Dimension Prime(name unofficial) is the universe in which most of the events of Housepets! takes place. It is near identical to the real world, aside from all mammals, birds, and reptiles being sapient and, in many cases, humanoid. However, Bugs and Fish remain unintelligent. Notable locations include Babylon Gardens and River Ridge.
