I've been reading this story to Preschoolers, Kindergartners, 1st, 2nd, 3rd, and 4th graders for three years now. It is a hit everytime. It is a good version of how the animal zodiac came to be without any religious theme which makes the public school system happy.
I have found some great books for children on China and Vietnam. My students from those areas will love them and my other students will be able to appreciate the culture better. We all benefit from learning more about each other. Cat and Rat helps with an interesting entertaining story. The zodiac is always intriguing to everybody.
