Diabetes mellitus in cats is a manageable chronic condition. With appropriate treatment, many cats achieve remission — but owner commitment and veterinary support are essential.
Uncontrolled diabetes causes progressive welfare deterioration through weight loss, lethargy, weakness, and if untreated, diabetic ketoacidosis — a life-threatening emergency causing vomiting, dehydration, and severe systemic illness. Cats with well-controlled diabetes can live comfortable, high-quality lives with relatively normal activity levels. The welfare priority is early diagnosis and consistent management. Owner compliance with twice-daily insulin injections, blood glucose monitoring, and dietary management determines outcomes. Many cats achieve remission within weeks to months of starting appropriate treatment — a genuine cure rather than lifelong management. Hypoglycaemia from insulin overdose is an acute welfare emergency requiring rapid response. Cats who achieve remission must continue monitoring as recurrence is common, particularly if obesity is not resolved.
