Feline diabetes is caused by a decreased response to the insulin that is being produced by the pancreas. Older, less active, and overweight cats are predisposed.



As the symptoms of diabetes are very similar to other disease processes, such as Cushing’s disease, hypothyroidism, kidney in addition to a thorough history and physical examination, your veterinarian will likely recommend:


While diabetic cats can produce insulin, they still benefit from insulin therapy to improve the body’s response to circulating insulin. Cats generally respond best to long-acting insulins, such as Lantus (glargine) and Levemir (detemir).

Cats also require dietary management, which generally consists of high protein/low carbohydrate diets. Studies have shown that over 60% of diabetic cats fed a high protein diet will have a decrease in their insulin requirements, some even going into insulin-dependent remission. Canned food tends to be preferred over dry as most high protein dry foods are very calorically dense and will most likely lead to increased weight gain.
