Rabbits are highly social animals that thrive in bonded pairs or groups, and solitary housing is now recognised as a significant welfare problem that causes chronic stress and boredom.
Rabbits are highly motivated to seek social contact and show clear signs of distress when isolated. Solitary rabbits frequently develop stereotypic behaviours such as bar-biting and excessive grooming, indicating poor psychological welfare. They are also more likely to show fear responses and less likely to explore their environment. Bonding two rabbits requires patience and appropriate introduction techniques, but the welfare benefits are substantial. Neutering is essential before bonding to prevent aggression and unwanted reproduction. The shift in advice toward obligatory social housing reflects a much better understanding of rabbit behavioural needs.
