Best Diabetic Cat Food

A diabetes diagnosis for your cat is never a good thing, but it doesn’t need to be a source of serious upset or panic. If a veterinarian determines that your cat needs treatment for diabetes, the most immediate impact is likely to be felt by you, rather than your feline friend. Owners are given the task of managing daily insulin levels, as well as an increased responsibility for their pet’s diet.

Diabetic cats require day-to-day monitoring and a more active lifestyle, but the food they eat is arguably the biggest contributing environmental factor in stable blood sugar levels and overall health. In most cats, the condition is similar to Type 2 Diabetes in humans, meaning that it’s affected by both genetic and environmental factors.

As a result, the type and quantity of food given to your cat is a primary part of their treatment plan. For many diabetic cats, making adjustments to bring their diet more in line with biological needs can result in worthwhile reductions in insulin requirements—or even remission.

The latest studies on the relationship between diet and diabetes in both cats and humans suggest that insulin independence is a realistic goal when diet and insulin supplementation are given attention. When cats receive a high protein, low carbohydrate diet (as well as appropriate home blood glucose monitoring) symptoms can be dramatically improved. Some studies report diabetes remission rates exceeding 60 percent in cats receiving a combination of pharmacological and dietary treatment.

So, while it can be hard to completely avoid carbohydrates and other undesirables in today’s cat food options, it’s worth taking the time sort those foods with quality ingredients from the brands pedaling fillers and sub-par components. It’s also a good idea to have a comprehensive conversation about diet your vet, as not every cat with diabetes will benefit from the same nutritional profile.

Let’s look at the food types that do and don’t contribute to effective insulin management in cats, and which Diabetic Cat Foods make the grade for 2020.

What should a cat with diabetes be eating?

Choosing the right food products for your cat

Nutritional needs for cats with diabetes


The feline species are classed as obligate carnivores, meaning that they only source nutrition from live prey and meat products. There’s some dispute about how accurate this classification is for house cats, but even if they are able to partly derive energy from carbohydrates, cats should never be consuming carbs as a significant part of their diet.

This is even more true for diabetic cats, who may have developed the condition through a carbohydrate-rich diet in the first place. Cats with diabetes should steer clear of:

  • Dried foods
  • Foods containing gravies or sauces (with tend to be very carb-heavy)
  • Process treats
  • Foods where a carbohydrate is listed in the top five ingredients (e.g. grain or cornmeal)

As you may have noticed, most pet food brands choose not to display carbohydrate content as part of the nutritional information label. The ethics of this aside, it’s not too difficult to work out the numbers for yourself, especially if the other nutrients are listed as percentages. Simply add together the protein, fat, fiber, moisture, and ash, and subtract that number from 100.

Note: there are a minority of situations where cats with secondary and related health issues, such as kidney disease, may not respond well to a low carbohydrate diet. Always seek guidance from your vet when it comes to medical aspects of diet.


A diet that’s rich in well-sourced proteins is a real and validated method of controlling diabetes symptoms and insulin levels in many cats. There have been several studies on the merits of a controlled high protein diet for cats with diabetes. In a 2001 paper, cats eating a high-protein, low-carbohydrate canned diet for three months experienced improvements in insulin levels, to the extent that insulin injections were completely stopped in three of the cats.

In cat food, the difference between good and bad protein can be subtle. While dried food or products made with so-called ‘meat-meal’ be able to claim a higher protein concentration, real meat sourced from whole animal products usually offers a more favorable nutritional profile. Try to only choose from foods that list a whole protein as the top (or even top three) ingredients.


The nutritional profile of cat food should always read protein, fats, carbohydrates, in that descending order. Cats love fats, as they source the majority of their energy from them (rather than carbs). But we need to be careful in managing the fat intake of cats with diabetes, as high levels can easily add unwanted calories to their diet, exacerbating symptoms.

Again, look for whole animal fats on the ingredients label, and follow recommendations from your vet concerning the exact amount of fat your cat should be eating. With some cats liable to lose significant weight due to diabetes, there’s a need for individual consultation and treatment.

Fiber and supplements

Most cat foods developed specifically for pets with diabetes display recommendations or certifications from nutritionists, researchers, and vets. While owners should always do there own research (starting with a careful read of the ingredients label) this can provide some assurance that food is well-balanced.

