My Catmate

In ancient Chinese and foreign legends, there is a saying that cats have nine lives and cats can live a million times. We found cats throughout history - from ancient Egyptian to Western Han Dynasty to mural totems. The great poets. Li Shang Yin, Huang Ting Jian, and Lu You have all left poems for cats. It makes people feel a sense of reincarnation.
What is the mission of the cat, and what kind of fantasy story happened between the cat and the five boys?
