There really isn't an antagonist because every one loves cats. No one can hate a loving cat. If I had to find an antagonist, I would say it would be mother nature. This takes place during the farm crisis causing people to be in bad moods and also it causes people that have fallen in love with Dewey to move away and not experience the love a cat. Mother nature is uncontrollable and has both positives and negatives. The farming crisis caused two very different effects. It brought depression and hard times, but it also brought families and friends together.
