Diabetes occurs when the body cannot use glucose, the main source of energy for a body’s cells. When there is not enough glucose transported into the cells, there is not enough energy for the cells to function normally; in turn, the tissues become starved for that energy. A dog or cat will not be able to live long if this goes untreated.
Diabetes Mellitus is a disease which involves the lack of insulin in the body. To understand how this affects your pet it is necessary to understand how the body normally functions.
