Cats + Medical Conditions

  • Chin acne in cats is a poorly understood disorder of follicular keratinization (the overproduction of keratin, a protein found in the outer layer of skin). This handout outlines potential causes, clinical signs, treatment, and prognosis of this condition.

  • Chlamydial conjunctivitis in cats is highly contagious and can look similar to herpes conjunctivitis. Young cats and kittens are especially vulnerable to this infection, although chlamydia can be detected in cats of all ages. It is one of the most common causes of infectious conjunctivitis in cats. This handout describes the clinical signs and how this condition can be treated or prevented.

  • Cholangitis/cholangiohepatitis syndrome (CCHS) is an inflammatory liver disease. Cholangitis is inflammation of the bile ducts. Cholangiohepatitis is inflammation of the bile ducts, gallbladder, and surrounding liver tissue. This handout outlines clinical signs, diagnosis, treatment, and prognosis.

  • Chronic bronchitis is a long-term inflammatory condition that affects the pulmonary or respiratory system. This condition is irreversible and is slowly progressive. This article discusses how the condition is diagnosed as well as treatments to slow the progression of the disease.

  • Chronic kidney disease (CKD) is the inability of the kidneys to efficiently filter the blood of waste products. It is mainly a problem in mature and senior cats (seven years and older), affecting 30% to 40% of cats over 10 years of age and 81% of cats over 15 years. This handout describes clinical signs, causes, diagnosis, treatment, and nutritional management.

  • Chronic upper respiratory tract disease in cats results from long-term inflammation of any part of the upper respiratory tract. It can occur for a variety of reasons. Common signs include sneezing, nasal or eye discharge, and noisy breathing. It is often associated with chronic viral infections and secondary bacterial infections.

  • Chylothorax is a relatively rare condition in cats in which lymphatic fluid (called chyle) leaks into the pleural cavity (an area between the lungs and the inner lining of the chest wall), 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.

  • Coccidioidomycosis is a fungal disease caused by the soil fungus Coccidioides immitis or Coccidioides posadii. The early signs of coccidioidomycosis include fever, lethargy, poor appetite, coughing, and joint pain. Diagnosis is by biopsy of lesions or blood testing for antibodies to the Coccidioides organism. The prognosis for recovery is dependent of the extent of lesions in the cat’s body.

  • Severe heart disease in cats can lead to congestive heart failure, a condition that occurs when the heart is no longer able to pump blood to the body, and fluid starts to back up. With right-sided heart failure, fluid backs up in body cavities, whereas with left-sided heart failure, fluid backs up into the lungs. The most common type of heart disease in cats is hypertrophic cardiomyopathy (HCM). Difficulty breathing is the number one clinical sign.

  • 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.
