Diabetes mellitus in cats is a manageable but demanding condition that significantly affects quality of life if poorly controlled. With appropriate care, many diabetic cats achieve remission or stable, comfortable lives.
Poorly controlled feline diabetes causes significant suffering — polydipsia and polyuria disrupt comfort and normal behavior, while diabetic neuropathy causes weakness, pain, and difficulty walking. Diabetic ketoacidosis is a life-threatening emergency requiring intensive care. Conversely, well-managed diabetic cats can live happily for years, with remission achieved in many cases through dietary change and appropriate insulin therapy. The welfare burden falls partly on owners, who must learn injection technique, dietary management, and recognize hypoglycemia signs. Stress-induced hyperglycemia from clinic visits can complicate blood glucose interpretation; home monitoring avoids this confounder. Cats in remission require ongoing weight management and periodic glucose monitoring to detect relapse.
