Should adult muskrats be housed together or separately?

• A. Together
• B. In pairs only
• C. In a colony
• D. Separately

Answer: (B)

Muskrats are social but territorial, and adults can become aggressive when housed with too many conspecifics. Keeping two adults together provides the needed social interaction to reduce stress, while avoiding the conflicts that arise in larger groups. A colony or multiple adults together often leads to fights over space, resources, and dominance, increasing the risk of injuries in captivity. Housing adults separately eliminates social interaction, which can also cause stress or boredom in a rehab setting. Therefore, pairing adults is the best compromise: it satisfies social needs, minimizes aggression, and allows easier monitoring and care. If aggression occurs, or if breeding factors come into play, adjust housing accordingly by separating or rearranging pairs.
