I'm gonna go with dogs on this one, because cats to me seem like drama queens. They prance around looking for attention in an almost Paris Hilton sort of way, the males piss everywhere except the litter box, and if they don't like you, well youre screwed cause they will make your life as miserable as possible. Dogs are loyal, friendly, don't require a litter box, and mostly just lie about minding their own business. Go Dogs!!
