THE SEVEN COMMANDMENTS
1. Whatever goes upon two legs is an enemy.
2. Whatever goes upon four legs, or has wings, is a friend.
3. No animal shall wear clothes.
4. No animal shall sleep in a bed.
5. No animal shall drink alcohol.
6. No animal shall kill any other animal.
7. All animals are equal.
The seven commandments are listed above; these were copied from enotes summary of Chapter 2. To differ with those of Post #3, Napoleon has some of the commandments altered later, not in Chapter 2. He usurps power in Chapter 5.
Now, the question asks for the nine vices, not the seven commandments. As Post #1 mentions, these are in Chapter 1 and enumerated by Old Major who instructs the animals to never adopt Man's ways even after they conquer him: "All the habits of Man are evil." Unfortunately, Napoleon does not heed the warnings of Old Major.
