Rabbits are highly social animals that suffer significantly when housed alone, making appropriate companionship a core welfare requirement.
The welfare of solitary rabbits is significantly compromised compared to those with appropriate companions. Without a bonded partner, rabbits lose the behavioral outlets for social grooming, mutual resting, and the sense of security that comes from group living. Behavioral indicators of poor welfare in solitary rabbits include over-grooming, attention-seeking, or conversely withdrawal and reduced activity. The belief that human attention substitutes adequately for rabbit companionship is not supported by behavioral evidence. Successful bonding of rabbits requires patience, appropriate introduction protocols, and in most cases neutering to reduce hormonal aggression.
