I didn't know what to make of this video at first. Though being a cat lover I was totally pleased to see and hear it.
What I didn't know was this is a piece that has been in existence for some time. It is apparently attributed to Gioachino Rossini because it borrows music from his 1816 version of Otello. That, apparently, is about as close as Rossini ever got to writing music for cats.
Regardless of who and when, it's fun to see and hear.
