These cats are disgusted
by the way the humans are acting. Humans consider that cats are (ahem)
erotic. In fact, cats are romantic, they sing to their lovers (I mean just
because humans have no taste in music is no reason to criticize us). Some
humans don't even bother to say 'hello'. I feel sorry for the cat in the
left picture: look how horified she is! The one on the right picture is
so ashamed of his head servant that he's hurrying away rapidly.
