Rabbits are highly social animals that suffer from loneliness when kept alone. Proper bonding of rabbit pairs or groups is one of the highest-impact welfare improvements for companion rabbits.
The social welfare of rabbits is among the most consistently underappreciated aspects of companion rabbit care. A rabbit kept alone is missing one of its most fundamental needs. The chronic low-grade stress of social isolation contributes to reduced immune function, shorter lifespan, and behavioral problems. Bonding two compatible rabbits is transformative for their welfare — owners who witness bonded rabbits grooming each other and sleeping together consistently report dramatic behavioral improvements. All rabbits should be housed with at least one compatible companion.
