Abstract: Intestinal obstruction in cats is a disease characterized by intestinal dysfunction and difficulty in transporting contents. It is difficult to distinguish between mechanical obstruction and functional obstruction with low opacity. This case was a felis catus with a history of repeated vomiting. No obvious foreign body was found after plain X? ray，and linear intestinal foreign body was diagnosed by abdominal b ? ultrasound，and then surgical treatment was performed under the guidance of sterile urethral catheter. Postoperative b?ultrasound was used to monitor the intestinal recovery，diagnose functional obstruction caused by gastrointestinal inflammation and evaluate the intestinal healing at the operative site，providing a basis for subsequent treatment with a good prognosis.
