Here's why:
* Animal Farm is a satire: The story criticizes totalitarian regimes and their manipulation of language and history. Awards are often associated with power structures and propaganda, which is the antithesis of the animal rebellion's initial ideals.
* Their contributions are acknowledged, but not with awards: Boxer is known for his hard work and dedication ("I will work harder") while Snowball is recognized for his strategic brilliance in the Battle of the Cowshed. These contributions are acknowledged within the narrative but not through formal awards.
* Napoleon's control: The pig, Napoleon, ultimately seizes power and rewrites history to his own advantage. It's unlikely he would bestow awards on those who opposed him, such as Snowball.
So, while Boxer and Snowball are important figures in the story, they are not given any formal awards.
