"The long-term complications of feline diabetes are a result of prolonged hyperglycemia"
Due to their shorter life span, diabetic cats seem to develop fewer long-term complications than human diabetics. Obtaining optimal regulation of blood glucose concentration helps to prevent the long-term complications of Diabetes mellitus.
Neuropathy is occasionally seen in feline diabetes.
The pathogenesis of diabetic neuropathy remains unknown and is likely multifactorial (including persistent hyperglycemia and resultant metabolic damage to nerves).
Treatment
There is no specific treatment. The prognosis is guarded but
partial or full resolution of the clinical signs has been reported
following regulation of blood glucose concentrations with insulin.
A very serious complication
of Diabetes mellitus that may be seen in cats. The clinical signs
are those of renal insufficiency.
Cataracts are seen far more common in canine diabetes than feline diabetes.
