In this Dr. Seuss classic, a mischievous, singing cat transforms a dull, rainy afternoon into a magical and just-messy-enough adventure for a brother and his sister. This jovial feline trashes the siblings' house searching for his "moss-covered, three-handled family gradunza" and severely upsets the pet fish. Just when the house is in complete disarray, the children's mother returns home. Will the house be clean before she opens the front door? With its simple and often single-vowel vocabulary, the book has been called a must for any child's library.
