Diabetes in Dogs & Cats: Curves, Monitors, and Remission Goals

Glucose Curves, Home Monitoring, and Remission: The Diabetes Journey

Getting a diabetes diagnosis for your pet can feel overwhelming at first. Suddenly there are insulin injections to give, feeding schedules to follow, and blood sugar numbers to track. It’s a lot to take in, and it’s completely normal to feel uncertain about what comes next.

Here’s what we want you to know: with the right support and a good routine, most diabetic pets live happy, comfortable lives. Glucose curves help us see if insulin is working the way it should. Home monitoring gives you real-time feedback between vet visits. And for diabetic cats, there’s even the possibility of remission, where careful early management might eventually mean no more insulin at all.

Rustebakke Veterinary Service in Clarkston brings both small animal expertise and community-based compassion to diabetes care. Our diagnostic capabilities include in-house testing for same-day glucose curves and interpretation. We guide families through home monitoring, insulin adjustments, and nutrition for steady control. For cats with remission potential, we provide close follow-up to taper insulin safely while watching for relapse. Request an appointment to set up a plan or contact us with urgent questions about blood sugar.

What Makes Diabetes Different in Dogs and Cats?

Diabetes mellitus happens when the body can’t properly use glucose, the sugar that fuels every cell. Insulin is the key that unlocks cells so glucose can enter. When there’s not enough insulin, or the body ignores its signal, glucose builds up in the bloodstream instead. That’s why diabetic pets drink more, urinate more, lose weight despite eating well, and often seem tired.

Here’s where dogs and cats differ: dogs usually have insulin deficiency, meaning their pancreas makes little to no insulin. They’ll need insulin injections for life. Cats more often have insulin resistance, frequently tied to obesity, along with reduced insulin production. Extra body fat interferes with insulin’s ability to do its job.

This species difference matters a lot for treatment. Some cats with diabetes can achieve remission with early, aggressive care, while most dogs need lifelong insulin. Knowing this from the start helps set realistic expectations. At Rustebakke, we consider species, weight history, and other health conditions when building your pet’s care plan. With consistency and teamwork, diabetes in pets doesn’t have to stand in the way of a full, happy life.

How Do You Know When Blood Sugar Is Actually Stable?

A single glucose reading is just a snapshot, not the whole picture. Stress from being at the clinic, a recent meal, or even excitement can temporarily push numbers up. That’s why blood glucose curves are so valuable.

A curve measures blood glucose every one to two hours over 12 to 24 hours and plots the results. This shows us:

• The lowest point of the day (called the nadir) and when it happens
• How long the insulin is actually working
• Whether glucose stays mostly in the target range
• If the dose or timing needs adjustment

Our diagnostic services include day-long supervised curves. Your pet stays with us for serial checks so variables like missed meals or timing errors don’t skew results. We pair the numbers with how your pet looks and acts throughout the day. You’ll leave with a clear explanation and concrete next steps.

We also may recommend fructosamine or A1C testing, which allows us a look into how well blood glucose levels have been maintained over a longer period of time.

Can You Monitor Glucose at Home?

Yes, and honestly, it’s a game-changer for many families. Pet glucometers let you check glucose before giving insulin, which keeps dosing safe and gives you peace of mind. Most pets tolerate the tiny blood samples needed from the ear, paw pad, or lip. The learning curve is short with a little practice, and we’re here to help you get comfortable.

For cat owners especially, learning how to test your cat’s blood glucose at home can make a real difference in daily management. We’ll walk you through the technique and troubleshoot any challenges during your visits.

Continuous glucose monitors are another option that’s becoming more popular. These small sensors attach to your pet and track readings every few minutes for up to two weeks. Apps on your phone show real-time numbers and trend arrows, which is especially helpful for catching overnight changes you’d otherwise miss. They cost more than traditional meters, but the continuous data can be incredibly valuable for pets with fluctuating numbers or cats approaching remission.

Urine test strips can also be useful at home. When glucose is too high in the body, it also shows up in urine. While urine testing doesn’t give us specific glucose numbers for your pet like blood testing does, it can tell us if it’s too high and signal that your pet’s insulin may need adjusting or that a blood glucose curve should be done. It’s basically a red flag that signals that more testing should be done.

We teach sampling technique, device use, and how to build a simple monitoring schedule during your first diabetes visits. Between clinic rechecks, your home data guides safe adjustments and alerts you to problems before they become emergencies.

What Does Remission Actually Mean for Diabetic Cats?

Remission is one of the most hopeful aspects of feline diabetes. It means a diabetic cat maintains normal glucose levels without needing insulin anymore. Now, remission doesn’t mean diabetes is cured forever. But with early, careful treatment and the right diet, the pancreas can recover enough function to work on its own, sometimes for months or even years.

Signs a cat may be a good candidate for remission:

• Short time between first symptoms and starting treatment
• Relatively low insulin requirements
• No other major health issues complicating the picture
• Healthy weight loss in overweight cats

Reaching remission takes close monitoring and very gradual dose reductions. We taper carefully and watch for any signs of rising glucose. Some cats do need insulin again later, especially with weight gain, illness, or stress. But our early, proactive approach gives your cat the best odds while keeping them safe throughout the process.

When Should You Worry About Hypoglycemia?

Hypoglycemia, or low blood sugar, is the most urgent risk of insulin therapy. It happens when insulin exceeds what your pet actually needs.

