Ultrasound is a painless and non-invasive procedure that allows veterinarians to see inside the body of a cat. Through ultrasound, we can examine all major organ systems including the abdominal, heart, eyes, reproductive system, and many more. Ultrasound is extremely useful in examining the stomach and intestines for abdominal disorders. With ultrasound we can also see changes in shape, size, tissue density, and internal structure and position of organs. It may allow the examiner to find the cause behind unexplained vomiting, diarrhea, urination problems, loss of appetite, weight loss, and fever. For female cats, ultrasound can help identify reproduction abnormalities, and the number of kittens inside the womb for pregnant patients. In the case of suspected cancer, ultrasound can assist in locating masses and tumors.
