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.

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.

Botulism is a rare condition that causes paralysis in cats. Cats are exposed to botulism by eating raw meat or dead animals containing botulinum toxin produced by Clostridium botulinum.

Bowel incontinence is the loss of the ability to control bowel movements. There are two broad causes of fecal incontinence: reservoir incontinence and sphincter incontinence. In reservoir incontinence, intestinal disease interferes with the rectum's ability to store normal volumes of feces. In sphincter incontinence, a structural or neurologic lesion prevents the anal sphincter from closing normally. Clinical signs, diagnostic testing, and treatment vary based on the underlying cause.

Brachycephalic airway syndrome refers to a particular set of upper airway abnormalities that affect brachycephalic cats. The most common sign of the condition is mouth breathing and, in the long term, the increased effort associated with breathing can put a strain on the cat's heart. Surgery is the treatment of choice whenever the anatomical abnormalities interfere with a cat’s breathing.

Brain injuries are devastating and, unfortunately, often fatal. The typical signs of brain injury in a cat include altered consciousness that may signal bleeding in the skull, decreased blood flow to the brain, or fluid causing swelling within the brain itself. There are many potential causes of brain injury and treatment will always be determined by the underlying problem that led to the injury.
