Triple antibiotic ophthalmic ointment, also known as neomycin and polymyxin B with bacitracin or gramicidin (brand names Neosporin Ophthalmic Ointment, Neo-Polycin Ophthalmic Ointment, Trioptic-P, Vetropolycin), is a combination antimicrobial medication used to treat certain types of bacteria (gram-positive and gram-negative). It is used to treat eye infections, eyelid infections, and infections of the tissue surrounding the eye (conjunctiva). Caution when using this medication in cats as allergic reactions have been reported.

Tropicamide is applied in the eye and is used off label to dilate the eye and to prevent and treat scarring after cataract surgery. Give as directed by your veterinarian. Common side effects include drooling, eye dryness, temporary stinging sensation upon initial application to the eye, light sensitivity, and blurry vision. Do not use in pets that are allergic to it or that have glaucoma. If a negative reaction occurs, please call your veterinary office.

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).

TTouch is a form of touch therapy devised and popularized in 1978 by Linda Tellington Jones, an equestrian with a long-standing interest in massage, training, and physical therapy techniques. TTouch is a simple, light massage technique in which the practitioner uses a clockwise circular motion of the fingers on the skin of the patient.

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.

Tularemia is an infection of the bacteria Francisella tularensis and is most common in rabbits and rodents. Infection in cats occurs from ingestion of an infected animal, drinking contaminated water, or getting bitten by a blood-sucking insect. Clinical signs include enlarged lymph nodes and draining abscesses. Treatment includes antibiotics, surgical removal of any draining abscesses, and any other supportive care warranted by the cat's condition. Tularemia is a reportable zoonotic disease.

Tylosin is an antibiotic given by mouth or by injection in small mammals and is used off label to treat diarrhea and inflammatory bowel disease. Common side effects include decreased appetite and diarrhea. Do not use in pets that are allergic to it. If a negative reaction occurs, call your veterinary office.

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.

Ultra-micronized palmitoylethanolamide (PEA-um), brand name Redonyl Ultra, is a nutraceutical used to support skin health in dogs and cats. PEA-um comes in oral chewable and powder forms. It is used "off label" or "extra label".

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. It cannot be used to identify abnormalities in areas of air such as the lungs, or areas surrounded by bone. Ultrasound-guided biopsies can be taken of abnormal areas which are sent to a pathologist for interpretation. Anesthesia is generally not needed unless tissue biopsies are planned. Shaving of fur is recommended to allow best contact of the probe with the skin to produce the most diagnostic images. 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.
