Mr. Mistoffelees was known for his sparse talk. His dramatic flair required few words, of his own, at least. Rum Tum Tugger was one of the few to ever hear that quiet voice, that spectacular drama in his fellow performer.
In the middle of the day, when no sensible cat was awake, that quiet voice would erupt in an all too loud yowl. Only the Tugger knew that it was no queen that made him yowl. It was no queen that made him scream with pleasure, the pleasure of a successful mating. Yes, only the Tugger heard firsthand that howl.
