Feline diabetes is a manageable condition that, with appropriate insulin therapy, dietary management, and monitoring, allows many cats to achieve diabetic remission or maintain good long-term quality of life.
Feline diabetes imposes welfare costs through multiple routes: the hyperglycaemia of uncontrolled disease causes osmotic symptoms including extreme thirst and polyuria, progressive weight loss, weakness, and the painful neuropathy affecting hind limb function. Treatment requires twice-daily insulin injections, which most cats tolerate well with appropriate handling technique, but represent a significant commitment for owners. The welfare goal is tight glucose regulation that prevents both the symptoms of hyperglycaemia and the dangerous acute effects of hypoglycaemia. Monitoring blood glucose at home using flash glucose monitoring systems (FreeStyle Libre adaptations) allows more precise management without the stress of repeated veterinary visits for curve assessments. Dietary transition to high-protein, low-carbohydrate food is one of the highest-impact interventions — many cats achieve remission when diet and insulin are optimised promptly after diagnosis. Remission is experienced by cats as a return to normal function and wellbeing; the welfare improvement is substantial. Diabetic cats that do not achieve remission can still have excellent quality of life with attentive ongoing management.
