How does Squealer justify the fact that the pigs now sleep in beds?
He says that the pigs must sleep separately from the other animals because they do not want to catch the common animals' diseases.
He says that the pigs are merely testing them out to make sure they are not harmful to the other animals.
He says that the common animals' beds are actually more comfortable than the beds in the farmhouse, so the pigs are sacrificing their comfort by sleeping in the farmhouse.
He says that the rule is actually against sleeping in beds with sheets, since sheets are a human invention.
