Meanwhile, some bloggers are wondering whether the whole campaign was inspired by this German cat piano from the 1600s. Yes, you read that correctly, "Cat Piano".
This crazy musical instrument was designed in 1650 by Athanasius Kircher, a 17th century German Jesuit scholar.
The piano was designed to raise the spirits of an Italian prince who was too stressed out. The musician would select cats whose voices were at different pitches then arrange them in the pens accordingly. The piano delivered sharp pokes into the tails of the cats.
