In what ways do the pigs emulate men? Why doesn’t it “seem strange” to the other animals?

The pigs now walk on two feet, buy a telephone and have subscribed to several magazines. Napoleon takes to smoking Mr. Jones’s pipe, and the other pigs take to wearing Mrs. Jones’s clothes. Napoleon begins wearing Mr. Jones’s dress clothes and awards “his favorite sow” the privilege of wearing Mrs. Jones’s Sunday dress. One day, Napoleon invites human visitors to tour the farm. That night, the animals spy into the farmhouse and see the pigs dining with the humans. According to Mr. Pilkington’s toast, they are celebrating the end of their bad relations. Touring Animal Farm has impressed him and the other farmers to follow Animal Farm’s example and give their animals more work and less food. Napoleon says he wants to cooperate with the other farms and confirms that he and the pigs co-own the farm’s title-deeds. He states that the animals will no longer be calling each other “Comrade” or marching past Old Major’s skull (a practice he denies understanding anyway). In addition, the flag has been changed to a plain green without the symbols of the Rebellion. Even further, Animal Farm shall again be referred to as “The Manor Farm.” The pigs and humans begin to play poker, and a fight erupts when Napoleon and Pilkington both put down the Ace of Spades at the same time. As the animals witness the pigs and humans quarreling over their poker game, they cannot distinguish between them. This doesn't seem strange to the other animals because Napoleon has successfully removed the memory of Animal Farm from history by rewriting the story to serve his own needs.
