The Role of Diet in Feline Diabetes Mellitus
Feeding practices, weight management, and low-carbohydrate food choices can significantly improve long-term health and treatment outcomes for cats with diabetes.
Feline diabetes mellitus is most often type 2—insulin-resistant diabetes associated with chronic hyperglycemia and obesity.
Diet plays a critical role not only in prevention but also in ongoing management. With over 61% of cats classified as overweight or obese, veterinarians are on the front lines of a preventable epidemic.
A key contributor is free feeding (ad libitum) dry kibble, a common practice among cat owners, which encourages overeating, weight gain, and eventual insulin resistance.
