If human beings become slaves of animals

In the eyes of animals, their range of entry and exit is always so small. No, God turned people to Mars and let the animals dominate the world.

"Hey screaming..." The pigs couldn't wait for breakfast, and they jumped out of the pigsty and swayed to the feed field. The lions and tigers of the zoo also came out. To make matters worse, a sparrow raised by the president became the president of the animals! It’s too big, it’s big...

Even though no one is there, the animals are doing well: the lion becomes the vice president, the tiger becomes the bodyguard; the chicken is still laying eggs in the chicken farm, and the cockroach is still grinding. However, some dogs did not appreciate it. When some birds "had" a "entry permit", the dog refused to "Wang Hao" unceremoniously.

They also divided the territory: the world of the lion is this piece of wheat, the territory of the scorpion is the whole mill, the territory of the pig and the dog are in the farmhouse, the monkeys become people, and they live in the house of the people. All of them are in good order, no worse than people in time.

What changes will happen when people come back?
