 FACT: Ferrets do make sounds as heard in the movie; however,  generally, they are as quiet as rabbits. However when excited over a  new experience or playing with other ferrets or their owner it is  quite common to do what owners term "their happy dance" and they  often make sounds very similar to that heard in the movie. That  said, the "whining" sounds made near the end while "left" behind the  closed door to the sidewalk is not normal.
