10 Best Foods for Diabetic Cats in 2020

Over 30 million people in the United States have diabetes – that’s nearly 10% of the country’s population. Of those, only 23 million people have been diagnosed, leaving about 7 million people undiagnosed. Spurred in part by the obesity epidemic, diabetes has become a serious problem in people, and it has even started to become more common in pets.

It is estimated that between 0.2% and 1% of cats in the general population suffer from diabetes. As is true for people, cats can develop two different types of diabetes. Type II is the most common form, though Type I does happen from time to time. Unfortunately, the symptoms of diabetes are sometimes easy to miss which leads to delayed diagnosis. In severe cases, undiagnosed and untreated diabetes in cats can lead to a worsening of symptoms.

In this article, we’ll explore the subject of feline diabetes in greater depth to learn what it is, what causes it, and how it can be treated and managed. You’ll also receive some advice for feeding a diabetic cat and see our low carb cat food list to help you pick the best cat food for diabetes.

Feline diabetes or diabetes mellitus is a condition in which the body either fails to product enough insulin or has a diminished response to insulin. Insulin is a hormone secreted by the body after eating that allows the cells and tissues on the body to absorb glucose from the blood stream to use it as energy. In a way, the insulin “unlocks” the doors to the cells, allowing them to absorb glucose. As blood sugar levels rise, so should insulin levels. As the glucose is absorbed from the blood stream, those blood sugar and glucose levels drop back down to normal.

In a cat with diabetes, there are problems with this process. Cats with Type I diabetes fail to produce enough insulin which means that blood sugar levels remain elevated. Cats with Type II diabetes don’t respond properly to insulin which keeps blood sugar levels high. Type II diabetes is the most common form in cats and both types have similar symptoms.

Here are some of the most common symptoms of feline diabetes:

  • Urinating more frequently
  • Unexplained weight loss
  • Excessive thirst
  • Overweight or obesity
  • Muscle wasting in the back
  • Increased hunger
  • Lethargy
  • Nerve problems, changes in gait

Though diabetes in cats may not seem like a serious problem, it can lead to complications if left untreated. Chronically elevated blood sugar levels can be damaging to the body and may lead to nerve damage (called neuropathy) that might affect the cat’s muscles and his ability to walk. Risk factors such as obesity, increasing age, and low activity levels can worsen these symptoms. In mild cases, however, feline diabetes can be transient. Prompt treatment is insulin injections, healthy weight loss, and changes in diet can resolve the issue and prevent it from becoming a long-term disease.

Now that you understand the basics about feline diabetes, you may be wondering which is the best treatment for your cat. In the next section, we’ll talk about options for diabetes treatment and management and we’ll explore how changing your cat’s diet might help.

How is Feline Diabetes Managed?

The good news about feline diabetes is that there are treatment options and it can be managed. It is important to remember, however, that while diabetes isn’t a death sentence, it isn’t something you should ignore. With proper treatment and management, you could resolve your cat’s diabetes in a year or two. Without treatment, however, your cat’s condition could worsen, and he may develop secondary health problems that could shorten his lifespan and affect his quality of life.

The best treatment for feline diabetes will vary depending how early the condition is diagnosed and which type of diabetes your cat has. The sooner you notice symptoms and report them to your doctor, the sooner he can make a diagnosis and start your cat on insulin treatments. Short-term insulin injections can prevent long-term damage to your cat’s pancreas which might make the condition permanent. Even with prompt treatment, however, your cat will require close veterinary monitoring with frequent blood tests to check his glucose and insulin levels.

In addition to making sure your cat gets the veterinary care he requires, you may also need to make dietary changes to help manage his condition. When it comes to dietary management of diabetes, you need to remember your cat’s basic nutritional requirements, first and foremost. Cats are obligate carnivores which means they have a biological need for protein in their diets. Ideally, 50% of their daily calories should come form protein and 20% to 45% from fat. Only 1% to 2% of your cat’s daily calories should come from carbohydrates, so you may want to familiarize yourself with a low carb cat food list. Aside from that, high moisture levels can also be beneficial for diabetic cats.

What to Look for in a Good Cat Food for Diabetic Cats

When it comes to feeding your diabetic cat, you have two options: a prescription diet or a non-prescription food for diabetic cats. If your cat’s condition is severe and he needs to gain or lose a significant amount of weight, you may want to consider a prescription diet. It might be the best way to ensure that he gets the nutrition he needs to support his recovery. Just make sure that you evaluate the food yourself to determine whether it is a high-quality product.

If you decide on a non-prescription food for diabetic cats, you’ll find that you have a wide variety of options to choose from. Your cat’s basic nutritional requirements come first, but there are some additional things to look for in the best food for diabetic cats.

