Chediak-Higashi Syndrome is a rare genetic disease of smoke-blue Persian cats. The condition affects how the body processes waste products, resulting in changes within the body’s cells and leading to abnormal pigmentation of the skin and coat. The condition can lead to eye abnormalities and problems with blood clotting, but most cats can have a normal lifespan with careful health monitoring.

A chemodectoma is a type of tumor made up of chemoreceptor cells. Chemoreceptor cells detect chemical changes in the body and respond by regulating chemical or physical processes. These tumors are most often seen along one of the carotid arteries and the aorta. Brachycephalic breeds are more predisposed to these types of tumors, though they may occur in any dog breed. These tumors are usually locally aggressive, however, there are rare cases of metastasis to other organs, including the lungs, lymph nodes, and bone.

Chemotherapy drugs are used to treat cancer and other conditions in people because they target and kill rapidly dividing neoplastic (cancer) cells and other cells. They are primarily used as anti-cancer agents but may also provide benefits for a variety of auto-immune disorders and organ transplant recipients as immunosuppressive agents.

Cherry eye is a common name for a prolapsed third eyelid gland. The gland is mainly responsible for tear production in the eye, and treatment is recommended to prevent long-term damage. Treatment involves surgical replacement of the gland, though some dogs will have a recurrence of the problem.

Cheyletiellosis is an uncommon but highly contagious skin parasite of dogs, cats, humans, and rabbits caused by Cheyletiella spp. mites. The most important clinical sign of cheyletiellosis is scaling or dandruff. Due to the large size of the skin mite, it is easily seen under a microscope set on low magnification. Cheyletiella mites are susceptible to most topical insecticides and the prognosis is excellent.

The birth of a baby or the adoption of a new child can be associated with both excitement and stress. It is important to prepare your pet for the new addition. Before the baby arrives, introduce novel sounds and scents, and be sure your pet has access to safe resting spaces. Socialize your young pet to children from the start. Children should be directly supervised by an adult when they interact with pets.

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). If this excess keratin is trapped in the hair follicle, comedones (blackheads) form. Pustules (pimples) may form if bacteria infect the comedones. The underlying causes are not fully understood but may be associated with excess sebum production, viral infection, immunosuppression, stress, or poor grooming. Treatment options are available and often involve improved hygiene.

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.

Choke is a relatively common condition that occurs when food or a foreign body blocks the horse's esophagus (gullet), which is the tube that takes food from the back of the mouth (pharynx) to the stomach.

Cholangitis/cholangiohepatitis in cats refers to inflammation of the bile duct or a combination of inflammation of the bile duct, gallbladder, and surrounding liver tissue. The clinical signs, diagnosis, treatments, and prognosis of the conditions are outlined in this handout.
