The runt Fiver foresees the destruction of the Sandleford warren, which is later gassed and bulldozed for a housing development, but the Chief Rabbit dismisses him because the warning comes with no evidence and disrupts a comfortable order. Only his brother Hazel and a handful of others act on it and leave.
Cowslip's warren is sleek, well-fed and artistic because a farmer feeds its rabbits and snares them one by one. The rabbits keep their comfort by never naming the snares and by making art and ritual that turn their losses into something beautiful. It shows how a community that lives off a hidden cost builds a culture of evasion, so that asking where the missing ones went becomes the real taboo.
Hazel is not the strongest, fastest, or cleverest rabbit. He leads by trusting Fiver's foresight, Bigwig's strength, Blackberry's ingenuity, and Dandelion's storytelling, and by asking for help from outsiders like Kehaar the gull and even the mice. His authority comes from knowing whom to believe and when to act, not from personal excellence at any single task.
General Woundwort's Efrafa is safe from predators and hidden from men because it is run as a police state. Rabbits are marked, sorted into guarded groups, allowed out only at set times, and forbidden to leave. Seen this way, the book treats safety and liberty as a trade-off a society actively chooses, and it shows that a system built for survival can hollow out the lives it was meant to protect.
