What do you suppose the predators eat? They live in harmony with their prey, so how would their food be provided? Would they still have an abattoir/farm? That's like us living side by side peacefully with cows, pigs, and sheep while farming their families (potentially) Lol.
shareThis question has been asked and answered again, again, and again....
They eat insects, vegetable proteins, and fish. Hints to this can be seen when Judy is going into Zootopia. There's a fish store in Tundra Town that can quickly be seen and when Nick and Judy are waking in the ally a box laying on the ground says bug-a-burger.
How boring lol
Thanks for answering :)
