Welfare science for companion rabbits emphasizing their strong social needs, bonding requirements, and the welfare consequences of single rabbit housing.
Companion rabbit welfare is substantially compromised by the persisting norm of single rabbit housing — a practice inconsistent with the social biology of a species that evolved in complex social communities. Rabbits in the wild live in warrens where constant social contact, mutual grooming, shared vigilance, and play behavior characterize daily life. A rabbit kept alone cannot engage in any of these social behaviors regardless of human companionship provided: humans cannot provide the conspecific contact that meets rabbits' social needs. Research consistently shows that paired rabbits have lower stress hormones, spend more time in positive behavioral states, and live longer than singletons. Bonding rabbits is a welfare challenge — introductions must be carefully managed to prevent fighting, typically involving neutral territory introduction, gradual proximity increase, and neutering of both animals. However, the welfare benefit of successful bonding is clear and substantial: bonded rabbits engage in continuous mutual grooming and social contact that fundamentally transforms their daily experience. The lifespan commitment of 8-12 years means that rabbit welfare decisions made at adoption have decade-long welfare implications for both animals in a bonded pair.
