  • Chronic kidney disease (once called chronic kidney failure) is mainly a problem in mature and senior cats (seven years and older). Unfortunately, once the kidneys are damaged, they have minimal ability to recover. However, with proper management, most CKD cases progress very slowly. This handout describes the clinical signs of the condition, along with causes, diagnosis, treatment, and nutritional management.

  • Chronic upper respiratory tract disease in cats results from inflammation of any part of the upper respiratory tract. Many conditions contribute to this. Treatment is based on the underlying cause.

  • Chylothorax is a life-threatening condition caused by chyle leaking out of the thoracic duct into the chest cavity, causing lung compression and the inability of the lungs to fill with air. This occurs more commonly in purebred cats. The causes, diagnostics, treatments, and prognosis are explained in this handout.

  • Cidofovir ophthalmic is a topical antiviral medication used to treat viral eye infections, such as feline herpesvirus-1, in cats. This medication must be compounded by a veterinarian or veterinary pharmacy before use in cats. Side effects may include a mild stinging sensation or redness of the eyes. Pregnant women should not handle this medication.

  • Coagulation is the series of events that result in the formation of a clot. In the body, coagulation occurs after any injury to a blood vessel or tissue, in order to stop bleeding. Some breeds of dogs are known to have a higher incidence of clotting factor deficiencies and with these breeds, coagulation tests may be used for screening purposes prior to diagnostic or surgical procedures.

  • Your cat's skin and coat condition 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 various coat characteristics requiring varying grooming needs. To maintain healthy skin and coat, your cat also requires a properly balanced diet.

  • Coccidia are single-celled organisms that can act as a parasite after infecting your cat through the gastrointestinal tract. The most common form affecting cats, Isospora, is not a concern for infecting people, unlike Toxoplasma. They are highly resistant to environmental conditions, so cleanliness is important to prevent re-infection. Treatment is often simple with the appropriate antibiotics prescribed by your veterinarian.

  • The complete blood count (CBC) assesses different parameters of the cells in the blood including total number, appearance, size, and shape. Red blood cells, white blood cells, and platelets comprise the cellular component of the blood. Changes in the red blood cells can affect oxygen delivery from the lungs to the blood. Changes in the white blood cells can indicate infection, inflammation, and cancer. Platelets are needed for adequate blood clotting so decreased numbers can raise concern for spontaneous bleeding.

  • Conjunctivitis means inflammation of the conjunctiva. If you see excessive tearing from one or both eyes, abnormal discharge, and reddened conjunctival membranes, your cat may have conjunctivitis. The most common causes of conjunctivitis include infectious diseases and non-infectious conditions, including allergies, injuries, hereditary conditions, and tumors. The approach to non-specific conjunctivitis is to use eye medications containing a combination of broad-spectrum antibiotics to control the bacterial infection and anti-inflammatory drugs to reduce the inflammation. The prognosis depends on the specific diagnosis. It can be a recurring condition in some cats.

  • Constipation is defined as an abnormal accumulation of feces in the colon resulting in difficult bowel movements. Constipation is a condition seen most commonly in mature, middle-aged cats and can be caused by hairballs, ingestion of foreign bodies, pelvic injuries, or obesity and/or lack of exercise. Megacolon is the most common cause of constipation in cats. In most cases, a diagnosis of constipation can be made on the basis of the cat's clinical signs and medical history. Treatment varies depending on the cause of constipation. The long-term outlook varies according to the cause of the constipation; however, most cats can be adequately managed without surgery and resume normal, healthy lives.
