2024 Hardcover Reprint of the 1928 Edition. Facsimile of the original edition and not reproduced with Optical Recognition Software. Millions of Cats is a children's picture book written and illustrated by Wanda Gag in 1928. The book won a Newbery Honor award in 1929, one of the few picture books to do so. It is perhaps the oldest American picture book still in print. The hand-lettered text, done by the author's brother, tells the story of an elderly couple who live comfortably, but realize that they are very lonely. The wife wants a cat to love, so her husband sets off in search of a beautiful one to bring home to her. After traveling far away from home, he finds a hillside covered in "cats here, cats there, Cats and kittens everywhere."

Wanda Gag pioneered the double-page spread in this book. Writer and reviewer Anita Silvey explained, "She used both pages to move the story forward, putting them together with art that sweeps across the entire page spread: her favorite illustration fell in the center of the book - with the old man carrying cats against the rolling hills." This book remains popular with children, parents, and critics alike. In 1001 Children's Books You Must Read Before You Grow Up, Kaylee Davis calls the book an "enchanting tale", and says "Gag's charming, folk-art style, simple black-and-white illustrations, lyrical language, and catchy refrain that children will happily repeat with each reading, make this a family favorite."
