Query: Comment on `Observation of a quantum Cheshire Cat in a matter-wave
  interferometer experiment', Nature Comm. 5, 4492   It is shown that a classical experiment using an ordinary cat can reproduce
the same results and it is argued that the quantum nature of the phenomenon
could be revealed instead by making an experiment that detects cross-moments.
