Meow! It’s National Black Cat Appreciation Day. Various superstitions mean that black cats are often the last to be adopted, and are more likely to be abandoned. Russian avant-garde artist Natalia Goncharova painted this abstracted version of two feline companions and their tabby friend while developing a fusion of Cubo-Futurism and Orphism known as Rayism, which focused on light refraction and movement. She is currently the subject of a retrospective at Tate Modern, until 8 September.
