We are starting a cat ranch and taking one hundred thousand cats
  Each cat will have twelve kittens a year
  The catskins will sell for thirty cents each
  One hundred men could skin five thousand cats a day
  We could be dealing a profit of over ten thousand dollars
  But what should we feed the cats?
  We will start a rat ranch next door with a million rats
  The rats will be twelve times faster than the cats
  So we can have more rats to feed each day for each cat
  But what should we feed the rats?
  We will feed the ratsThe carcases of the cats
  After they have been skinned
  Now get this!
  We feed the rats to the cats and the cats to the rats
  And get the catskins for nothing
  We feed the rats to the cats and the cats to the rats
  And get the catskins for nothing
  We feed the rats to the cats and the cats to the rats
  And get the catskins for nothing
  We feed the rats the carcases of the cats
  After they have been skinned
  We feed the rats to the cats and the cats to the rats
  And get the catskins for nothing
  Rats to the cats and the cats to the rats
  And get the catskins for nothing
