Feline Diabetes 101: Spotting the Signs and Managing Care
If your cat has been drinking more water than usual, leaving extra clumps in the litter box, or dropping weight despite a hearty appetite, it might not just be a phase. These subtle shifts are often the first red flags of a deeper issue- like diabetes.
At Star of Texas Veterinary Hospital in Austin, we know how easy it is to miss the early signs. That’s why we’re here to help you understand what feline diabetes looks like, how it’s diagnosed, and how to manage it with confidence and compassion.
Understanding Feline Diabetes
Diabetes mellitus in cats is a condition where the body either doesn’t produce enough insulin or doesn’t use it effectively. Insulin is the hormone that helps regulate blood sugar, so when it’s out of balance, glucose builds up in the bloodstream instead of fueling the body’s cells.
The result? A cat that’s technically full of energy but can’t access it. Over time, high blood sugar can damage organs, nerves, and immune function, making diabetes a serious- but manageable- diagnosis.
What Increases a Cat’s Risk?
Middle-aged and senior cats tend to be more prone to diabetes, especially if they’re overweight or live a low-activity lifestyle. Certain breeds like Burmese cats may be more susceptible, and long-term use of medications like corticosteroids can also increase risk. These are just a few of the factors we assess when we see signs of concern.
A great way to prevent diabetes is to keep your cat slim. Want to start your cat on the path to weight loss? Check out this Feline Fitness guide.
Recognizing the Early Signs
Because cats are experts at hiding discomfort, diabetes can creep in quietly. You might first notice your cat is emptying the water bowl more quickly, or the litter box seems wetter than usual. Weight loss, even with an increased appetite, is another common clue. Some cats develop weakness in their hind legs, walking with a flat-footed stance known as a “plantigrade posture.”
Sweet-smelling breath, reduced energy, and a tendency to hide more than usual can also be subtle but important indicators. If any of this sounds familiar, don’t wait- early diagnosis makes a big difference.

How We Diagnose Diabetes
When we suspect diabetes, our veterinary team will typically recommend a blood glucose test and urinalysis. These help us confirm elevated sugar levels and rule out other possible causes for your cat’s symptoms. We may also run a fructosamine test, which gives us a longer-term view of how blood sugar has been behaving over the past couple of weeks.
Thanks to our in-house services and diagnostic tools, we can get answers quickly and start a personalized care plan right away. Our Cat Friendly, Fear Free approach also means we’ll do everything we can to reduce stress for both you and your cat during the visit.
What Treatment Looks Like
Managing feline diabetes is a daily commitment, but with the right tools and guidance, it becomes second nature for most pet owners. Our team will walk you through every step, from giving injections to selecting the best diet. Many cats respond well to treatment, and some may even go into remission with early intervention and consistent care.
Here’s what a typical treatment plan includes:
| Component | What It Involves | Why It Matters |
| Insulin Injections | Usually given once or twice daily under the skin. We’ll teach you exactly how. | Helps regulate blood sugar, preventing dangerous highs and lows. |
| Prescription Diet | Most diabetic cats benefit from a low-carb, high-protein diet. | Supports stable glucose levels and reduces insulin resistance. |
| Meal Timing | Meals are typically given at the same time as insulin doses. | Synchronizing food and medication helps maintain consistent blood sugar. |
| Glucose Monitoring | May involve at-home checks or in-clinic glucose curves. | Ensures insulin dose is working and catches problems early. |
| Weight Management | Regular weigh-ins and portion control help maintain a healthy body condition. | Excess weight worsens insulin resistance and complicates management. |
| Routine Checkups | Periodic bloodwork, urinalysis, and physical exams. | Helps monitor for complications and adjust treatment as needed. |
Cats aren’t always cooperative patients, but we’ll help you develop a routine that works for you both. Tools like treat distraction, gentle restraint techniques, and calming environments can make the process smoother.
And here’s some good news: not all cats need lifelong insulin. If diabetes is caught early and managed consistently, some cats may go into remission- meaning they no longer need insulin at all. This is most likely when treatment starts soon after diagnosis and includes the right diet and weight management.
The Risks of Leaving It Untreated
Without proper care, diabetes can lead to diabetic ketoacidosis (DKA), a life-threatening emergency where the body begins breaking down fat at a dangerous rate. Other risks include recurring infections and diabetic neuropathy, which can make it painful or difficult for your cat to walk.

Common Questions We Hear
Can feline diabetes go into remission?
Yes. With early treatment, some cats can go into remission- especially if they respond well to diet and insulin.
Will I need to monitor blood sugar at home?
Sometimes. It depends on your cat’s individual plan, but home monitoring helps us fine-tune care.
Can stress impact blood sugar?
Absolutely. Cats are sensitive to change, and stress can lead to spikes in glucose. That’s why calm, predictable routines are so helpful.
How long can a cat live with diabetes?
With good management, many cats live for years with a great quality of life. It’s a team effort, and we’re right here with you.
