On the book Animal Farm (author George Orwell), what reasons do the animals have for staying on the farm or just going on with their lives as normal? What reasons do they have to rebel against Jones' cruel ways?

The animals were used to Jones' cruel ways, so they didn't see a terribly large need to rebel until the pigs suggested it. The reasons the pigs use to entice the other animals to rebel include but are not limited to harsh working conditions, lack of food and resources, and lack of freedom.
