Feline Diabetes: Welfare and Management

Diabetes mellitus in cats is increasingly common, linked to obesity and high-carbohydrate diets. With good management, many cats achieve remission or live comfortably for years.

Key Facts

Feline diabetes is typically Type 2 (insulin resistance) rather than Type 1 (insulin deficiency)
Obesity is the single biggest risk factor - overweight cats are up to 4 times more likely to develop diabetes
Classic signs include increased thirst, urination, weight loss despite good appetite, and plantigrade stance
A high-protein, low-carbohydrate diet can significantly improve glycaemic control and may induce remission
Approximately 25-50% of diabetic cats achieve remission with appropriate dietary management and insulin therapy
Hypoglycaemia (low blood sugar) is the most dangerous short-term complication of insulin treatment
Regular home glucose monitoring or continuous glucose monitoring devices are increasingly used in cat management

Welfare Considerations

Uncontrolled feline diabetes causes significant suffering through chronic thirst, muscle weakness, peripheral neuropathy (causing the characteristic plantigrade stance), and increased infection susceptibility. The good news is that unlike dogs, cats have a real prospect of diabetic remission, particularly when dietary changes are made early. The welfare of well-managed diabetic cats depends heavily on owner commitment to monitoring and the ability to recognise and respond to hypoglycaemic episodes.

What You Can Do

If your cat is obese, work with your vet on a structured weight loss plan to reduce diabetes risk
Ask your vet about transitioning a diabetic cat to a high-protein, low-carbohydrate canned food diet
Learn to recognise signs of hypoglycaemia (weakness, wobbling, seizure) and keep glucose syrup on hand
Consider home blood glucose monitoring to reduce stress of repeated vet visits for diabetic cats