Here are some of the things we look for in a good cat food feline diabetes: 

  • Real animal proteins. All cats require a high level of protein in their diets and it is best from animal sources like meat, poultry, and fish. Animal proteins are more digestible and biologically valuable for your cat, so make sure they are the first ingredient in any recipe you choose.
  • Moderate healthy fat content. Fat provides a concentrated source of calories for cats as well as essential fatty acids. If your cat is obese or overweight, you want to control the fat content of his diet to control the calories. Just remember that cats do require some fat, ideally from animal sources, to ensure a balanced diet with essential fatty acids like omega-3s and omega-6s.
  • Low carbohydrate content. A low-carb diet is recommended particularly for diabetic cats, though all cats have a limited ability to digest carbohydrate ingredients. Aim for no more than 10% of your cat’s calories to come from carbohydrates because a high-carb diet will elevate your cat’s blood sugar levels and make his diabetes more difficult to manage.
  • Highly digestible ingredients. The more digestible your cat’s diet is, the better. High-quality, natural ingredients are more digestible and fresh foods like whole grains and vegetables have a lesser impact on your cat’s blood sugar levels.
  • No artificial additives. Artificial colors, flavors, and preservatives have no place in your cat’s diet. Avoid anything that contains low-quality grains like corn, wheat, and soy which can cause spikes in blood sugar. You should also avoid by-products and artificial additives.
  • Higher moisture content. Increased moisture content in cat food makes it more digestible. Plus, cats with diabetes tend to need higher amounts of moisture in their diet. Look for a low carb canned food for diabetic cats if you want to meet his needs for moisture.

Now that you’ve learned what your cat needs in terms of diet, you may be looking for a low carb cat food list to get you started in your search. We’ve compiled a collection of our top picks for the best wet cat food and best dry cat food for diabetic cats below.

How Do We Make Our Recommendations?

Balanced nutrition is essential for all cats, not just cats with diabetes. It is important to remember that cats have a biological requirement for high levels of protein in their diets with moderate amounts of fat and low carbohydrate content. In addition to checking the nutritional levels in every cat food we recommend, we also take a look at the ingredients to ensure that the sources for those key nutrients are nutritious and of high quality. We would never recommend a cat food that we wouldn’t feel comfortable feeding our own pets, so rest easy!

Here are some of the requirements for a cat food to receive our recommendation: 

  • A source of high-quality animal protein as the first ingredient
  • At least 30% crude protein for kittens and at least 26% for adults
  • A minimum of 9% crude fat for kittens and adults
  • A balance of omega-3 and omega-6 fatty acids, primarily from animal sources
  • A rich blend of nutrients from natural sources and supplements, as needed
  • Limited carbohydrate content from digestible sources (like whole grains and veggies)
  • No low-quality fillers, by-products, or artificial additives (preservatives, dyes, or flavors)
All of our cat food recommendations are made based, first and foremost, on AAFCO food nutrient profiles. These profiles simply outline the minimum nutritional needs of cats in various life stages (kitten or adult). In order to determine whether a cat food meets these requirements, just look for an AAFCO statement of nutritional adequacy on the package. It should look something like this: [X Product] is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for all life stages. After you have successfully determined that the formula is complete and balanced, you can go on to evaluating its quality.

Frequently Asked Questions

  1. What is the best food for a diabetic cat? The best food for a diabetic cat is one that meets his basic nutritional requirements while helping him manage his diabetes. This means a high-protein diet with moderate fat content and low carbohydrate content. There are many different cat foods that meet these requirements, so you will be able to shop around and find one that also meets your cat’s dietary preferences.
  2. How many times a day do you feed a diabetic cat? When it comes to managing feline diabetes, the goal is to keep your cat’s blood sugar levels as stable as possible. When your cat eats, you can expect his blood sugar to rise, so it is important to time his meals to coincide with his insulin injections. In most cases, diabetic cats do well with two meals per day. You should try to feed the same amount of food on the same schedule every day for the best results.
  3. Should diabetic cats eat dry food? Dry food is the preferred option for many cat owners, but it may not be the best choice for diabetic cats. Cats with diabetes require a higher level of moisture in their diet and dry food tends to only have about 10% moisture. A canned food diet contains somewhere between 78% and 82%, so it is worth considering making the switch for your cat.
  4. Is grain free cat food good for diabetic cats? Generally speaking, grains are a nutritious source of carbohydrates and essential nutrients for cats. Grain allergies are not as common as some pet food manufacturers would have you believe, so it is really only necessary to feed your cat a grain free diet if he has a confirmed allergy or sensitivity. When it comes to diabetic cats, however, things may be slightly different. Grains like corn, wheat, and soy will have a significant impact on your cat’s blood sugar levels while whole grains like brown rice, oatmeal, and barley have a lesser effect (as long as they are unrefined). Vegetables are also less likely to significantly impact blood sugar than fillers. Whether you feed your cat a grain free diet is up to you, but be sure the carbohydrates in your cat’s food are highly digestible and have a low glycemic impact.
  5. How do cats get diabetes? For some cats, diabetes is a condition they inherit. Type I diabetes is characterized by the cat’s inability to produce enough insulin which is typically an issue that involves problems with the pancreas. With Type II diabetes, the cat has trouble utilizing insulin properly. This too can be related to issues with the pancreas but can also be related to obesity and other underlying health problems. To determine the underlying cause of your cat’s diabetes, you should talk to your veterinarian.

Feline diabetes is a very manageable condition, but that doesn’t make it insignificant. In many cats, diabetes is related to obesity and obesity can increase your cat’s risk for a variety of other serious health problems. No matter what type of diabetes your cat has and how he got it, it is your responsibility to seek veterinary care and to properly manage the condition.

Feeding your cat the right diet can help, so take what you’ve learned here to choose the best food for diabetes in cats. If you’re not sure where to start your search, simply try one of the options we’ve recommended above! Good luck!
