Feline diabetes is a manageable condition in most cats, and with appropriate insulin therapy and dietary management, many cats achieve excellent quality of life — and some achieve diabetic remission.
Feline diabetes creates a welfare journey that varies enormously depending on management quality. Uncontrolled diabetes causes chronic suffering through hyperglycaemia: osmotic diuresis causes persistent thirst and urination, glucose-depleted tissues cause muscle wasting and weakness, and neuropathy causes the characteristic plantigrade stance (pain and weakness in hind legs). DKA represents acute crisis-level suffering requiring emergency intervention. With good management, however, most diabetic cats return to excellent quality of life — owners who commit to twice-daily insulin injections and dietary management typically describe their cats as bright, comfortable and engaged. The prospect of remission is a genuine welfare-positive outcome: approximately half of cats managed intensively with low-carbohydrate wet food and glargine insulin achieve remission within 6 months. Hypoglycaemia (low blood sugar from too much insulin) is the primary iatrogenic welfare risk — home glucose monitoring enables safe dose titration and dramatically reduces hypoglycaemic crises.
