Research overview: insulin glargine and diabetic remission in cats

Research showed that tight glycemic control, often using long-acting insulin glargine combined with a low-carbohydrate diet and initiated early in newly diagnosed cats, can achieve diabetic remission, a state in which cats no longer require insulin. Reversing glucotoxicity allows recovering beta cells to resume function. This overview compiles the treatment literature rather than one source, describing how aggressive early control promotes remission, why diet and insulin choice influence success rates, and how home glucose monitoring supports safe intensive therapy. It matters because remission transformed the goals of feline diabetes care from lifelong glucose management to potential cure in a meaningful fraction of cats, emphasizing the value of early, vigorous treatment and reinforcing the type 2-like, partially reversible nature of the disease.
