Reviews:
"The graphic novel element really sets the "Do You Know?" series apart from other animal fact books. Children will be attracted to the colourful illustrations and hilarious dialogue between the comical characters."
""Do You Know Rats?" cleverly presents numerous scientific facts about rats in a comical graphic-novel format. Throughout the book, the reader learns about the classification, population, reproduction, eating, and behavioural habits of rats. . . Sampar's humorous, colourful cartoon illustrations and speech bubbles bring the scientific rat facts to life by creatively depicting them through the perspective of rats.
Recommended."
