 According to the storyboard (included as a bonus feature on the  "Looney Tunes" DVD set), this cartoon originally was to have had one  more scene at the end. As Clyde the cat floats via balloon to "Cat  Heaven," the mice are shown inside the house, in front of the  fireplace, roasting cheese clumps (shaped like marshmallows) on  toothpicks. Clyde is seen through the window, blissfully drifting  skyward.
