In Chapter 9 of "Animal Farm", how do the conditions for the pigs improve, and how do conditions for other animals deteriorate?
In Chapter 9, "all rations were reduced, except those of the pigs and the dogs". When all four sows gave birth to litters obviously sired by Napoleon, they were given special instruction in the farmhouse kitchen by Napoleon himself, and took their exercise in the garden. It was decided that a schoolroom would be made in the garden just for the piglets, and that the other animals would have to labor to make it. It was also laid down as a rule around this time that "when a pig and any other animal met on the path, the other animal must stand aside", and that "all pigs...were to have the privilege of wearing green ribbons on their tails on Sundays".
Rations were again reduced two months after the first reduction, but "the pigs seemed comfortable enough, and in fact were putting on weight if anything'. Later, it was announced that "all barley would be reserved for the pigs", and the news also leaked out that "every pig was now receiving a ration of a pint of beer daily, with half a gallon for Napoleon himself, which was always served to him in the Crown Derby soup tureen".
In a final chilling event, when Boxer is taken away to the horse slaughterer, the pigs have a raucous party with money they reportedly received from an unidentified source. It is undeniable that the funds were gained from the sale of Boxer's carcass to the glue makers.
In chapter nine the pigs are taking over Animal Farm. They are getting fatter and there are more of them. The other animals are having to work harder and the field which was set aside for the "retirement" of the older animals has been turned into a barley field. The pigs start a school for their young, they brew their own beer, and they use the dogs as their security force. The animals get their rations cut and they are working harder than they ever had to work under the Jones. Napoleon declares that the farm is now a republic and names himself as President. He uses Squealer as his propaganda leader and when the animals seem to complain there are more meetings with more speeches and more slogans are changed.
"Moses, the raven, returns to Animal Farm with his tales about Sugarcandy Mountain, which he tells to the starving, overworked animals. His visions of the place where they will go when they die keep the believing animals happy. Although the pigs declare his stories to be lies, they allow him to remain without working, and they give him an allowance of beer every day."
