              Gut stasis is a common presentation seen in
              the pet rabbit, with many di erent causes. Pain
              may occur as a result of gastrointestinal
              distension or, alternatively, gastrointestinal
              motility may be reduced as a consequence of
              pain. Providing ade uate analgesia is therefore
              vital to break the cycle in these patients.
