"Cat and Bird" was painted by Paul Klee in 1928. It is an oil and ink on canvas, and is in the collection of The Museum of Modern Art in New York City. Although not all of Paul Klee's paintings are in the public domain, "Cat and Bird" has been in the PD in the United States since the 1990s.

Paul Klee is considered both a Swiss and a German painter. His highly individual style was influenced by movements in art that included expressionism, cubism, and surrealism. He and his colleague, the Russian painter Wassily Kandinsky, both taught at the German Bauhaus school of art, design and architecture. Wikipedia, the online encyclopedia, says: "His works reflect his dry humour and his sometimes childlike perspective, his personal moods and beliefs, and his musicality." ~ He was also a cat lover.
