Y'know, the fact that they mention astronauts in Zootopia means they have some kind of space program, which begs the question of how advanced they are as far as space travel goes- do the Zootopians have their own version of the ISS? have they been to the moon, or even established a moon base? Do their space programs favor certain species over others for spacefaring? Small animals like rats and fennecs would require fewer resources and cost less to lift into space, but more amphibious mammals like hippos or seals would probably adapt to microgravity better, having lived most of their lives swimming just as real-life astronauts train underwater.



If they make a sequel to Zootopia I'd want it set in space just to see what they do with it.
