Feline Diabetes Mellitus and Welfare Management

Diabetes mellitus in cats is manageable with insulin therapy and dietary modification, but requires committed owner involvement to maintain quality of life and achieve remission.

Key Facts

Type 2 diabetes is the most common form in cats, often linked to obesity and high-carbohydrate diets
Prevalence is estimated at 1 in 200-400 cats, increasing with age and obesity
Clinical signs include increased thirst, frequent urination, weight loss despite good appetite, and lethargy
Insulin therapy (typically twice daily injections) combined with low-carbohydrate diet is the standard treatment
Diabetic remission — return to non-diabetic status without insulin — occurs in 25-50% of well-managed cats
Low-carbohydrate wet food diets significantly improve glycaemic control and remission rates
Regular glucose monitoring at home with ear-prick glucometers or continuous glucose monitors improves outcomes

Welfare Considerations

Unmanaged feline diabetes causes chronic suffering through hyperglycaemia, peripheral neuropathy causing plantigrade stance, and potentially life-threatening diabetic ketoacidosis. With appropriate management, many diabetic cats achieve excellent quality of life and even remission. Owner commitment to twice-daily injections, dietary change, and glucose monitoring is demanding but essential. Cats achieving remission have better long-term welfare outcomes. Early diagnosis through routine senior wellness screening prevents advanced disease presentation.

What You Can Do

Have senior cats screened for diabetes annually through blood glucose and urine glucose testing
Transition your cat to a high-protein, low-carbohydrate diet to reduce diabetes risk
Work with your vet to learn injection technique and home glucose monitoring if your cat is diagnosed
Join online support communities such as Feline Diabetes Message Board for peer support and guidance
Maintain healthy body weight in your cat through appropriate feeding to reduce diabetes risk
