Another way that George Orwell uses irony in Animal Farm is how the animals are happier after the rebellion even though they are doing more work. They were happier than they had “[ever] conceived possible to be” (46). This is even though they “toiled and sweated” (45) and were “met with many difficulties” (46). I think that this is because they can control everything. For example, if they are tired, they have the ability to decide to rest. Afterwards, once they think they're well rested, they can work again. Even though they have to work more in the long run, the freedom of choosing their own action of when they want to do something and how they want to do that is an improvement from before the Rebellion.
