★ "Underwood and Rueda maintain the droll narration and spare visual humor of the previous books as Cat guides eager kittens through music (electric guitars are involved), building time (a "fountain that spouts fish" is involved), and art (major cleanup is involved). There's plenty to giggle over." --Publishers Weekly (starred review)

"Kids will think it is just purrfect." --The Washington Post

"The interplay between unseen narrator and substitute teacher Cat fuel the humor, and Claudia Rueda's adorable, deadpan illustrations carry the simple story." --Common Sense Media

"In a clean-up worthy of The Cat in the Hat, the kittens pitch in to save the day. . . . Cat's droll expressions and signs are highlights . . . [and] readers may get a kick out of imagining what adventures they might have with their own substitute teachers." --Kirkus

"Whether new to this series or a seasoned fan, this amusing read-aloud has much to offer the younger back-to-school crowd." --School Library Journal

"Underwood's clever use of page-turns and comedic timing . . . deliver a droll story about the joys and challenges of teaching." --The Horn Book
