Kanga is a character in A. A. Milne's books Winnie-the-Pooh (1926) and The House at Pooh Corner (1928). A female kangaroo and the mother of Roo, she is the only female character in Milne's Pooh books. Kanga and Roo are the only pair of animals of the same species in the books, and their close relationship is emphasized by the combination of their names ("Kanga-Roo"). The maternal instinct, in addition to Kanga's desire to always keep Roo close to her, in her pouch, is also evident in Kanga's willingness to adopt the newly arrived Tigger. Source: Wikipedia (en)
