Medical Conditions

  • Chediak-Higashi syndrome is a rare genetic disease of smoke-blue Persian cats. This condition affects how the body's cells process waste, leading to changes within the cells and abnormal pigmentation of the skin and coat. Cats with Chediak-Higashi syndrome also tend to have eye abnormalities. The most significant effect of Chediak-Higashi syndrome in cats is increased bleeding, caused by abnormal platelet function, though some cats may also show signs of a weakened immune system. Most cats with Chediak-Higashi syndrome do not require treatment for this condition.

  • "Cherry eye" is a common term for prolapse of the third eyelid gland. Many mammals, including dogs, have an "extra" or third eyelid located inside the lower eyelid. This serves as an additional protective layer for the eye, especially during hunting or fighting.

  • Feline chin acne is a poorly understood disorder of follicular keratinization. Keratinization refers to the overproduction of keratin, a protein found in the outer layer of skin. If this excess keratin is trapped in the hair follicle, comedones or 'blackheads' form. Feline chin acne is similar to the acne that humans get.

  • Generally speaking, chinchillas are fairly hardy animals. However, they do have several unique problems, and understanding these problems will allow you to better care for your pet and minimize future health care problems. These include fur slip, antibiotic sensitivity, teeth problems, heat stroke, skin problems, and dust bathing for normal grooming.

  • Common conditions of pet chinchillas include bite wounds, respiratory diseases, overgrown and impacted teeth, gastrointestinal stasis, bloat, diarrhea, skin problems, and heat stroke. Any deviation of your chinchilla's behavior from normal should be a cause for concern and requires immediate evaluation by your veterinarian.

  • Chlamydial conjunctivitis in cats is an infection caused by a bacterial organism. The most common signs of chlamydia in cats involve the eyes or the upper respiratory tract (nose or throat), and only when infection is not treated does it spread to the lungs. In cats with conjunctivitis, the conjunctiva becomes swollen and red. Chlamydia is spread by close or direct contact with an infected cat, so all cats in the home can become infected. Chlamydia can be successfully treated with a course of oral and topical antibiotics.

  • Chlamydophilosis, also called "psittacosis", chlamydiosis or "Parrot Fever", is a reasonably common disease of birds. It can occur in any bird but is especially common in cockatiels, Amazon parrots and budgerigars (often referred to incorrectly as parakeets.)

  • Cholangitis is a term referring to inflammation of the bile duct. Cholangiohepatitis means inflammation of the bile ducts, gall bladder, and surrounding liver tissue. Cholangitis and cholangiohepatitis usually occur together as a complex or syndrome (CCHC or CCHS) and is much more common in cats than in dogs.

  • Chronic degenerative valve disease (CVD) is a consequence of degeneration of the valves between the atrium and ventricle on both the right and left side of the heart. The changes in the valves stops them from forming a tight seal between the atrium and ventricle when the heart is squeezing or pumping. This causes the valves to leak blood backwards into the upper chambers, and an abnormal sound called a heart murmur.

  • Chronic egg laying occurs when a female bird lays more than the normal number of eggs or, more commonly, lays repeated clutches of eggs, especially in the absence of a mate. The persistent laying of eggs may lead to malnutrition induced by the chronic depletion of calcium from the body for the production of the egg shells.
