<Li> The sheep--They show limited understanding of the Animalism and the political atmosphere of the farm; yet nonetheless they blindly support Napoleon's ideals with vocal jingles during his speeches and meetings with Snowball . Some commentators have compared the sheep to representations of state controlled press . Their constant bleating of "four legs good, two legs bad" was used as a device to drown out any opposition; analogous to simplistic headlines used in printed media of the age . Towards the latter section of the book, Squealer (the propagandist) trains the sheep to alter their slogan to "four legs good, two legs better", which they dutifully do, symbolizing the state manipulation of media . </Li> <Li> The hens--The hens are promised at the start of the revolution that they will get to keep their eggs, which are stolen from them under Mr Jones . However their eggs are soon taken from them under the premise of buying goods from outside Animal Farm . The hens are among the first to rebel, albeit unsuccessfully, against Napoleon . </Li> <Li> The cows--The cows are enticed into the revolution by promises that their milk will not be stolen, but can be used to raise their own calves . Their milk is then stolen by the pigs, who learn to milk them . The milk is stirred into the pigs' mash every day, while the other animals are denied such luxuries . </Li> <Li> The cat--Never seen to carry out any work, the cat is absent for long periods and is forgiven; because her excuses are so convincing and she "purred so affectionately that it was impossible not to believe in her good intentions ." She has no interest in the politics of the farm, and the only time she is recorded as having participated in an election, she is found to have actually "voted on both sides ." </Li>
