A diabetes diagnosis can feel overwhelming at first. Injections, blood glucose monitoring, prescription foods, vet visits. It is a lot to take in, particularly when your cat is already unwell.
But feline diabetes is one of the more manageable chronic conditions in cats, and for some cats, going into full remission is genuinely possible. Diet is one of the most powerful levers you have, and understanding why makes the whole thing considerably less daunting.
What actually is feline diabetes?
Diabetes mellitus in cats is a metabolic disorder affecting how the body processes glucose. There are two types, but the vast majority of cats have Type 2, where the body either does not produce enough insulin or the cells become resistant to it. Insulin is the hormone that allows glucose to enter cells and be used for energy. When it is not working properly, glucose builds up in the bloodstream while the cells effectively starve.
Signs to watch for
Diabetes can develop gradually, which is part of why it sometimes goes undetected until it is fairly advanced. Common signs include:
- Increased thirst and urination
- Weight loss despite a normal or increased appetite
- Lethargy and weakness
- Changes in gait, particularly a plantigrade stance where the cat walks on their hocks rather than their toes
- Vomiting and dehydration in more advanced cases
If your cat is showing any combination of these signs, prompt veterinary attention is important. A diagnosis can usually be confirmed with a blood glucose test and urinalysis.
What causes it?
Several factors can contribute:
Diet. This is the big one. Cats are obligate carnivores. Their metabolism is designed around protein and fat, not carbohydrates. Commercial dry foods in particular are extremely high in carbohydrate-loaded fillers. When carbohydrates are consumed, they break down into glucose, causing blood sugar spikes that demand an insulin response. Over time, persistent demand can lead to insulin resistance and strain on the pancreatic beta cells, setting the stage for diabetes. For cats, eliminating or dramatically reducing carbohydrates is not just helpful. It is foundational.
Obesity. Overweight cats are significantly more susceptible. Excess body fat contributes directly to insulin resistance.
Age. Cats over seven to ten years are more commonly affected, though diabetes can occur at any age.
Corticosteroids. Steroids prescribed for allergies, inflammatory conditions or other health issues can disrupt glucose metabolism and induce insulin resistance. If your cat has been on long-term steroid therapy and is showing diabetic signs, this connection is worth discussing with your vet. Reducing or discontinuing steroids, where medically possible, can sometimes reverse steroid-induced diabetes.
Genetics. Certain breeds are predisposed. Burmese cats in particular have a well-documented genetic susceptibility.
Treatment
Managing feline diabetes typically involves a combination of insulin, dietary change, and careful monitoring.
Insulin
Most cats do well on Lantus (glargine), which is considered the gentlest option and gives the best chance of achieving remission. Your vet will usually admit your cat for one to three days initially to administer the first doses and monitor blood glucose response before sending you home with the skills and confidence to manage injections yourself.
Dietary change
A low carbohydrate diet is non-negotiable for a diabetic cat. Most vets will recommend a prescription food. Prescription diabetic foods are expensive, often unpalatable, and still contain more carbohydrates than a species-appropriate diet. A properly formulated raw or low carb wet food is a far better option.
Monitoring
Home glucose testing is more accurate and far less stressful than clinic testing. Stress alone can significantly elevate blood glucose, making clinic readings unreliable. Testing at home before every injection tells you whether it is safe to give insulin that day.
Keep a daily record covering:
- Dose and time of injections
- Food intake
- Energy levels and general behaviour
- Any vomiting, diarrhoea or unusual signs
- Water intake and urination
- Urine glucose if your vet has provided test strips
Never adjust your cat's insulin dose without discussing it with your vet first. Changes to dose carry real risk and need to be made carefully and with guidance.
A note on remission
Remission is real and it is worth working toward. Some cats achieve stable blood glucose without ongoing insulin, and that is a genuine possibility with the right diet and management. But remission is not the same as a cure. A cat in remission is still a diabetic cat. Testing should continue, because blood glucose can shift over time and a cat who no longer needs insulin today may need it again in the future. Catching that early is what keeps them safe. Stopping monitoring because things are going well is unfortunately how cats end up back in crisis.
Why raw feeding matters for diabetic cats
Switching a diabetic cat to a raw diet removes the primary dietary driver of blood glucose instability. But the benefits go beyond carbohydrate reduction, and it is worth understanding why this way of feeding makes such a difference for these cats specifically.
Blood glucose control. Raw diets are naturally very low in carbohydrates. With less glucose entering the bloodstream, blood sugar levels stabilise and the pancreas is no longer under constant pressure to produce insulin. For many cats, this translates directly into reduced insulin requirements, and for some, remission becomes achievable.
Hydration and kidney support. Raw food has a significantly higher moisture content than dry food. Diabetic cats are prone to dehydration due to increased urination, and good hydration is particularly important for kidney function. A moisture-rich diet helps support this without any extra effort on your part.
Weight management. High protein, low carbohydrate diets help diabetic cats maintain lean muscle mass while losing excess body fat. The protein and fat content also promotes satiety, reducing the likelihood of overeating, which matters because obesity is both a cause and a complicating factor in feline diabetes.
Digestibility. Raw diets are free from the fillers and artificial additives found in most commercial foods. Without those, digestion tends to be more efficient, nutrient absorption improves, and the gut is generally less burdened. For a cat whose body is already under metabolic stress, that matters.
Coat, skin and energy. These are often the changes owners notice first after switching. A diet rich in quality animal protein and essential fatty acids tends to produce a visibly improved coat and skin condition, and many diabetic cats, who can be lethargic and dull before diagnosis, show a meaningful improvement in energy and vitality once their diet and blood glucose are better managed.
Where Raw Meow fits in
Our range is low carbohydrate by design, which makes it well suited to diabetic cats. There are a few ways to use it depending on what works for you and your cat.
The simplest starting point is our Freeze Dried meals. Rehydrate and feed, with nothing to formulate or calculate. For a newly diagnosed cat where you are already managing insulin, monitoring and a diet transition simultaneously, simple matters.
If you prefer to source your own meat and have more control over what goes in the bowl, our Raw Meow Mix is the base. You add the protein of your choice, and the mix provides the organ, bone mineral, and supplement component to make the meal complete. It is a good option once you know what your cat tolerates and you want to build a longer term routine around it.
For cats with additional sensitivities alongside their diabetes, our Hypoallergenic Raw Meow Mix uses roo liver and contains no egg and no green lipped mussel, keeping the ingredient profile as simple as possible.
If you are not sure what your cat will actually eat yet, the Dip Your Paw pack is a low-commitment way to try a few options before buying in bulk. Diabetic cats can be particular about food, and the last thing you want during a diet transition is a cat who refuses to eat.
We also recommend Ava's Blend as a probiotic to support gut health through the transition. It does contain bovine colostrum, so factor that in if your cat has a known sensitivity to dairy-derived ingredients.
One important note across all of this: blood glucose can drop quickly once carbohydrates are removed from the diet. This is a good thing, but it means your monitoring needs to be consistent, particularly in the early weeks of transition. A raw-friendly vet on board from the start makes this considerably safer.
The community
Feline diabetes has one of the most active and knowledgeable cat owner communities going. The Feline Diabetes Facebook group is an excellent resource, particularly when you are learning to monitor and adjust at home. People there have been through exactly what you are navigating and are generous with their experience.
Our own Australian Raw Fed Cats Facebook group is also a great place to land if you are managing a diabetic cat on raw. We talk about this regularly, and there are plenty of members who have been through the insulin, the monitoring, the diet transition and everything in between.
The path to better diabetes control is absolutely doable. Get a supportive vet, get the diet right, learn your cat's numbers, and reach out when you need help.
