I have had a longterm phobia towards dogs. I will not easily visit a friend that has dogs, but will freely go to a friend that got cats. When asked to make a choice between the two most popular pets we can see at our home, which one are you going to pick? Why did you say so?
Definitely a cat...or a ferret if that's an option.
I like how cats are mostly self-sufficient, and can take care of themselves for the most part. They don't need a ton of attention, but will demand attention from you when they want/need it.
