  • 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.

  • Constipation is defined as an abnormal accumulation of feces in the colon resulting in difficult bowel movements. Constipation is a condition seen most commonly in mature, middle-aged cats and can be caused by hairballs, ingestion of foreign bodies, pelvic injuries, or obesity and/or lack of exercise. Megacolon is the most common cause of constipation in cats. In most cases, a diagnosis of constipation can be made on the basis of the cat's clinical signs and medical history. Treatment varies depending on the cause of constipation. The long-term outlook varies according to the cause of the constipation; however, most cats can be adequately managed without surgery and resume normal, healthy lives.

  • This handout outlines corneal ulcers in cats, a painful eye condition often resulting from trauma. Other causes, clinical signs, diagnostic testing, and treatment options are also explained.

  • A cough is an expiratory effort producing a sudden, noisy expulsion of air from the lungs. In cats, coughing is most often a sign of an inflammatory problem, affecting the lower respiratory tract, especially some form of bronchitis, often due to an infection. Heartworm infection, allergies, presence of foreign material within the airway, or irritation from inhaled liquids or gases can all be responsible for coughing and respiratory problems in cats. In order to diagnosis the cause, blood tests, laboratory cultures, endoscopic examination, and radiography may be performed. Treatment depends on the diagnosis and your cat's medical condition.

  • This handout outlines cruciate ligament rupture, an orthopedic condition, in cats. The common causes, clinical signs, diagnosis, and treatments are described.

  • Skin cancers are common in cats, but cutaneous lymphoma is relatively uncommon. Less than 2% of lymphoma cases in cats occur in the skin. As the disease progresses, the skin becomes thickened, reddened, ulcerated, and may ooze fluid. The most common locations to find lesions include the junction between mucus membranes and the skin. Unfortunately, feline cutaneous lymphoma is considered incurable. Surgical removal can be attempted for solitary lesions, although the tumor often returns to the area or will have spread elsewhere in the body already

  • Cuterebra is the scientific name for the North American rabbit or rodent botfly. Cats are accidental hosts of Cuterebra larvae, and they are rarely evident from external skin inspection. A hole enlarges when the warble has matured, often leading to an infected empty cyst. Treatment depends on when the condition is discovered, and in many cases, antibiotics are used to treat secondary infections.

  • In cats, diseases of the lower urinary tract (bladder and urethra) are often grouped under the term feline lower urinary tract disease (FLUTD). Typical signs in cats with FLUTD are those of inflammation and irritation of the lower urinary tract. There are many potential causes of FLUTD, and diagnosis is based on assessing clinical signs and laboratory testing. There is no universal treatment for FLUTD. Each case has to be investigated to determine the underlying cause, and then the treatment has to be tailored to the individual cat.

  • Cysts are hollow spaces within tissues that contain either a liquid or a solidified material. Some breeds have a tendency to develop certain types of cysts. Accurate diagnosis relies upon microscopic examination of a piece of tissue. The most common treatment for cysts is surgical removal. It is important to prevent your pet from rubbing, scratching, or otherwise bothering the cysts or the surgical site.

  • Cytauxzoonosis is an often-fatal disease caused by a tick-borne protozoan parasite, typically found in bobcats. It is more commonly seen in the southern United States but is spreading with tick migration. It can cause anorexia, lethargy, respiratory difficulty, anemia, and jaundice. Diagnostic testing, treatment options, and preventives are described in this handout. This disease is not transmissible to dogs or humans.
