The animals’ rise to power is dangerous for the humans because Mr. Jones lost his farm, and the other humans are afraid that their own animals will also revolt.
Revolution can be contagious. When one group gets up the nerve to overthrow its leaders, nearby leaders often get nervous that the same thing will happen to them. This is the case in Animal Farm. The animals overthrow the humans and kick them out, taking over the farm. This is trouble for the neighboring farms. They are worried that their animals will do the same.
Frederick and Pilkington, the neighbor farms, do not like each other. Yet they worry about Animal Farm.
Nevertheless, they were both thoroughly frightened by the rebellion on Animal Farm, and very anxious to prevent their own animals from learning too much about it. (ch 4)
The humans spread rumors that there is cannibalism, hunger, and abuse on Animal Farm. They hope their animals will believe them, and not do the same thing. However, the humans eventually have to begin trading with Animal Farm’s animals, trying to turn the situation to their advantage.
The humans are opportunists, and have two goals when it comes to the animals. They want to prevent their own animals from rebelling, and they want to take advantage of the animals in whatever way they can.
