Melanie Walsh, creator of Do Pigs Have Stripes? and Do Monkeys Tweet? shows her skill in reaching the youngest readers. Walsh shows differences between pairs of animals and then shows how they are similar.

Lions are big and have hairy manes.
Kittens are small and fluffy. But . . .
they both have scratchy claws!

There are birds and bats, sharks and goldfish, penguins and birds—who at first may seem very different, but share similarities, too. Children will love guessing on their own.
