Fans of the hit PBS Kids' TV show The Cat in the Hat Knows a Lot About That! are in for a spring-themed treat! In Thump! (the first of two stories in this book), the Cat and Co. learn how rabbits communicate warnings to each other by thumping their feet on the ground, and in The Lost Egg, when Sally and Nick find a strange egg in the nest of a bowerbird, they discover not only that birds lay different kinds of eggs in different kinds of nests, but also that birds are not the only animals who lay eggs! This is a perfect, super-informative read featuring two of the most iconic images of spring and Easter: rabbits and eggs--plus the always-iconic Cat in the Hat!
