 Sylvester the cat is one of the great, underrated performers. He s certainly underrated by Elmer Fudd who only wants a good night s sleep, not a late-night opera from a caterwauling cat. Elmer s shoe to the cat s noggin ends the kitty s Rossini performance. But that unkind gesture makes him mad; and for his next performance he clomps up and down the stairs doing Liszt s "Hungarian Rhapsody." This means war. Elmer throws books at him, ties him up, feeds him alum and tries to blow him up with dynamite. The kitty retaliates with a greased staircase, a floor full of thumb tacks for Elmer s bare feet and a surprising ability to chase him into the hereafter. Meanwhile, a dumb-looking cat with an unexpectedly beautiful female singing voice, becomes an unwitting participant in this mess. "You Never Know Where You re Goin  Till You Get There" sings Sylvester; and that proves true for him, the tabby and especially Elmer.
