This IS a weird question! In my opinion, everyone knows which they prefer. For me, it will always be a cat. And telling people "a dog would be easier" is WAY wrong and inaccurate. Dogs have to be walked to go to the bathroom. Cats just need a clean kitty litter box.
People who think cats are standoffish are way wrong as well. My cat is my best friend. He will always be near me, if he is awake. I keep him inside for his safety and that does not bother him at all. He is extremely affectionate, and loving. The things I dislike about dogs include how they smell (yuck! Wet dog smell!) and how gross their behavior can be. But it all depends on how YOU see these things.
