This cat either has something in his ear, or he is really feeling the music of Jeff Hanneman, Dave Lombardo and Kerry King- otherwise known as mother effing Slayer. And can you blame him? What music better to express his cat rage at the world. Eminem maybe. Its possible more cats love Metal but unfortunately most cat owners probably aren't playing it. Cats are much more likely to hear their people playing Tracy Chapman, Alanis Morissette and Celine Dion (the male cat owners).
