Feline Diabetes Mellitus: Welfare Management and Remission

Diabetes mellitus in cats requires careful management to prevent severe welfare impacts from hyperglycaemia, with many cats achieving remission through dietary control and insulin.

Key Facts

Feline diabetes is typically Type 2 analogous to human Type 2 diabetes
Obese cats and those fed high-carbohydrate diets are at increased risk
Clinical signs include polyuria, polydipsia, weight loss, and hindlimb weakness from neuropathy
Up to 80% of cats achieve remission with aggressive early treatment using insulin and low-carbohydrate diet
Diabetic neuropathy causing plantigrade stance is reversible with good glycaemic control

Welfare Considerations

Uncontrolled feline diabetes causes progressive welfare deterioration through hyperglycaemia, weight loss, neuropathy, and eventual diabetic ketoacidosis. Diabetic neuropathy causing hindlimb weakness and plantigrade gait impairs mobility and quality of life. Hypoglycaemic episodes from insulin overdose cause acute welfare emergencies. With appropriate management including twice-daily insulin and a low-carbohydrate diet, many cats achieve remission allowing discontinuation of insulin. Long-term managed diabetes causes minimal welfare impact in well-controlled cats.

What You Can Do

Transition diabetic cats to a low-carbohydrate high-protein diet as the primary management tool
Monitor blood glucose regularly using home glucose monitoring to optimise insulin dose
Learn to recognise signs of hypoglycaemia and keep glucose syrup accessible for emergency use
Work toward remission as the goal of treatment rather than accepting lifelong insulin dependence
Schedule regular veterinary checks to monitor glycaemic control and detect complications early
