Rabbits are highly social animals that suffer significantly when kept alone, and proper bonding of companions is essential for their welfare, though it requires patience and careful management.
Many pet rabbits are kept in isolation in small hutches without appropriate social contact, which represents a serious welfare failure. Solitary rabbits show higher stress hormone levels, less natural behaviour, and are more prone to depression-like states. Bonding a companion requires time, appropriate facilities, and willingness to manage the process carefully, but the welfare benefits are substantial. Neutering both animals before bonding is strongly recommended to prevent aggression and unwanted reproduction.
