      In St. Petersburg's famous Hermitage Museum...guarding the Czar's jewels, the precious paintings and sculpture...deep in its cellars...live some 70 fat cats...former street felines...but now with their own infirmary and 3 full-time volunteers.
      They guard the valuable art works...from ever hungry and destructive rodents.

      And...they are also employee morale boosters...keeping museum workers kinder...and gentler.
