Not so long ago, in order to dispel the melancholy of some great prince, a noted and ingenious actor constructed an instrument such as this. He took live cats all of different sizes, and shut them up in a kind of box especially made for this business, so that their tails, stuck through the holes, were inserted tightly into certain channels. Under these he put keys fitted with the sharpest points instead of mallets. Then he arranged the cats tonally according to their different sizes, so that each key corresponded to the tail of one cat, and he put the instrument prepared for the relaxation of the prince in a suitable place. Then when it was played, it produced such music as the voices of cats can produce. For when the keys, depressed by the fingers of the organist, pricked the tails of the cats with their points, they, driven to a rage, with miserable voices, howling now low, now high, produced such music made of the voices of the cat as would move men to laughter and even arouse shrews to dance.

Sometimes when people misunderstand a product or feature they give you ideas for how it might work or for another product or feature. Creativity sometimes comes just from not knowing something. Another reason it’s important to listen, you never know how new ideas will arrive.
