First, shoot the cat.  Then have a discount sale on damaged pianos...... 
   The stains are from the acidic reaction to the cat's paws having been in 
the litter box, (or at least, that is what has happened to several of my 
customers, and no, none of them went for suggestion #1).  
    I don't remember any successful way to clean bass strings once they have 
been corroded like this. 
Almost anything you do will damage the sound.
