When Tracey Emin’s cat Docket went missing in 2002, the “Lost Cat” posters she pasted around her east London neighbourhood were pilfered and valued at £500. Her gallery, White Cube, argued that they didn’t count as works, though some art historians said otherwise. Whomever you believe, they still occasionally turn up on eBay.

It is Emin’s self-portrait with Docket that I love the most, however. (That and her handmade cat photo book, Because I Love Him, a dream art purchase should I ever make it rich.) In the photograph, Docket faces the camera with that deadpan, slightly morose expression that is particular to cats, his impressive whiskers shooting out beyond the artist’s fingers, which frame his face as she nuzzles him from above. It’s a strikingly maternal image, and indeed Emin has in the past referred to the cat, who has sadly now left this earthly plane, as her “baby”. It comes in a long line of artistic depictions of women or girls with cats.