Fiber is technically a carbohydrate, but as it can’t be broken down in the same way, including some soluble and insoluble fiber in a cat’s diet can help increase blood-sugar stability and aid healthy digestion. As well as being low in sugars itself, fiber encourages slower digestion and a slower release of sugars into the body.

This is an over the counter product – it does not require a prescription.

Vetasyl is also useful in managing diabetic dogs and cats because increasing the amount of dietary fiber helps promote weight loss and slows glucose absorption from the intestinal tract, thereby reducing the postprandial (post-eating) fluctuations in blood glucose. By reducing these fluctuations, better control of hyperglycemia (elevated blood sugar levels) is achieved.

Dosage and Administration: For dogs and cats weighing over 7 lbs., sprinkle one (1) capsule per day on the food. For dogs and cats under 7 lbs., use one-half (1/2) capsule (250 mg) per day. A veterinarian may give specific directions. Follow professional advice closely.

There are no reported side effects. For veterinary use only. For best results, an ample supply of water should be available.

Precaution(s): Store at room temperature.

Caution(s): Keep out of the reach of children.

Active Ingredient(s): VETASYL™ contains psyllium husks 95%, barley malt extract powder (flavor) 5%, acacia and thiamine HCl (vitamin B1). Vetsyl Fiber Capsules are 100% natural. They are formulated without the use of preservatives, artificial flavors, or colors.

Guaranteed analysis: 5% minimum non-crude fiber.


On a like note with humans, cats can have either type I or type II diabetes. Type I is insulin dependent because the body is not capable of producing insulin. Type II diabetes occurs when either the body can’t produce enough insulin or the organs have become insulin-resistant. Cats (especially older and overweight cats) are most likely to acquire what resembles Type II diabetes in humans.

If your cat is diagnosed with diabetes, the symptoms can have harmful effects. If left untreated, diabetes can be life-threatening and dangerous. Potential health implications include bacterial infection, hypoglycemia, liver disease and an unhealthy coat. 

But don’t panic, a feline diabetes diagnosis is not an all or nothing outcome! In fact, caring for a feline with diabetes is more than manageable. Diet is one of the more important, but easier tweaks in managing healthy blood sugar levels. Most cats have Type II diabetes; in these cases food control and weight management are essential in taking care of the disease, and in some cases reducing the symptoms.

If you regularly check with your vet and keep up the right diet, activity level, rest and any medications – then your feline friend can manage their diabetes and maintain a full and happy life.

If your cat is insulin-dependent, it’s important to coordinate their meals along with their insulin dose. To avoid hypoglycemia, you can administer the dose right after they eat so they can digest the calories within a peak insulin time frame.

Furthermore, it might be a good idea to get into the habit of keeping a routine of feeding two to three meals a day rather than leaving a bowl of food out for your cat to graze on during the day. This is because free feeding could cause too many blood sugar spikes. However, in alignment with your cat’s specific condition and needs, some smaller, low carb snacks might be okay during the day.

You should always check with your vet to confirm a diabetes diagnosis if you notice the following signs and symptoms:

  • Increased urination
  • Increased appetite 
  • Dramatic weight loss 
  • Intense thirst 
  • Weakness or lethargy
  • Nausea 

Different cats can show different signs of diabetes, so don’t expect to see all of these symptoms in your cat. However, common signs a cat has diabetes include increased thirst and urination, dramatic weight loss, increased hunger, vomiting, collapsing, and weakness or decreased activity.

Diabetic cats need a high protein, low carbohydrate diet. Therefore wet, canned food is the best food to be feeding your cat. Already formulated with high concentrations of water and protein, wet food will provide the essential nutrient components that a diabetic cat needs.

Controlling diabetes will vary in every case, but in terms of catching on to the disease –  the earlier, the better! Most cats with Type II diabetes will need to have insulin shots and all cats with Type I diabetes will need it. However, blood glucose levels can be controlled with a healthy, nutritionally balanced high-protein/low carb diet in addition to insulin injections or specific prescribed medications.

While there is no cure for feline diabetes, it is treatable. Your furry friend can live with a normal life expectancy as long as you feed the right diet and stick to your vet’s recommended treatment plan. Rest assured that if treated properly, diabetes isn’t a life-limiting illness in cats.
