Rabbits are highly social animals that require the companionship of another rabbit. Solitary housing causes chronic psychological distress and is incompatible with good welfare.
The solitary housing of rabbits represents one of the most pervasive welfare failures in companion animal keeping. Rabbits denied social contact exhibit boredom, anxiety, and reduced lifespan. The bonding process itself requires patience and behavioural understanding — rushing introductions causes aggression and trauma. However, the welfare dividend of a successful bond is substantial: rabbits spend more time in positive behavioural states, engage in mutual allogrooming, and show lower stress hormone levels. Shelters, vets, and welfare organisations have a responsibility to guide owners towards paired housing as the default standard, not an optional extra.
