In this line, the animals are discussing the change in the commandments of Animalism, which they had written on the wall after the rebellion.At first, the commandment clearly stated, "No animal shall sleep in a bed," as a rule against adopting human habits. However, when the pigs start living in the farmhouse and sleeping in beds, they change the rule to say, "No animal shall sleep in a bed with sheets."The animals are confused by this change, but Squealer, the pig who spreads Napoleon's propaganda, convinces them that the change is okay and for their benefit.

In this line, the animals are discussing the change in the commandments of Animalism, which they had written on the wall after the rebellion. At first, the commandment clearly stated, “No animal shall sleep in a bed,” as a rule against adopting human habits. However, when the pigs start living in the farmhouse and sleeping in beds, they change the rule to say, "No animal shall sleep in a bed with sheets."
This change shows how the pigs, especially Napoleon, are starting to break the original rules of Animalism, which were supposed to keep the farm equal. The new rule is a small change, but it shows how the pigs are slowly gaining privileges similar to the humans they once rebelled against.
The animals are confused by this change, but Squealer, the pig who spreads Napoleon’s propaganda, convinces them that the change is okay and for their benefit. This moment shows how the pigs are becoming more corrupt, using language and small adjustments to slowly shift the rules to suit their own desires, while still claiming they are following the principles of Animalism. The animals are unable to see how these small changes are taking them farther from the original idea of equality.
