This is Marmaduke the cat.  Marmaduke has a very red coat and is a constant companion to Professor Gett.  He happily plays with Buster, the Professor’s dog.  HM Queen Charlotte has two of Marmaduke’s kittens who live at the palace.  The problem is that sometimes they make King Harold’s eyes stream with tears because he is allergic to cats.  The elves in the cave are trying to find a herbal cure for him.
