The Best Diabetic Cat Foods

A diabetes diagnosis for your cat doesn’t need to be a disaster. With the correct diet and medication implemented shortly after diagnosis, your cat’s diabetes could effectively be reversed (in the case of type 2 diabetes), meaning she can be weaned off her insulin shots. Choosing a proper diabetic cat food for your feline friend is the first step. Diabetic cat food should be high in protein and very low in carbohydrates (less than 10% and even under 5% is best in some cases). In theory, fat content can be moderate, but you may want to start out with a low fat option if your cat needs to lose weight. Although there are foods on the market specifically designed for diabetic cats, you’ll find some standard high protein cat food fits the bill, too.

We reviewed dozens of diabetic cat foods to identify the best of the best. We compared nutritional values, flavor, value for money, and average customer reviews to find the best options out there.

Our Top Pick: Hill’s Prescription Diet GlucoSupport Cat Food

Hill’s Prescription Diet GlucoSupport Cat Food is our first choice of diabetic cat food for a number of reasons. Formulated by both veterinarians and nutritionists, this cat food is clinically tested to support your diabetic cat in two major ways: managing their glucose levels as well as their weight. What’s more, it’s clinically proven to reduce body fat.

This diabetic cat food is packed full of ultra-nutritious ingredients that aid your cat’s digestion, and even boasts essential amino acids and antioxidants. It’s high in protein and low in carbohydrates, which represents an ideal balance for diabetic cats.

At $54.99 for an 8.5-pound bag, it doesn’t come cheap. But it’s worth keeping in mind that you’ll get what you pay for, as this is without a doubt one the highest-quality diabetic cat foods available. Plus, you may not need to use it long term. Once your cat has lost weight and her blood sugar is more stable, you may be able to switch to a standard high protein, low carb cat food.

Hill’s Prescription Diet GlucoSupport Cat Food Key Features:

  • Veterinary grade formula
  • Manages your cat’s blood glucose levels
  • Includes essential amino acids and antioxidants

NomNomNow Flavorful Fish Feast

Check Price

And now for something slightly different. NomNomNow provides a cat food delivery subscription tailored to your cat’s dietary needs. When you sign up, you enter details about your cat’s size, weight, medical conditions, and dietary requirements, and the company tailors portion sizes and feeding schedules to meet the needs of your feline friend.

NomNomNow makes two wet cat food recipes, both of which are suited to diabetic cats. The Chicken Chow-Meow gets 56% of its calories from protein and 10% from carbohydrates, while the Flavorful Fish Feast gets 50% of calories from protein and just 5% from carbohydrates. If your diabetic cat thrives on low carbs, the fish recipe is a slightly better option, but 10% of calories from carbohydrates still makes the chicken recipe a low-carb option.

According to NomNomNow, it costs roughly $14 per week to feed an average 7-pound cat on its food, which is very reasonable considering the quality. That said, it may cost more depending on your cat’s portion sizes.

Purina Veterinary Diets DM Dietetic Management Dry Cat Food
If you choose to feed your diabetic cat dry kibble, this glucose management formula is a fair bet.

Dry food isn’t always the best option for diabetic cats, as carbohydrate content is often too high. Purina Veterinary Diets DM Dietetic Management Dry Cat Food, however, is specifically formulated for diabetic cats and does an excellent job of regulating glucose levels. The high protein content releases energy slowly, which helps to prevent spikes and crashes of blood sugar that often occur after eating and can be especially problematic for cats with diabetes. This formula also contains plenty of ingredients that may help to boost your cat’s overall health, such as antioxidants and omega-3 and omega-6 fatty acids.

Many cat owners who reviewed it stated that they’ve been very pleased with how effective it has been in helping their cats to lose weight and control their glucose levels. The only downside we found with Purina Veterinary Diets DM Dietetic Management Dry Cat Food is that you’ll need your vet’s approval to buy it. While this sounds complicated, it’s actually straightforward once your vet gives it their A-OK. All you need to do is provide some basic details about your pet and vet at the checkout. Priced at around $32 for a 6-pound bag, it’s not exactly affordable, but it’s about on par price-wise with other similar veterinary-grade diabetic cat food.

Purina Veterinary Diets DM Dietetic Management Dry Cat Food Key Features:

  • Contains omega-3 and omega-6 fatty acids
  • Great taste most cats love
  • Liver as the first ingredient

Who Should Buy Diabetic Cat Food?

If your feline friend has been diagnosed with diabetes, it’s essential that you buy diabetic cat food. The combination of high protein and low carbohydrates helps to prevent spikes in blood sugar, which can be hugely detrimental to cats with diabetes. Cat food suited to diabetic cats also tends to be low in calories, since the majority of diabetic cats are overweight. Even if it isn’t listed as diabetic cat food, if the levels of nutrients are correct, it will still fit the bill.

Important Features to Consider

Diabetic cat food should have a few important features. Here’s what to consider when selecting a cat food for your diabetic cat:

  • Wet vs. dry. As a rule, wet food is better for diabetic cats than dry food, before it tends to contain more meat, and less grains and starches, meaning is has higher protein and lower carbs than dry food. What’s more, the high moisture content is great for cats who don’t drink enough water (though this can sometimes be improved through the use of cat water fountains, which can encourage some cats to drink more). However, there are some instances in which it’s just not possible to feed wet food, such as in an automatic cat feeder or for cats who will only free feed rather than eating a full meal in one go.
  • Protein content. It can be tricky to compare the protein content in wet and dry cat foods, since the listed content on wet foods isn’t adjusted to reflect the fact that they contain far more moisture than dry foods (75 to 85% in wet food vs. 6 to 10% in dry food). There are ways of converting these figures to a dry matter basis, but all you really need to know is that the protein content of diabetic wet cat food should be at least 10%, whereas dry food should be at least 40%.
  • Carbohydrate content. Carbohydrate content generally isn’t listed on cat food packages, as it isn’t required by law, but you can figure it out by adding up the percentages of protein, fiber, ash, and moisture, then subtracting this number from 100. Whatever’s left is the carbohydrate percentage. This should definitely be less than 10% for diabetic cats, and ideally less than 5%.
  • Calories. There’s no recommended calorie level for diabetic cats, nor does diabetes alone mean your kitty needs to eat a low calorie diet. However, many diabetic cats are also overweight and weight loss can help to improve type 2 diabetes in cats. As such, you may choose to feed a low calorie food to your diabetic cat until she’s reached her ideal body weight.
  • Recipe. The flavor, or “recipe”, doesn’t necessarily make a difference to how effective a cat food is at maintaining stable blood glucose levels, but it will affect how palatable your cat finds it. Choose a recipe carefully, with your cat’s likes and dislikes in mind, especially if she’s a fussy eater.

Frequently Asked Questions

How many times a day do you feed a diabetic cat?

Cats on short-acting insulin shots should stick to two to three meals a day, Small, low carb snack in between are okay if necessary, but free feeding would case too many blood sugar spikes.

What are the signs that a cat has diabetes?

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.

Can diabetes in cats be controlled with diet?

All cats with type 1 diabetes and most cats with type 2 diabetes will need to have insulin shots. However, it is sometimes possible for type 2 diabetes (which is the more common form) to be controlled with diet alone, albeit infrequently.

How long can cats live with diabetes?

As long as you feed the correct diet and go along with your vet’s recommended treatment plan, your cat can live to a full life expectancy with diabetes. Treated properly, it isn’t a life-limiting illness in cats.
