However, the book does also mention or feature other animals in a supporting role:
* Hawks: Predatory birds that pose a constant threat to the rabbits.
* Foxes: Another predatory animal that hunts the rabbits.
* Badgers: Larger mammals that are generally hostile towards the rabbits, though some individual badgers are more peaceful.
* Stoats and Weasels: Smaller, more agile predators that are also dangerous to the rabbits.
* Dogs: Domesticated dogs, usually representing the dangers posed by humans.
* Cats: Like dogs, they represent the dangers of human companionship.
* Mice and voles: Small rodents that are part of the rabbit's ecosystem.
* Owls: Predatory birds that are occasionally mentioned.
The book primarily focuses on the rabbit characters and their experiences, but it also uses other animal species to depict the harsh realities of the wild and the dangers faced by the rabbits.
