This is only a short-answer space but I can make a general statement
Old Major addresses the animals, calling them, “Comrades.” He explains that, because he is getting old and may die soon, he wishes to impart his wisdom. Over his lifetime, he has come to the conclusions that “No animal in England is free” and “The life of an animal is misery and slavery” (28).
Old Major states that animals’ domination by Man is the sole reason they cannot be free, happy, and fulfilled. Man is “the only creature that consumes without producing.” His only job is to be “lord of all the animals,” which makes him “the only real enemy” animals have. Man overworks animals only to rob them of the fruits of their labor, and treats them only well enough to survive and provide more labor. When Man is done with an animal, he slaughters it cruelly.
According to Old Major, Rebellion is the path to freedom. Overthrowing the human race would make animals “rich and free” almost instantly. Old Major begs the other animals to devote the rest of their lives to the cause of Rebellion and to reject the idea that they have co-dependence with Man. Furthermore, the animals must be united in order to overthrow man: “All men are enemies. All animals are comrades” (31). Despite this saying, he is not sure whether wild animals count.
