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 her health. A healthy coat should be shiny and smooth, not brittle or coarse, and healthy skin should be supple and clear, not greasy, flaky, or bumpy. Selective breeding has led to the development of cats with a myriad of different coat characteristics requiring varying grooming needs. In order to maintain the skin and hair in a healthy state, your cat also requires a properly balanced diet.
Conjunctivitis means inflammation of the conjunctiva. If you see excessive tearing or watering from one or both eyes, abnormal discharge, or reddened conjunctival membranes, your cat may have conjunctivitis. The most common causes of conjunctivitis can be roughly divided into two categories: infectious diseases and non-infectious conditions including allergies, hereditary conditions, and tumors. Conjunctivitis may also be a secondary symptom of another eye disease. Specific tests will be performed, based on the medical history and results of an eye examination and surrounding tissues. The general approach to non-specific conjunctivitis is to use ophthalmic preparations containing a combination of broad-spectrum antibiotics to control the secondary bacterial infection and anti-inflammatory drugs to reduce the inflammation. The prognosis depends on the specific diagnosis.
Corneal lipidosis is an accumulation of fatty substances within the cornea. This is caused by genetics (corneal dystrophy), eye inflammation (corneal degeneration), or by an increase in circulating lipids in the body (hyperlipidemia). Visually, lipidosis appears as a sparkly or shiny area of the cornea. It is diagnosed by a thorough eye exam, bloodwork, and patient history. Treatment and prognosis will depend on the cause and may include treatment of underlying inflammatory conditions of the eye, or systemic treatment of elevated lipid blood levels.
The cornea is the clear, glistening membrane that makes up the surface of the eyeball. A penetration or erosion through a few layers of the outermost corneal epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is a deeper erosion through the entire epithelium down into the stroma.
SARS-CoV-2 is a new type of coronavirus that has not previously been identified. This virus is not the same coronavirus that can cause the common cold in humans, nor is it the same as canine coronavirus (CCoV). At this time, there is no evidence that any animal or pet can infect humans with the new coronavirus. Because this is a new virus and information is still being collected, as a precaution, restrict contact with your pets if you are diagnosed with COVID-19. Currently, a vaccine for this new SARS-CoV-2 coronavirus is not available.
