Many of you already know that bagpipes are powered by a total of four cats. Three of them set off the droning noise while the fourth one is encouraged to make the melody. Its tail is squeezed by an arrangment of holes and levers. Thanks to the marvels of modern miniaturisation, this squeeze box here has no less than thirty two baritone cats. Individual buttons poke the cats in various places. Clearly any instrument this ambitious takes some considerable pumping to keep going.
