I wonder who decides what sorts of animals are kept in the Zoo? You expect to see a lot of monkeys, rhinos, and lions, but you rarely see oxen, sheep, deer or geese, probably because these can be seen commonly enough in the wild. Each day large delivery of food arrives for the beasts to eat. Not expensive items like salmons or trouts, but ordinary things like potatoes and tomatoes ;. although the pandas like bamboos. The whole family, men, women and children can take photos or make videos of them eating with their paws and teeth, since animals do not use knives and forks to eat.
