Cats + Medical Conditions

  • Feline eosinophilic keratitis is a chronic, inflammatory disease of the cornea. In cats with eosinophilic keratitis, eosinophils (a type of white blood cell) invade the cornea, giving the surface of the eye a pink, white, and/or chalky appearance.

  • Epiphora means an overflow of tears from the eyes. It is a symptom rather than a specific disease and is associated with a variety of conditions. Normally, a thin film of tears is produced to lubricate the eyes and the excess fluid drains into the lacrimal or tear ducts, which are located in the medial canthus or corner of the eye next to the nose.

  • Eosinophilic granuloma complex is a term used to describe three forms of skin lesions in cats: 1) eosinophilic plaque, 2) eosinophilic granuloma and 3) indolent ulcers. These lesions have a characteristic microscopic appearance due to the presence of eosinophils, which are a form of inflammatory cell. The term is descriptive, referring to the microscopic appearance of the lesion.

  • Feline Viral Rhinotracheitis (FVR) is an infectious disease caused by feline herpesvirus type-1. As with other herpes viruses, the virus is very species specific, and is only known to cause infections in domestic and wild cats. The virus can infect cats of all ages.

  • Feline Lower Urinary Tract Disease (FLUTD) is a term used to describe a set of clinical signs associated with abnormal urination in cats. When the condition has no identifiable cause, it is called Feline Idiopathic Lower Urinary Tract Disease (iFLUTD) to indicate that this is an exclusionary diagnosis.

  • Feline miliary dermatitis is a general term used to describe a skin condition in cats that most commonly results from an allergic reaction. Since the most common allergic dermatitis or skin allergy in the cat is flea allergy dermatitis, the two terms have become synonymous. The term miliary means resembling millet seeds.

  • Feline vestibular disease is a condition in which a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth (nystagmus), a head tilt, and often nausea or vomiting. These clinical signs usually appear suddenly, many times in less than an hour.

  • Fever is a term that refers to an elevated body temperature. The normal body temperature range for cats is between 100.5°F and 102.5°F (38.1°C to 39.2°C). To be classified as a fever of unknown origin (FUO), the body temperature must be above 103.5°F (39.7°C) on at least four occasions over a fourteen-day period, accompanied by an illness of at least fourteen days' duration without an obvious cause.

  • An FCE is the acute death of part of the spinal cord, caused by the embolus of fibrocartilaginous material. The material blocks arteries and/or veins in the spinal cord and may originate in an intervertebral disk or the marrow found within a vertebral body.

  • A focal seizure refers to an abnormal surge of electrical activity that is confined to a specific area of the brain. Unlike a generalized seizure, in which the animal’s entire brain is affected and therefore the entire body shows signs of a seizure, a focal seizure only affects a localized region of the brain and therefore only has limited effects on the body.
