This triumph of ingenuity was designed to lend merriment to the street pageant in honor of Philip the Second, and is described by Juan Cristoval, a Spaniard in attendance upon the King.
"'The organ,' says Cristoval, 'was carried on a car, with a great bear for the musician. In place of pipes, it had twenty cats separately confined to narrow cases, from which they could not stir. Their tails were tied to cords attached to the keyboard of the organ. When the bear pounded the keys, the cords were jerked, and this pulled the tails of the cats, and made them mew in bass or treble notes, according to the nature of the airs.'
"Such an invention could have afforded, at best, but doubtful entertainment; yet the cat organ was so widely appreciated that German humourists undertook to alter and improve it; and after a time a choice variety of instruments were constructed, in all of which cats were induced by some well applied torture to furnish forth the necessary music."
Or, from

"In keeping with Darnton's methodology and subject matter we might want to look at the cat piano. Athanasius Kircher first wrote about it in his great *Musurgia universalis* of 1650, and it has reappeared occasionally since. In order to raise the spirits of an Italian prince burdened by the cares of his position, a musician created for him a cat piano. The musician selected cats whose natural voices were at different pitches and arranged them in cages side by side, so that when a key on the piano was depressed, a mechanism drove a sharp spike into the appropriate cat's tail. The result was a melody of meows that became more vigorous as the cats became more desperate. Who could not help but laugh at such music? Thus was the prince raised from his melancholy [1].
"The cat piano confirms Darnton's discovery that most early modern Europeans found the torture of cats funny. It also illustrates Kircher's fascination with the relationship between the art of music and the natural production of animal sounds. But for us it is an instrument that has mercifully been forgotten."
To which all I can say is....OUCH!!!
