Cats + Medical Conditions

  • Ataxia means incoordination within the nervous system. There are several forms of ataxia, depending upon where in the nervous system the abnormality occurs. The most common sign of ataxia is an abnormal, unsteady gait. Treatment of ataxia will be influenced by the root cause. Pain management, supportive care (such as anti-nausea medication), and creating a safe environment (e.g., preventing access to stairs) are cornerstones of ataxia treatment.

  • This handout summarizes atlantoaxial (AA) luxation, a condition in which instability or excessive movement is present between the first two vertebrae within the neck. This instability causes pressure on the spinal cord. Atlantoaxial luxation can be caused by trauma, hereditary factors, or a combination of both.

  • This handout discusses atopic dermatitis (atopy), a form of allergic skin disease brought on by an abnormal response to allergens in the environment. The clinical signs, diagnosis, and treatment are outlined.

  • Atrial fibrillation describes rapid contractions or twitching of the heart muscle, specifically in the atria. In cats, atrial fibrillation occurs secondary to heart disease. The signs that are observed are often related to that underlying condition, and may include exercise intolerance, cough, or difficulty breathing. Signs, treatment, and outlook are discussed.

  • Atrioventricular (AV) valve dysplasia is a developmental malformation of the mitral or tricuspid valve in the heart. Signs include exercise intolerance, accumulation of fluid in the abdomen, weight loss, and stunted growth. Difficulty breathing or collapse may occur if congestive heart failure develops. Treatment of AV valve dysplasia is focused on managing signs of congestive heart failure and/or disturbances in heart rhythm, generally using medications.

  • An aural hematoma is a collection of blood between the cartilage and skin of the ear flap. It is most usually caused by trauma but can also be due to a bleeding disorder. Hematomas in cats should be treated early to minimize pain and disfigurement.

  • AIHA or IMHA is a life-threatening condition that may occur as a primary condition or secondary to another disease. Most cats with AIHA have severe anemia and their gums will be very pale. They will be anorexic, listless, easily tired, and will have increased heart and respiration rates. Diagnosis involves a complete blood count (CBC), biochemical profiles, urinalysis, and X-rays or ultrasound of the abdomen and chest. Treatment may involve blood transfusions and other medications over a prolonged time. The prognosis may be better if an underlying cause can be identified.

  • Autoimmune disease causes the immune system to attack itself by mistake, causing illness. With autoimmune skin disease the immune system attacks the body's own skin tissues. Variations of autoimmune skin disease are described, along with clinical signs, diagnosis, treatment, and prognosis.

  • Bladder stones are rock-like formations of minerals that develop in the urinary bladder. All stones form because of disease or inflammation in the bladder. The most common signs in cats are bloody urine and straining to urinate. X-rays (with or without contrast dyes) or ultrasound may be necessary for diagnosis. The fastest way to remove bladder stones is via a surgical procedure called a cystotomy. Special diets or passing a catheter may be successful for some bladder stones. Your veterinarian will advise you of the best course of action for your cat's situation.

  • Blepharitis (inflammation of the eyelid) can affect one or both eyes. The affected eyelid will usually be red, swollen, and itchy. Any condition that can cause irritation of the eyelids can lead to blepharitis. The numerous potential causes of this condition, along with the clinical signs, diagnosis, treatment, and prognosis are outlined in this handout.
