Therapy for a diabetic patient can be considered successful when the clinical signs of diabetes mellitus improve significantly.
After the animal has been stabilized successfully, routine checks should be carried out every 3-6 months.
Careful monitoring and control during maintenance will help to limit the chronic problems associated with diabetes.
The aim of therapy is not to produce a series of blood glucose concentrations that are within the reference range. An example of a stable diabetic cat is a blood glucose range of 5 - 14 mmol/l (90-252 mg/dl) for most of each 24 hour period.
See blood glucose curves for details on making a glucose curve.

The goal is produce a blood glucose curve that approaches the reference range but avoids potentially fatal hypoglycaemia.
