Cats + Medical Conditions

  • Cerebellar hypoplasia is a developmental condition in which the cerebellum of the brain fails to develop properly. The cerebellum is the portion of the brain that controls fine motor skills, balance and coordination. The condition is not painful or contagious.

  • Feline chin acne is a poorly understood disorder of follicular keratinization. Keratinization refers to the overproduction of keratin, a protein found in the outer layer of skin. If this excess keratin is trapped in the hair follicle, comedones or 'blackheads' form. Feline chin acne is similar to the acne that humans get.

  • Feline chlamydial conjunctivitis, or chlamydophila (previously known as feline pneumonitis) is an infection caused by a bacterial organism called Chlamydophila felis. Although the term pneumonitis implies inflammation of the lungs, the most common signs of infection involve the eyes or the upper respiratory tract (nose or throat), and only when infection is not treated does it spread to the lungs.

  • Cholangitis is a term referring to inflammation of the bile duct. Cholangiohepatitis means inflammation of the bile ducts, gall bladder, and surrounding liver tissue. Cholangitis and cholangiohepatitis usually occur together as a complex or syndrome (CCHC or CCHS) and is much more common in cats than in dogs.

  • The kidneys have many functions. They principally act to remove waste products from the blood stream, regulate the levels of certain essential minerals such potassium and sodium, conserve water, and produce urine. The kidneys have a large amount of spare capacity to perform their various functions so at least two-thirds (67% to 70%) of the kidneys must be dysfunctional before any clinical signs are seen.

  • Chronic Obstructive Pulmonary Disease is a long-term inflammatory condition that affects the pulmonary or respiratory system. This condition is irreversible and is slowly progressive. This condition may also be known as "chronic bronchitis".

  • When clinical signs of upper respiratory tract inflammation, such as sneezing or nasal and eye discharge, persist over weeks or months, or when they tend to recur at intervals of a few weeks, the condition is referred to as chronic upper respiratory tract disease. A runny or stuffed-up nose is the most common clinical sign in cats with chronic infections. There are many causes of this relatively common problem in cats. The treatment will be determined by the test results and diagnosis.

  • Chylothorax is a relatively rare condition in cats in which lymphatic fluid or chyle accumulates in the pleural cavity. Normally, only about a teaspoon (5 milliliters) of clear fluid is present in this space. When chylothorax is present, up to a quart (liter) of fluid may be present in this space. In some cases, chylothorax may be caused by trauma or by increased pressure within the thoracic duct or vena cava. Trauma may cause the thoracic duct to rupture or become 'leaky.'

  • The general condition of your cat's skin and coat are good indicators of its health. A healthy coat should be shiny and smooth, not coarse or brittle, and healthy skin should be supple and clear, not greasy, flaky or bumpy.

  • Coccidioidomycosis is a fungal disease caused by the soil fungus Coccidioides immitis. The early signs of coccidioidomycosis include fever, lethargy, poor appetite, coughing, and joint pain.
