Even the little black-and-white cat, half hidden behind the lid of an earthenware pot, seems to be watching the viewer. Is it also listening to the music, or is it a bit frightened by it? Or is it simply hiding from the thin little dog, enraptured by the music like everyone else?
To me, the cat looks skittery, ready to bolt if necessary. It does not seem to be relaxed. Of course, maybe it just doesn't like the music being played and is merely waiting for a better selection.
