Ultrasound uses the reflection of sound waves to generate an image of internal structures, allowing for identification of masses, pregnancy diagnosis, abnormal heart function and muscle size, abnormalities of the orbit, and abnormal appearance of abdominal organs. Ultrasound results can be analyzed in real time; however, assessment by a radiologist may take several days. Ultrasound is an invaluable tool to detect problems in a non-invasive fashion.

An umbilical hernia is a protrusion of the abdominal lining, abdominal fat, or a portion of abdominal organ(s) through the area around the umbilicus. An umbilical hernia can vary in size from less than a ¼” (1cm) to more than 1” (2.5cm) in diameter. Small (less than ¼” or 1cm) hernias may close spontaneously (without treatment) by age 3 to 4 months. If the hernia has not closed by the time of spaying or neutering, surgical repair of the hernia is recommended and prognosis is excellent.

Controlled substances are medications or illicit drugs that affect the central nervous system and have the potential for abuse or dependence, both in humans and in animals. These drugs are often needed to manage pain and other conditions in pets and are relatively safe when used appropriately and under the guidance of a veterinarian. Be sure you understand the risks and responsibilities associated with controlled substance use.

Cats exhibit a wide range of behaviors that are quite normal yet may be considered undesirable by the people with whom they share their homes. Most of these behaviors develop to satisfy an innate need. Rather than trying to stop your cat from engaging in instinctual and naturally rewarding behaviors, it is essential to provide your cat with substitute behaviors and outlets that satisfy your cat’s needs.

Urinalysis is an important part of any comprehensive workup or health screen. It provides information on the urinary system including the kidneys and bladder and also can support diagnosis of metabolic disease, such as diabetes mellitus.

While urinary tract disorders are common in cats, urinary tract infections (UTIs) are fairly uncommon. Cats with UTIs tend to have the following signs: frequently passing small amounts of urine, straining to urinate, blood in the urine, crying out or whining while urinating, licking their genitals, and urinating outside the litterbox. Generally, a UTI occurs when bacteria travel up the urethra and into the bladder. If your cat presents to your veterinarian with urinary signs, your veterinarian will first perform a urinalysis. Once the culture and sensitivity results are received, an appropriate antibiotic will be prescribed. Older female cats and cats with certain health conditions may be predisposed.

Tumors of the urinary tract may present anywhere from the kidneys to the tip of the urethra. Tumors of the bladder are most common in the dog whereas tumors involving the kidneys are more prevalent in cats. Unfortunately, many tumors of the urinary tract are malignant and treatment options may be limited. Surgery is possible in select cases. Medical treatment may be beneficial in cases where surgery is not possible.

Cortisol is a stress hormone that is excreted from the body in the urine. Creatinine is a product of muscle metabolism and is normally lost in the urine at a relatively steady rate. The ratio of creatinine to cortisol in the urine can be used to account for the effect of urine concentration on cortisol measurements. Urine cortisol/creatinine ratio is usually evaluated in animals suspected of having Cushing's disease. This test involves the collection of a single urine sample, taken first thing in the morning.

The presence of protein in urine is called proteinuria, and it may indicate that the kidneys are not working properly. In some situations, proteinuria may even be a sign of kidney failure; however, bleeding or inflammation in the urinary system is a far more common cause. Your veterinarian may recommend further testing if the urinalysis reveals inflammation or bleeding.

The urine protein/creatinine (UPC) ratio is a test that measures how much protein is being lost through the kidneys. The UPC measures whether protein excretion is greater than expected when compared to the excretion of creatinine. Before the UPC ratio can be interpreted, two other measures of kidney function should be taken: blood urea nitrogen (BUN) and serum creatinine.
