Feline Obesity Study Guide

Feline obesity is defined as a body weight greater than 20% above ideal weight and represents the most common nutritional disorder in domestic cats.

Overview and Clinical Importance

Feline obesity is defined as a body weight greater than 20% above ideal weight and represents the most common nutritional disorder in domestic cats. Approximately 30-40% of cats in developed countries are classified as overweight or obese, making it a significant concern in veterinary practice. Obesity predisposes cats to numerous comorbidities including diabetes mellitus, hepatic lipidosis, osteoarthritis, lower urinary tract disease, and dermatopathies. Understanding the pathophysiology, risk factors, diagnosis, and management of feline obesity is essential for NAVLE success and clinical practice.
