"A likable hamster narrates this novel for newly independent readers….Birney succeeds in developing the animal’s character without the narrative becoming too cute or contrived. Humphrey's views underscore the importance of knowing the full story before making judgments, and his presence makes a positive difference in the lives of the people he meets. All in all, a winning book that will appeal to children who like tales about animals, school life, and friendship."—School Library Journal

"The story deftly avoids triteness while still feeling breezy and acknowledging deeply felt troubles, such as Mrs. Brisbane's husband’s depression. The pet-care tips punctuating each chapter would benefit any youngster thinking about getting a hamster, but for everyone else, this read is simply good-good-good."—Kirkus Reviews
