Today is International Cat Day, a great time to show the cats Escher captured in one of his prints. There are not that many. He often used animals in his work, but his tessellations and metamorphoses mostly feature birds, fish and reptiles. The cats are mainly from his younger years. This is one of those early ones, from when he was 21 years old, around the time he decided to become a graphic artist. On 17 September 1919 he moved to Haarlem. He gets a white cat from his landlady, which would inspire him to produce several woodcuts*. On this one the cat lies on the lap of a man who visited Escher in Haarlem. We do not know who it is. Probably one of his childhood friends, Bas Kist or Jan van der Does de Willebois, or his older brother Nol.
