Diabetes Mellitus in Cats
Commonly resembles Type 2 diabetes in humans and is often linked to obesity - unlike dogs, a meaningful proportion of diabetic cats can achieve remission with early, aggressive management.
Overview
Feline diabetes is usually associated with insulin resistance and obesity. With prompt diagnosis and aggressive early glycemic control, a meaningful proportion of cats can achieve diabetic remission - returning to a non-diabetic state, sometimes without ongoing insulin.
Clinical signs
- Polyuria and polydipsia
- Weight loss despite a normal or increased appetite
- Poor coat condition
- A plantigrade stance (walking on the hocks) from diabetic neuropathy in advanced or poorly controlled cases
- In diabetic ketoacidosis: lethargy, vomiting, and inappetence - a medical emergency
Diagnosis
- Persistent hyperglycemia together with glucosuria
- Fructosamine testing to help distinguish true diabetes from the stress hyperglycemia cats commonly show during vet visits
Treatment
- Insulin therapy, commonly glargine or PZI
- A low-carbohydrate, high-protein diet
- Weight management
- Home blood glucose monitoring, including at-home glucose curves or continuous glucose monitors
- Early, aggressive glycemic control to maximize the chance of diabetic remission
Prognosis
Good with proper management. A meaningful proportion of cats achieve diabetic remission, particularly when treatment and dietary management start promptly after diagnosis.

Frequently asked questions
Can diabetes in cats really go away?
Yes - a meaningful proportion of diabetic cats achieve remission, particularly with early diagnosis, dietary management, and tight glycemic control soon after diagnosis. Not all cats reach remission, but it is a realistic goal for many.
Why is diet so important for diabetic cats specifically?
A low-carbohydrate, high-protein diet reduces the blood sugar spikes that make diabetes harder to control, and is one of the most effective non-insulin tools for helping cats reach remission.
