Step into reading with the Cat in the Hat in this leveled reader all about different kinds of animal feet! Sally and Nick are having shoe trouble. Sally can't stand up in her mom's shoes, and her dad's are too big for Nick. Not a problem, says the Cat. Feet come in all shapes and sizes, and to demonstrate, he takes them on a trip in the Thinga-ma-jigger to visit some friends: a duck with flat, wide feet good for swimming; a lemur with long, grasping toes good for climbing; and a gecko with tiny hairs on his feet that keep him from slipping. Written specifically for children learning how to read with help, this Step into Reading book about the different ways of "stepping" is based on an episode of the hit PBS Kids preschool science show The Cat in the Hat Knows a Lot About That!
