Acute respiratory distress syndrome (ARDS), also known as shock lung, is a life-threatening complication of critical illness in cats, such as systemic infection, systemic disease, severe trauma, or near-drowning. Treatment involves targeting the underlying cause while supporting the cat's compromised lung function.

Addison’s disease, also known as hypoadrenocorticism, is a condition in which the adrenal glands do not produce enough glucocorticoids (steroids) and is considered rare in cats. When normal adrenal gland tissue is destroyed, cats often have a history of waxing and waning periods of lethargy, decreased appetite, and weight loss.

Anticoagulant rodenticide is used to kill mice, rats, and other rodents. Poisoning occurs when a cat ingests rodenticide. Anticoagulant rodenticides cause excessive bleeding by interfering with vitamin K1 recycling in the body. Vitamin K1 is needed for the body to make certain clotting factors that enable blood to clot and help to control bleeding.

Aortic stenosis is a heart disease that is present at birth. Cats affected with aortic stenosis have a narrowing at the aortic valve of the heart. The clinical signs of aortic stenosis vary depending on how severe the stenosis is; some cats remain asymptomatic throughout their life, while other cats begin showing clinical signs at an early age and can experience sudden death. The treatment of aortic stenosis depends upon the severity of the condition.

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.

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.

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.

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.
