I can't believe I missed this poll. Drat!
I would have voted dogs since I currently have two of them and no cats.
I used to have lots of cats. We had 6 of them, all indoors, at one time, plus a dog and two kids who most likely thought they were cats. I also tend to like dogs more than cats because I need their attention. If you have self-esteem issues, you don't want to rely on any reassurances from cats LOL
