Three adult cats with obstipation due to stenosis of the pelvic canal were treated by symphyseal distraction-osteotomy using an ulnar autograft. The duration of clinical signs before the surgery in the three cats was one, three and 19 months; the first two cats had no recurrence of signs after surgery, and the third had less severe and less frequent bouts of constipation.
