Picture books are great for engaging readers, combining images and words to make comprehension easier and vividly convey the author's intentions. This is why we chose the picture book format for conveying rational cat-keeping knowledge. "Evolution of Cat" is a popular science picture book about the history of cats and terrestrial ecological protection. It uses the perspective of house cats to explore the changing human-cat relationship and the ecological impact of cat behaviors. The book aims to guide readers in rational cat interaction, presenting the history of cats chronologically and incorporating the author's own cat and internet memes. Through digital illustrations, the book serves as both a historical science education tool and a promoter of ecological protection.
