People who love animals go to the zoo to see them, but we rarely realize and sympathy the animals' situations. When people talk about the animals they saw in the zoo, the most words that I heard are "They are so lazy and shy, especially the carnivores". As I see, the herbivorous animals are more adaptable than carnivores in the zoo. The herbivorous animals are just keep eating grasses and leaves. They do not care about much as they have enough food. But the carnivores are different.  They are lying on front closing their eyes, and sometimes lift their eyelids. You will alway wondering there are must sometime they lost. The spirit? The happiness? The fierceness? The natural instincts?  There is maybe just one thing to comfort themselves---- the memories.
