Cats + Medical Conditions

  • Feline viral rhinotracheitis (FVR) is an infectious disease caused by feline herpesvirus type-1. It is a major cause of upper respiratory disease in cats, and is the most common cause of conjunctivitis. The typical symptoms of FVR involve the nose, throat, and eyes, and include sneezing, nasal congestion, conjunctivitis, excessive blinking, squinting, and discharges from the eyes and nose that range from clear and watery to thick and purulent (containing yellow/green pus). Treatment consists of supportive care, hydration of the environment, and control of secondary bacterial infections with antibiotics and antibiotic eye medications. An effective vaccine exists and is recommended for all cats.

  • Histoplasmosis is a chronic, non-contagious fungal infection caused by the soil-dwelling fungus Histoplasma capsulatum. Histoplasma capsulatum is found globally and may infect both humans and animals. However, histoplasmosis is uncommon to rare in all but dogs and cats.

  • Horner's Syndrome is a common neurological disorder of the eye and facial muscles, caused by dysfunction of the sympathetic nervous system.

  • Hypertension is the medical term for high blood pressure. A cat is generally thought to be hypertensive when its systolic blood pressure is above 175 mm Hg.

  • Cats have two thyroid glands, which are located in the neck and play a vital role in regulating the body's metabolic rate. Hyperthyroidism is characterized by the overproduction of thyroid hormone and a subsequent increase in metabolic rate. This disease is common in older cats.

  • Hypocalcemia means that the level of calcium in the bloodstream is low. Calcium is an important electrolyte within the body, and is needed for normal function of muscles and nerves. Calcium concentrations in the blood are usually regulated very closely but occasionally the control mechanism is impaired and may result in low blood calcium concentrations.

  • Hypokalemia is a term that refers to a low blood concentration of potassium. Potassium is an important electrolyte within the body and is vital for the normal function of muscles and nerves. In some situations, the normal control of body potassium concentration is lost, resulting in depletion of potassium and low blood potassium concentrations.

  • Ibuprofen is a commonly used NSAID and is used to treat fever, pain, and inflammation in humans. Ibuprofen poisoning occurs when a cat ingests a toxic dose of ibuprofen, either through misuse or by accident. Ibuprofen poisoning causes many different clinical signs because many different organ systems can be affected. Most commonly, cats show signs related to kidney problems.

  • Icterus is also known as jaundice or yellow jaundice. It refers to an excessive accumulation of a yellow pigment in the blood and tissues. When icterus has been present for any length of time, it will discolor many tissues and will become visible as jaundice on most body surfaces, including the skin.

  • There are many possible causes of infertility in female cats, including behavioral, physical, and medical factors. Your veterinarian will perform a thorough examination and testing to diagnose the reason for your female cat's infertility, and treatment will depend on the underlying cause.