Early signs include:

• Restlessness or unusual anxiety
• Trembling or shaking
• Sudden intense hunger

More serious signs include:

• Weakness or wobbliness
• Confusion or disorientation
• Stumbling or difficulty walking
• Seizures or collapse (this is an emergency)

Common triggers:

• Insulin given without enough food eaten
• Extra exercise without extra calories
• Accidental double-dosing
• Improving insulin sensitivity (like when approaching remission)
• Illness that reduces appetite

Keep corn syrup or honey at home at all times. At the first signs of low blood sugar, rub a small amount on the gums and offer food. If your pet can’t swallow safely, apply syrup to the gums and head to the vet immediately. Don’t wait to confirm with a meter if the signs are obvious.

We review hypoglycemia symptoms and emergency steps at your first diabetes visit and give you a written plan to keep handy. If you suspect a problem, use our urgent care options Monday through Saturday morning so we can help fast.

What About Diabetic Ketoacidosis?

Diabetic ketoacidosis (DKA) is a serious complication that happens when severe insulin deficiency forces the body to burn fat for energy. This process creates ketones, which are acids that build up in the blood and can become life-threatening.

Early signs:

• Poor appetite or refusing food
• Unusual tiredness or lethargy
• Increased thirst and urination

As it progresses:

• Vomiting
• Rapid or labored breathing
• Severe weakness
• Sweet or fruity breath odor

DKA is most common in pets who haven’t been diagnosed yet or when insulin doses are missed, but infections or other illnesses can trigger it in treated diabetics too. It requires immediate care with IV fluids, insulin, and careful monitoring.

We’re equipped to assess and stabilize quickly with in-house testing for glucose, ketones, and electrolytes. Some severe cases may need transfer to a 24-hour facility for round-the-clock care. We’ll guide you through what’s happening, what treatment involves, and what to expect.

What Other Problems Can Diabetes Cause?

Diabetes can affect several body systems beyond blood sugar, which is why good control matters so much.

Diabetic neuropathy in cats: Some diabetic cats develop diabetic neuropathy, which causes weakness in the back legs and a distinctive flat-footed stance (walking on their hocks instead of their toes). The good news is that this usually improves as glucose control improves, though it can take weeks to months to see progress.

Diabetic cataracts in dogs: Dogs can develop diabetic cataracts, sometimes surprisingly quickly. High glucose levels cause changes in the lens that lead to cloudiness. While cataracts aren’t life-threatening, they affect vision and quality of life. If cataract surgery is being considered, glucose should be well controlled first.

Urinary tract infections: Diabetic pets are prone to urinary tract infections, sometimes with few obvious symptoms. The sugar in their urine creates a welcoming environment for bacteria. Regular screening and prompt treatment can meaningfully improve glucose control, since infections make blood sugar harder to regulate.

Can Diabetes Be Prevented or Better Controlled?

While not every case is preventable, you can definitely lower the risk, especially in cats. The single biggest factor is maintaining a healthy weight. Obesity dramatically increases a cat’s chances of developing diabetes, and even modest weight loss can improve insulin sensitivity. We include nutrition counseling during wellness visits to help prevent weight gain and support long-term health. Catching weight creep early is much easier than addressing significant obesity later.

Insulin swings can be prevented at home by keeping a strict schedule- your pet’s exercise amounts and timing should be the same day to day, and maintain regular meal routines. Burning more calories with a long hike, eating extra snacks, or missing meals can mean dangerous blood sugar changes.

Proper handling of insulin is also a big deal. Most insulin needs to be refrigerated- leaving it out on the counter can cause it to lose effectiveness, which risks causing blood sugar spikes. Most insulin should also be rolled to gently mix it- don’t shake it. Ask us about how your insulin should be best handled. When you buy insulin syringes, make sure you buy the right type. There’s a big difference between U40 and U100 insulin syringes, and accidentally buying the wrong ones can mean seriously under or overdosing your pet.

Here’s one that often surprises pet owners: dental disease can make diabetes significantly harder to control. Infected gums and teeth create chronic inflammation throughout the body, which increases insulin resistance. The bacteria from dental infections can also spread to other organs and worsen overall health. We’ve seen diabetic pets whose glucose suddenly became much easier to regulate after addressing significant dental problems. Our dental care services include thorough cleanings and treatment of infected teeth, which can be an important part of your diabetic pet’s overall management plan.

Preventive testing is part of our annual wellness care, and we may screen more frequently for seniors or pets with risk factors. Sometimes we catch early changes in glucose that can be addressed with diet and weight management before insulin becomes necessary.

FAQs: Quick Answers for Pet Parents

How often should I check my pet’s glucose at home? Early on, many families test before each insulin dose and occasionally mid-day or overnight to understand patterns. Once control is stable, we’ll work together to find a simpler schedule that still keeps your pet safe without taking over your life.

Do I need a continuous glucose monitor? Not necessarily. Traditional meters work well for many pets and are more affordable. A continuous monitor is especially helpful if your pet’s numbers fluctuate unpredictably, you’re concerned about nighttime lows, or you’re working toward remission and need detailed data.

What should I do if my pet skips a meal? Call us for specific guidance based on your pet’s situation. In general, if your pet eats significantly less than usual, you may need to reduce the insulin dose to avoid hypoglycemia. Never give full insulin to a pet who hasn’t eaten.

Can my cat really go into remission? Many cats can, especially with early diagnosis, a low-carbohydrate diet, and close monitoring. We’ll discuss your cat’s individual chances honestly and create a safe plan for working toward that goal.

How will I know if the insulin dose is right? Your pet should feel good: drinking and urinating normally, maintaining steady weight, eating well, and showing no signs of low blood sugar. Glucose curves and home readings confirm that numbers are staying in the target range. If something seems off, we adjust.

Does dental disease really affect diabetes? Yes, significantly. Chronic infection and inflammation from dental disease increase insulin resistance, making blood sugar harder to control. Treating dental problems often improves diabetic regulation noticeably.
