Trypsin-like immunoreactivity (TLI) is a blood test that measures the amount of a pancreatic proenzyme called trypsinogen. This measurement correlates with the amount of pancreatic enzymes released into the intestine to aid in digestion. A low measurement indicates exocrine pancreatic insufficiency. Concurrent pancreatitis or tests done shortly after a meal may temporarily increase this measurement to a normal value (false negative).

Tube feeding is important to maintain adequate nutrition and prevent liver problems in cats that are anorexic for at least 2 days. Tube feeding may be needed because of a mechanical problem interfering with ingestion of food or because of a systemic illness that is causing the cat to be anorexic. There are several different options for tube feeding. Naso-esophageal/naso-gastric intubation passes a tube down the nose into the esophagus and sometimes into the stomach. This is only suitable for short term feeding. Placement of an esophageal tube requires sedation or anesthesia as a hole is made through the skin and esophagus to pass the tube through into the esophagus. An esophageal tube can be maintained for weeks to months. A gastrostomy tube requires anesthesia to pass a tube through the skin directly into the stomach. This is beneficial for longer term feeding. A tube must be protected to prevent the cat from pulling it out. The recommended diet is administered in liquid form by a syringe several times a day. Complications are rare with clogging and inadvertent removal most common.

Damage to the tympanic membrane and middle ear infections can be very painful for cats and cause a variety of clinical signs affecting the skin and nervous system. Diagnosis often requires a thorough ear examination with testing while your cat is under sedation or anesthesia. The treatment methods and prognosis depend on the nature of your cat's condition.

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.

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.

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.

Uterine tumors are quite rare in North American pets, mainly due to routine spaying practices. Several types of tumors can arise from the tissues of the uterus. This handout discusses uterine tumors in dogs and cats. The various types of these tumors, along with the clinical signs, diagnosis, treatment, and prevention of this condition are outlined.

There are five primary reasons for vaccination failure. Vaccine inactivation is one reason and is most commonly caused by warming during shipping and handling. In addition, vaccines are not always 100% effective. Cats may also be unhealthy or too young, leading to vaccine failure. Interference by maternal antibodies can lead to the vaccine being blocked. Lastly, cats receiving overwhelming exposure to a virus may have a failure in the effectiveness of the vaccine.

Vascular tumors of the skin develop from the blood vessels of the skin. These tumors may arise anywhere on the body and appear as a firm and raised lump on or under the skin. Hemangiomas may ulcerate and bleed; hemangiosarcomas may bleed into the surrounding tissues. This type of tumor is typically diagnosed via a tissue biopsy or surgical removal of the entire tumor. Surgery is the recommended treatment for vascular tumors of the skin.

Vestibular disease is when a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth, a head tilt, and often nausea or vomiting. Most cases are idiopathic, meaning the exact cause is unknown. Idiopathic vestibular disease is a short-term, self-resolving condition with a good prognosis.
