His work is very interesting but it is hard. Sometimes it is dangerous, too. Every morning the zoo keepers have to get up at five to prepare the food for the animals. Each kind of animal is given special food. For example, the lions must be given meat; the deer must be given grass and leaves; and the parrots must be given fruit and nuts. Sometimes some animals won't let the others eat their food. If this happens,  each of them must be fed separately(分离地) .Every morning each cage must be washed by the zoo keepers.
