Feline diabetes mellitus is a manageable condition when diagnosed early. With appropriate diet and insulin therapy, many cats achieve remission and most maintain good quality of life.
Feline diabetes is one of the most manageable serious feline conditions when properly treated, but poorly managed diabetes causes significant suffering. Untreated diabetes leads to weight loss, weakness, and eventually diabetic ketoacidosis — a life-threatening emergency with profound suffering. Cats in remission — which occurs in a substantial proportion of cases with early, aggressive dietary management — return to normal quality of life entirely. The welfare improvement possible through remission motivates early diagnosis and consistent management. Insulin injections twice daily are manageable for most owners and typically cause minimal distress to cats when administered properly. The key welfare message is that obesity prevention is the most powerful intervention: most feline diabetes is preventable through appropriate feeding and weight management throughout a cat's life.
