Yeah, I'm a cat person. I don't have one now, but when I have they've been indoor cats (not out roaming the neighborhood, annoying others with midnight serenades, mating orgies, etc.).
Cats suit me. They're clean, they're funny, they just sit around and watch stuff, they're affectionate if you want them to be but they don't require the attention and effort a dog seems to. They seem (at least the ones I've had) to have a very cool "hey, I'm just over here in the window sill, watching birds and hanging out; lemme know if you need me...oh, and tuna later, right?" vibe about them.
And they're cute.
