My 6 year old cat was diagnosed with diabetes mellitus

Question: 

My 6 year old cat was diagnosed with diabetes mellitus 3 months ago by my veterinarian. My cat was placed on glargine insulin and now appears to be in ‘remission’ with his diabetes. Was my cat initially misdiagnosed?

Answer: 

Diabetes mellitus is a disease characterized by hyperglycemia (high blood sugar) due to insufficient amounts of insulin or insulin activity. In cats, diabetes arises from a combination of decreased insulin sensitivity and decreased insulin secretion. With effective therapy, cats can go into states of diabetic remission where they no longer require insulin therapy. The definition of remission is variable, but generally implies normal blood sugar values (the definition of ‘normal’ blood sugar values is variable too) for a period of 2 to 4 weeks after insulin or other blood sugar-lowering therapy is stopped. Current literature suggests that remission rates for diabetic cats ranges from 25% to 100%. In some studies remission rates were variable depending on the type of insulin therapy used. Remission may occur when there is resolution of concurrent disease or cessation of medications (such as steroids) that are causing decreased insulin sensitivity or secretion.
