Ketzel, the Cat who Composed is a children's picture book by Lesléa Newman.

Based on a true story, it is about the friendship between Moshe Cotel and a kitten, Ketzel, who composes a musical piece that Cotel enters into a music competition and receives a special mention.

Booklist gave Ketzel a star review, wrote "this delightfully told story is unlikely and adorable in equal parts.

Bates' watercolor, gouache, and pencil illustrations feature an unanthropomorphic kitty whose inquisitive and quizzical nature will be familiar to all cat owners."

"[2] and Publishers Weekly, in a star review, wrote "a lovely tale of cross-species affection and creativity".
