A murky verdict III

This has been an unexpected new routine this holiday season.  Whenever I visit my brother's cat, Lily, Jim Nabors has to be singing at least one Christmas carol on SiriusXM.  On Thursday, it was "O Little Town Of Bethlehem."  This was Lily's reaction:

She might not have been reacting to the vocals; after all, Nabors sings a perfectly credible rendition.  It might have just been the odd coincidence of a Nabors Christmas carol playing whenever I visit.  One concept that psychology instructors teach college students is that correlation does not imply causation.  Now, however, I'm wondering.
