores on openness (dog people) tend to have more conventional, traditional interests.
