Cats with diabetes can develop other health conditions — usually after living with diabetes for a year or more — as a result of prolonged high blood glucose levels. Careful control of blood glucose levels will help minimize potential complications.

Weakness of the hind legs is a common serious complication of feline diabetes. Persistently high blood glucose levels may damage nerves, resulting in weakness and muscle wasting, usually in the hind legs. Avoiding high blood glucose levels can help prevent or reduce the severity of hind limb weakness.
