It’s National Cat Day, and the art world is apparently celebrating in full force—hardly surprising given the growing popularity of the Internet’s favorite animal among artists and art lovers, as evidenced by such phenomena as the Walker Art Center’s yearly festival devoted to cat videos.

Sotheby’s, for instance, is auctioning off a massive 1891 Carl Kaler painting, six feet tall and eight-and-a-half feet wide, that features no less than 42 adorable cats. This fabulous feline masterpiece is expected to fetch $200,000–300,000 at the European art auction on November 3.

Artists from Leonardo da Vinci to Hieronymous Bosch to Balthus have all incorporated cats into their works, leaving no shortage of material for art institutions looking to capitalize on the trending hashtag #NationalCatDay on social media.

New York’s Metropolitan Museum of Art has an entire Pinterest board devoted to cats, while the Harvard Art Museum suggests a visit to see Ernst Ludwig Kirchner‘s Self-Portrait with Cat. Over in the Meatpacking district, by comparison, the new Whitney Museum of American Art spotted a striped gray cat enjoying a stroll on the nearby High Line.

For a look back at artnet News’s previous cat-centric coverage, check out art historical cat portrait book Cats Galore, these drawings prominent politicians as cats, this brilliant fat cat art meme, and billionaire Mark Cuban’s $10,000 cat doodles. We’ve also drawn up a list of our favorite cat paintings from art history.

Regardless of whether or not you have a cat to curl up with this afternoon, have a happy National Cat Day with these cat-filled posts by some of our favorite institutions!
