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.

A gastrostomy (G-) tube is a small rubber or silicone tube that passes directly into the stomach through the cat’s skin and abdominal wall. It allows you to deliver food, water, and medications directly into the stomach. This article outlines how to use and maintain a G-tube for your cat.

Severe heart disease in cats can lead to congestive heart failure, a condition that occurs when the heart is no longer able to pump blood to the body, and fluid starts to back up. With right-sided heart failure, fluid backs up in body cavities, whereas with left-sided heart failure, fluid backs up into the lungs. The most common type of heart disease in cats is hypertrophic cardiomyopathy (HCM). Difficulty breathing is the number one clinical sign.

Gastrointestinal endoscopy uses a flexible tube with a camera or viewing port to inspect the esophagus, stomach, and first part of the small intestine, or the colon. The endoscope cannot reach all areas of the small intestine, so other tests may be needed to diagnose disease in these areas. 12–18 hours fasting and enemas are required prior to endoscopy depending on the area being studied.

Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.

Ultrasound uses the reflection of sound waves to generate an image of internal structures, allowing for identification of masses, pregnancy diagnosis, abnormal heart function and muscle size, abnormalities of the orbit, and abnormal appearance of abdominal organs. Ultrasound results can be analyzed in real time; however, assessment by a radiologist may take several days. Ultrasound is an invaluable tool to detect problems in a non-invasive fashion.

Fever of unknown origin is a term used for persistent fever in pets. It has many possible causes, including infection, immune-mediated disease, and cancer. Initial steps in diagnosis are history and physical exam, followed by standard screening tests, including a complete blood count, biochemistry profile, and urinalysis. Further testing may be indicated. This article outlines the typical tests.

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.

An electrocardiogram, or ECG, is a test that is used to assess the heart. More specifically, an ECG records the transmission of an electrical impulse through the heart. This test is not painful and is typically performed as an outpatient procedure. Analyzing the electrical impulses produced as the heart beats can help identify a number of different abnormalities within the heart.

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.
