The anal sacs are two small pouches located on either side of the anus. The walls of the sac produce a foul-smelling fluid that is released when a cat passes a bowel movement. The anal sacs or their ducts can become inflamed or infected due to a variety of causes. Most cats will respond well to pain relief medications and antibiotics. If a cat has several episodes of anal sac disease, and dietary changes and supplements or medication do not relieve the problem, the anal sacs can be removed surgically.

The word anesthesia comes from the Greek meaning "lack of sensation". Anesthesia is accomplished by administering drugs that depress nerve function. With general anesthesia, the patient is made unconscious for a short period. During this unconscious state, there is muscular relaxation and a complete loss of pain sensation.

This handout discusses arthroscopy, the insertion of a telescope-like camera into a joint. The joints commonly examined and treated using this technique, along with the benefits and risks of this procedure, are outlined.

Bandages and splints protect an injured or wounded area of the body. It is important to closely monitor your cat's bandage or splint to ensure it does not slip or become wet or soiled and to ensure there is no discharge or foul odors indicating infection. This handout explains optimal bandage and splint care for your cat at home as well as possible complications that will require veterinary attention.

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.

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.

Calcium oxalate bladder stones are composed of a mineral called calcium oxalate. Cats are more likely to develop oxalate stones when their urine contains high levels of calcium and oxalate. Additionally, a low urine pH promotes the formation of oxalate stones. Bladder stones can cause significant inflammation and irritation of the bladder wall. Signs may include frequent urination, straining to urinate, blood in the urine, and urinating outside of the litterbox. Male cats especially are at risk of a life-threatening urinary obstruction. Treatment options and prognosis are discussed.
