Bert in wind in the willows?

None of the (vital) animal characters in WITW have proper Christian names. I suppose Mr. Grahame felt the possible assaults of censors as the novel is drawn very realistically for an animal tale. It is essentially an animal cartoon in novel form, a very rare genre, the only other one I can think of was also given an evasive title- Where the Blue Begins- by Christopher Morley- and about a canine yacht club. The characters are the Mole, Rat( called Ratty as a nickname) Badger, and Toad. Toad.,always Mr.Toad, is the top dog, so to speak. There are no female characters of any importance. By the way Bert is Mary Poppins' paramour and sidekick in the film ( not so sure of the play) of that title. Bert has super-powers akin to Mary and poses in various occupations- a sort of Jack of all trades. he is human, though, not an animal character.
