Mrs. Frisby and the Rats of NIMH

Mrs. Frisby and the Rats of NIMH Theme of Society and Class

In many novels, issues of class and society have to do with money, wealth, and poverty. In Mrs. Frisby and the Rats of NIMH, however, money and wealth aren't so much the issue as are questions of belonging and not belonging. The NIMH experiments have changed the rats so deeply that they are unable to fit in with their own kind any longer, but it is also unclear to them whom they can fit in with. They are outcasts from rat society. Since they can't just give up, the rats are forced to figure out how to build an entirely new society and to make up the rules that will govern it.

Questions About Society and Class

  1. What is it about the rats that makes the other animals on the farm want to keep their distance?
  2. Nicodemus tells Mrs. Frisby that the rats have roles, but not titles. What does this tell you about the rats' society? Do you think it's a good thing that they don't have titles or do you foresee problems? 
  3. The rats think that they are one thousand times more intelligent than regular rats. If you had a choice to expand your intelligence by this much, would you do it? Why or why not?

Chew on This

Try on an opinion or two, start a debate, or play the devil’s advocate.

The NIMH experiments give the rats an amazing chance to completely reinvent their society.

These rats don't have a chance! Without clearly defined class and social rules, they will collapse into total rat chaos.
