Diabetes Mellitus in Burmese
Diabetes mellitus is one of the most common endocrine diseases in cats, and Burmese cats specifically have one of the highest documented breed prevalences. In Burmese, diabetes appears earlier and at higher rates than the general cat population. Early recognition, proper insulin therapy, and dietary management can lead to diabetic remission in many cases.
Why Burmese are predisposed to diabetes mellitus
Genetic. Burmese cats in multiple studies (Australia, UK) have shown 3-5x the diabetes risk of the general cat population. The genetic basis is incompletely understood. Compounding factors that increase risk in any cat (obesity, dry-food-only diet, indoor lifestyle, advancing age) interact with the breed predisposition.
What you'll see at home
- Increased thirst and water consumption
- Increased urination, larger clumps in the litter box
- Increased appetite
- Weight loss despite increased eating (the classic combination)
- Lethargy
- Poor coat condition
- Plantigrade stance (walking on the hocks — diabetic neuropathy)
- Diabetic ketoacidosis (vomiting, weakness, dehydration) — emergency
Red flags — go to an emergency vet
- ⚠ Vomiting plus profound lethargy — possible diabetic ketoacidosis
- ⚠ Inability to stand
- ⚠ Sweet-smelling breath
- ⚠ Rapid breathing in a known or suspected diabetic cat
- ⚠ Collapse
How vets diagnose diabetes mellitus
Bloodwork: persistent hyperglycemia (high blood sugar) plus glucosuria (sugar in urine). Stress hyperglycemia complicates diagnosis in cats — a single high glucose isn't enough. Fructosamine measures average glucose over 2-3 weeks and confirms persistent hyperglycemia. Urine culture rules out concurrent UTI.
Treatment options
Long-acting insulin (glargine, detemir, or PZI most commonly) twice daily by injection. Low-carbohydrate, high-protein diet — wet food is preferred. Home glucose monitoring with a pet glucometer or continuous glucose monitor. Goal is glycemic control plus weight optimization. Diabetic remission is possible — and more common in cats than dogs — particularly with early treatment, weight loss, and dietary change.
Living with a Burmese who has diabetes mellitus
- 1 Twice-daily insulin injections — most owners learn this quickly
- 2 Low-carb, high-protein diet — typically wet food; certain prescription diets (Hill's m/d, Royal Canin Glycobalance) are specifically designed for this
- 3 Home glucose monitoring is the gold standard — much more accurate than relying on in-clinic curves
- 4 Continuous glucose monitors (FreeStyle Libre) are increasingly used in cats
- 5 Monitor for diabetic remission — some cats no longer need insulin after weeks to months of good control
- 6 Stress hyperglycemia is real in cats — home monitoring avoids overdosing based on stress-elevated clinic readings
- 7 Pet insurance — diabetic cats need lifelong monitoring; insurance helps
Can RexVet help with this online?
RexVet is well-suited for: refilling insulin prescriptions for established diabetic cats, coaching on home glucose monitoring, diet transition guidance, dose-adjustment conversations with home glucose data, and quality-of-life check-ins.

Prognosis — what to expect
With proper insulin therapy, dietary management, and home monitoring, diabetic cats can live normal life spans. Diabetic remission (no longer needing insulin) occurs in a meaningful percentage of cats with early treatment and weight loss — particularly in Burmese cats with good control in the first weeks. Quality of life is generally excellent once stable.
Frequently asked questions
Frequently asked questions
What are the early signs of diabetes in a Burmese cat?
The classic combination: drinking more water, urinating larger amounts (you'll notice bigger clumps in the litter box), eating more but losing weight. Lethargy and poor coat condition often accompany. If you see these in a Burmese, get bloodwork — the breed risk is high enough that early screening makes sense.
Can my diabetic Burmese cat go into remission?
Yes — diabetic remission (no longer needing insulin) is genuinely possible in cats, more so than in dogs. The likelihood is highest with early diagnosis, weight loss, low-carb diet, and good glycemic control in the first weeks. Burmese cats may actually have higher remission rates than other breeds when treated proactively.
Is home glucose monitoring worth the effort?
Yes — particularly for cats. Stress hyperglycemia at the vet clinic is real and significant in cats; home monitoring gives much more accurate dosing information. A FreeStyle Libre continuous glucose monitor or a pet glucometer with a small ear-prick test changes how well diabetic cats can be managed.
