Feline Diabetes: Unique Challenges and Treatment Advances
Cat diabetes is different from dog diabetes. Some cats can achieve remission with proper treatment. Learn about the latest approaches.
Feline diabetes differs from canine diabetes in important ways. Cats most commonly develop Type 2 diabetes (insulin resistance), and with aggressive early treatment, some cats can achieve remission — meaning they no longer need insulin injections. Understanding the unique aspects of feline diabetes leads to better outcomes.
Key Points
- Cats usually develop Type 2 diabetes (insulin resistance)
- Remission is possible with early, aggressive treatment
- High-protein, low-carb diets are key for cats
- Insulin glargine (Lantus) has the highest remission rates
- Obesity is the biggest risk factor
- New SGLT2 inhibitors are changing treatment for some cats
Feline vs. Canine Diabetes
While dogs mostly get Type 1 diabetes (no insulin production), cats usually get Type 2 (insulin resistance, often from obesity). This means the pancreas still produces insulin, but the body can't use it properly. With weight loss and proper treatment, some cats' insulin sensitivity improves enough to achieve remission.
Signs in Cats
Increased thirst and urination are the classic signs, but owners often notice these late because cats are naturally secretive drinkers. Other signs: increased appetite with weight loss, lethargy, walking flat on the hocks (plantigrade stance — a sign of diabetic neuropathy), and poor coat condition. Plantigrade stance is unique to cats and indicates nerve damage from high blood sugar.
Treatment for Remission
To maximize remission chances: start insulin glargine (Lantus) early, switch to a high-protein, low-carbohydrate diet (canned food is generally lower in carbs than dry), achieve gradual weight loss if overweight, and monitor closely. Studies show up to 50-60% of cats can achieve remission with early, aggressive treatment. Remission can last months to years.
SGLT2 Inhibitors
New oral medications called SGLT2 inhibitors (like velagliflozin/Bexacat and senagliflozin/Senvelgo) are changing feline diabetes treatment. They work by making the kidneys excrete excess glucose in urine, lowering blood sugar without insulin injections. They're suitable for cats with Type 2 diabetes but must be used carefully — they're not appropriate for all cats. Discuss with your vet.
When to See a Vet Immediately
- Increased thirst and urination
- Weight loss despite eating well
- Walking flat on the hocks
- Poor coat condition
- Lethargy
- Your cat is overweight and you want to prevent diabetes
