Rabbits are highly social animals with complex needs that are best met in properly managed group housing, but colony systems require careful introductions and ongoing monitoring to prevent conflict.
The social nature of rabbits is fundamentally incompatible with the solitary housing that remains common in both companion and laboratory settings. Rabbits housed alone show higher cortisol, reduced positive welfare indicators, and behavioral patterns consistent with chronic loneliness and boredom. Properly managed social housing — with bonded partners or compatible groups in appropriate space — transforms rabbit welfare. The bonding process requires patience and proper management, and occasional incompatibilities do occur, but these are manageable challenges rather than reasons to default to solitary housing. Legislative change in several European countries now mandates social housing for laboratory rabbits, recognizing the welfare evidence. Companion rabbit owners should similarly prioritize bonded pairs or groups.
