This is a very sciency book for Disney. Cartoon Mickey appears on every page alongside real-life photographs and facts that are more commonly found in National Geographic. The pages are very content-dense, and readers of all ages will learn new facts about many different house pets, including guinea pigs, mice, horses, rabbits, turtles, hamsters, parrots, goldfish, canaries, and, yes, puppies.
This is a Disney science book and it answers lots of good questions, like: "How do cats land on their back?" "Do goldfish get bored?" "Are guinea pigs really pigs?" and so on.
