Allerleirauh (German "All-Kinds-of-Fur", sometimes translated as "Thousandfurs") is a fairy tale recorded by the Brothers Grimm. Since the second edition published in 1819, it has been recorded as Tale no. 65. Andrew Lang included it in The Green Fairy Book.
It is Aarne-Thompson folktale type 510B, unnatural love. Others of this type include Cap O' Rushes, Donkeyskin, Catskin, Little Cat Skin, The King who Wished to Marry His Daughter, The She-Bear, Mossycoat, Tattercoats, The Princess That Wore A Rabbit-Skin Dress, and The Bear. Indeed, some English translators of Allerleirauh titled that story Catskin despite the differences between the German and English tales.
