Spontaneous gastric dilatation-volvulus in two cats.

Gastric dilatation-volvulus in cats is a rare event and appears to occur in 2 clinical settings: in combination with traumatic diaphragmatic hernia (as previously reported) and without a history of trauma or diaphragmatic hernia, as in the 2 cases reported here. Clinicians should consider GDV in the list of differentials for cats with respiratory distress and abdominal distension, even if classic radiographic findings are not present.
