Cerebellar hypoplasia is a developmental condition in which the cerebellum of the brain fails to develop properly. It most commonly occurs when a pregnant cat becomes infected with feline panleukopenia virus and passes the infection to her unborn kittens. There is no treatment, but kittens with cerebellar hypoplasia are not infectious to other kittens or cats, are not in any pain, and will learn to adapt to their disability over time.

The intervertebral discs allow movement in the spine and act as shock absorbers between the vertebrae. If the disc degenerates or is damaged in some way, the disc may bulge and put pressure on the spinal cord and/or the roots of the spinal nerves that come off the sides of the spinal cord. This pressure can cause symptoms ranging from severe pain to weakness to paralysis.

Cervical vertebral instability (wobbler syndrome) is caused by compression of the spinal cord, usually at the base of the neck. Although the spinal cord compression occurs in the neck, the hind legs are often affected first. In severe cases, the dog may suddenly develop total paralysis of all four limbs. The condition is most prevalent in Great Danes and Doberman Pinschers. Most pets enjoy a relatively normal lifestyle following surgery.

Chediak-Higashi Syndrome is a rare genetic disease that affects 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.

Cherry eye is a common name for a prolapsed (popping out) third eyelid gland. The gland is responsible for most tear production in the eye, and treatment is recommended to prevent long-term damage, although some dogs will have a recurrence of the problem. An artificial tears ointment can help keep the eye lubricated until surgery is performed.

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.
