There is an old Lancashire folktale about a little tomcat named Dildrum. He was supposedly the adored pet of the local blacksmith and his wife, who were both unaware that their furry friend had an interesting secret.
One night the blacksmith had been dozing by the fire, his cat curled up on his knee. Suddenly he was awoken when a black cat fell down the chimney and screamed "Tell Dildrum Doldrum's dead!" With that he darted back up the chimney.
Little Dildrum woke with a start and much to his owner's surprise, cried out "Did you say Doldrum's dead?" and disappeared up the chimney himself, never to be seen again. Doldrum, you see, was supposedly the king of all cats and Dildrum, his heir.
