Spaying and neutering companion rabbits provides significant health and welfare benefits, preventing uterine cancer in females and reducing hormone-driven aggression and territorial behaviours in both sexes.
Intact female rabbits face a near-certain cancer death within a few years; this is a profound preventable welfare harm in companion animals. Intact male rabbits experience frustration from reproductive drive in environments where mating is impossible. Hormone-driven territorial behaviour disrupts bonding with other rabbits, denying companionship essential for rabbit wellbeing. Neutering enables stable pair bonds, prevents fatal cancer, and reduces stress from hormonal behaviour — representing one of the highest-value welfare interventions available to rabbit owners.
