Rabbits are social animals that require a bonded companion for psychological wellbeing, and the process of introducing and bonding rabbits requires patience and skill to achieve stable lasting pairs.
The welfare case for companion pairing of rabbits is strong and well-evidenced. Lone rabbits show measurable stress indicators, higher rates of stereotypic behaviour and reduced longevity compared to bonded pairs. The social bonds rabbits form are genuine and enduring — grief responses following companion loss confirm the depth of these relationships. The bonding process requires investment of time and knowledge to achieve safely, but the welfare return across a rabbit lifespan of 8-12 years is substantial. Rescue adoption of pre-bonded pairs eliminates the bonding challenge while providing optimal welfare for animals who have already formed stable relationships. The single most important welfare improvement available for companion rabbits is ensuring they are never kept alone.
