Poor animals. The fierce animals are all surrounded by the power grid. Although the safety factor is high, they can't see it clearly. Every animal is lazy, and the result of not feeding is that it cannot interact. The place where the small animals are fed is OK, and the small animals who have been hungry for a long time are surrounded in groups. No animal in all places is walking freely, all in the fence. Safety factor first. The place is large, empty, and some are still under construction. Needs to be improved,
