Feline Diabetes Mellitus: Welfare and Achieving Remission

Diabetes mellitus in cats is a common endocrine disorder, but unlike dogs, many cats achieve remission with appropriate insulin therapy and dietary management — a remarkable welfare outcome.

Key Facts

Feline diabetes is type 2 in most cases, driven by insulin resistance and obesity
Clinical signs include increased drinking and urinating, weight loss, and diabetic neuropathy
Diabetic neuropathy causes plantigrade posture — walking on hocks — which is painful and reversible
Up to 80% of cats with uncomplicated diabetes can achieve remission with tight glycaemic control
Low-carbohydrate diets significantly improve insulin sensitivity and support remission

Welfare Considerations

Feline diabetes causes significant welfare compromise through polyuria and polydipsia disrupting normal behaviour, diabetic neuropathy causing pain and altered gait, and the progressive weight loss of uncontrolled disease. The remarkable welfare feature of feline diabetes is the high probability of remission with appropriate management — tight glycaemic control through twice-daily insulin and low-carbohydrate diet allows recovery of beta cell function in many cats. Early diagnosis and remission-oriented management can return cats to near-normal welfare within weeks to months. Monitoring for hypoglycaemia is essential to prevent this treatment complication.

What You Can Do

Monitor cats for signs of diabetes including increased drinking, urinating, and hindlimb weakness
Begin low-carbohydrate dietary management immediately at diagnosis to support remission
Monitor blood glucose curves at home or at the vet to achieve tight glycaemic control
Check for signs of hypoglycaemia including weakness and disorientation after insulin administration
Work with your vet on gradual insulin reduction when remission criteria are approaching
