Zootopia and Kung Fu Panda take place in the same universe, probably.
Different times though. I imagine Kung Fu Panda happened in like the ancient past, while Zootopia is in the near future
Different places too. Kung Fu Panda takes place in China, a diverse place where mammals, insects, reptiles and birds all live together.
Zootopia is some secluded futuristic place of only mammals.
