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.

These two conditions are the result of calcium being deposited within the skin. They are usually of minor significance in young dogs and cats but can indicate serious underlying diseases in older pets. This handout describes the different types of calcinosis circumscripta and cutis and associated causes, clinical signs, and treatments.

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.

Cardiomyopathy is a term used to describe diseases of the heart muscle. In cats, three classes of cardiomyopathy have been described: hypertrophic, dilated, and intermediate or restrictive cardiomyopathy. In the early stages of disease, the cat may not show any signs. Heart disease can be suspected based on clinical signs, chest X-rays, and electrocardiography (ECG). The long-term prognosis for a cat with cardiomyopathy is variable, and depends on the cause of disease.

Carpal hyperextension is an abnormality of the carpus (wrist) that causes increased extension of the joint. Carpal hyperextension in cats is typically caused by trauma. Cats can also develop carpal hyperextension in association with other systemic diseases (e.g., inflammatory arthritis, diabetes mellitus, electrolyte abnormalities). Cats with carpal hyperextension have a noticeable bend at the wrist, forcing their foot into an abnormally flattened position. If carpal hyperextension is caused by trauma, it may also be associated with pain and swelling. A tentative diagnosis of carpal hyperextension can be made based on initial observation, but a thorough physical examination is necessary because cats with carpal hyperextension may also have abnormalities in other joints. X-rays and other additional tests may be recommended. Treatment of carpal hyperextension depends upon the severity of the condition and may involve surgery.
-
Carpal laxity is a condition in which the carpus has an abnormal or excessive range of motion. Carpal laxity can show up in one of two ways: carpal hyperextension or carpal flexion. The underlying cause of carpal laxity has not been definitively determined but may be caused by nutritional factors, genetic factors, and being raised on slippery flooring surfaces. Signs of carpal laxity may be seen at any time from 6 weeks of age onward, but the condition is most commonly noted between three and six months of age. Activity modification is often recommended for affected kittens by keeping them off slippery surfaces. Most kittens with carpal laxity will appear completely normal within six to eight weeks.

House soiling in cats, also called feline inappropriate elimination, is the most common behavioral complaint of cat owners. Problem behaviors can be urine and/or stool deposited outside of the litter box, or marking behaviors.

A cataract is an increase in opacity of the eye’s lens. Any type of inflammation or damage to the lens can lead to a cataract. The clinical signs of cataracts vary depending on the size of the cataract; many cataracts are asymptomatic at the time they are diagnosed during a veterinary exam. The ideal treatment for cataracts is surgery, but not all cats are candidates for surgical treatment. In these cases, anti-inflammatory medications may be used to prevent glaucoma and other secondary complications of cataracts.
