This is not the first time that anthropomorphized animals are used to show the glories and miseries of our society. The technique is as old as humanity and is tied close to a little mouse that became the icon for a major animation film company (and for the 20th century in general) or even further, with the earliest fairy tales.
In the traditionally crafted animated film Ernest & Célestine, it is shown through two main characters, a little mouse and a big bear, outsiders of their respective societies, living in parallel worlds on the surface and in the underground.
