  • 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.

  • Chlamydiosis (psittacosis, parrot fever, ornithosis) is a common disease of birds caused by a bacterial organism. The disease can cause chronic infections, infections without visible symptoms, or sudden death. The disease can also be transmitted to people, but it is not associated with the venereal form of chlamydia.

  • 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 bronchitis (also known as chronic obstructive pulmonary disease or COPD) is a long-term inflammatory condition that affects the pulmonary or respiratory system. The most common sign is a chronic dry cough. This condition is irreversible and is slowly progressive. The diagnosis, treatment, and prognosis are outlined in this handout.

  • This handout summarizes the normal function of the dog heart and outlines the abnormalities and changes associated with degeneration of the four different valves in the heart. Clinical signs associated with valve disease are summarized, as well as the recommended tests and treatments for this condition.

  • Chronic egg laying occurs when a female bird lays more eggs in one clutch than the usual number or lays repeated clutches of eggs. Chronic egg laying may lead to malnutrition and egg binding. There are behavioral and medical interventions to stop chronic egg laying.

  • Chronic hepatitis is a progressive inflammatory liver condition. Although there are many potential causes, often the underlying cause is not identified. Initially there may be no clinical signs but as liver scarring increases, signs can include decreased appetite, vomiting, diarrhea, abnormal bleeding and a bloated appearance. Diagnosis, treatment and prognosis are discussed.

  • 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 kidney disease (CKD) is the inability of the kidneys to efficiently filter the blood of waste products. In dogs, chronic kidney disease is associated with aging. For most small dogs, the early signs of kidney disease occur around 10 to 14 years of age, while it may occur in large dogs as early as seven years of age. This handout describes clinical signs, causes, diagnosis, treatment, and nutritional management.
