15 Best Cat Foods For Diabetic Cats In 2024

Diabetes is becoming one of the most common diseases in the world, not only in humans but also in cats.

With more cats developing diabetes than ever before, pet parents are left perusing reviews and asking how to effectively manage their cats' diabetes.

Diabetes can be effectively managed by weight management and diet. Your cat requires a diet tailored to its specific requirements.

Food strong in protein and low in carbohydrates is the best option for cats, especially diabetic cats, because protein causes less blood sugar increases.

While prescription diets can be offered, they are not always necessary for diabetic cats; any meal with a high protein content and low carbohydrate content can be fed to diabetic cats.

If your diabetic cat is already on insulin, switching to a low carbohydrate diet will most likely result in your cat requiring less insulin, if any at all.

It is critical to monitor your cat's blood glucose levels immediately after switching to a reduced carbohydrate diet and modify insulin doses as needed.

BestForPets (bestforpets.org) has compiled a list of the best cat foods for diabetic cats currently available.

Finding the Best Diabetic Cat Foods: A Buyer's Guide

When purchasing food to help with a health concern, you must first understand how the problem works. This knowledge enables you to select the appropriate products to help control the problem.

Understanding the specific organs and systems that diabetes affects will assist you in selecting the best meal for their needs.

What Exactly Is Feline Diabetes?

The majority of feline diabetes situations are identical to Type 2 Diabetes concerns in people.

Diabetes causes the body’s cells to no longer respond properly to insulin, the chemical that permits sugar to enter cells and be used as fuel as well as broken down into other important compounds.

To compensate for this shortage, the pancreas produces more insulin, but this additional stress eventually wears the pancreas out, and the organ fails.

Once the pancreas fails, the cat will require insulin shots or oral insulin regulators to keep its blood glucose levels under control.

Without treatment, the body is unable to operate properly because it lacks the ability to regulate blood glucose levels.

What Factors Influence Feline Diabetes?

Obesity is a major contributor to feline diabetes. Cats are naturally lethargic, and an unfortunate side effect of indoor cat care is that they no longer need to search for food, putting them at risk of getting overweight.

Controlling your cat’s weight will be the most important mitigating factor if it has diabetes. Fat cells secrete substances that reduce the body’s sensitivity to insulin.

You can put your cat’s diabetes into remission by regulating or lowering their weight and restricting the carbohydrate amount of their diet.

However, it is critical to remember to gradually reduce your cat’s weight and to adjust insulin treatment with your cat’s veterinarian as needed, as a cat on a low carbohydrate diet may eventually stop requiring insulin.

When changing your diabetic cat’s diet, blood glucose levels and therapy changes must be implemented.

Obtaining Remission

You can put your cat’s diabetes into remission by regulating or lowering their weight.

Remission occurs when a cat maintains a stable glucose level for four weeks without the need for insulin injections or oral insulin regulators.

Not all cats go into remission, but those who do can stay there for years, if not their entire lives.

According to some research, between 17% and 67% of cats achieve remission after insulin therapy, while others claim that remission is feasible in at least 90% of instances.

What Qualifies a Food as Diabetic Friendly?

Diabetic-friendly foods have a high protein content and a low carbohydrate and sugar content.

Carbohydrates and sugars produce blood sugar surges, which can overwhelm the pancreas and throw the cat into diabetic shock.

While several veterinary diets claim to be particularly created for diabetic cats, any low-carb/high-quality protein meal will be fine for your cat if provided in moderation.

Before making any decisions, consult your veterinarian, who will be able to assist you to the right food options and portion out foods according on your cat’s insulin therapy.

Veterinarians also advise feeding your diabetic cat only wet food. Dry foods have more carbs than wet foods, some of which contain no carbohydrates at all.

While dry food can be created with a low carbohydrate content, wet food is generally healthier for diabetic cats.

Diabetic Cat Nutrition

Diabetic cats should be fed on a regular basis. They’ll be given insulin twice a day, twelve hours apart, and their meals will be scheduled to fit with their therapy regimen.

You should feed your cats right before giving your diabetic cat insulin to ensure that the diabetic cat gets the most out of its insulin therapy.

Again, regular blood glucose testing and therapy modifications are critical in the management of diabetic cats, especially after switching to a low-carb diet.

If you have more than one cat, you must feed them individually to minimize food theft, and you will no longer be allowed to free-feed your other cats.

Adjusting all of your cats to a feeding schedule can be challenging, but it is best for your diabetic cat’s health.

If treats are provided to a diabetic cat, they should be limited in quantity. Treats should account for 10% or less of your cat’s diet because they can disrupt the feeding pattern.

Freeze-dried chicken, beef, salmon, tuna, and liver are all good diabetic cat treats. These snacks are high in protein and have little, if any, carbs.


There are numerous solutions accessible to diabetic cat owners.

Canned Hill's Prescription Diet m/d GlucoSupport Cat Food is the greatest overall product. Purina Pro Plan  provides outstanding value for money for people in need of superior budget food.

Whatever food you choose, remember to check with your veterinarian so they can create a comprehensive diet plan for your cat’s health!

Find a natural alternative method to reverse different diseases and STDs no matter what science says about their illness. I am sharing my healing encounter from genital herpes after using Dr Okosun herbs, a herbal doctor from Africa, to cure my HSV-1&2 diagnosis permanently. A few weeks ago my new lab result still shows that I tested negative after being cured since 2018. I am so happy I gave it a try. Currently, my 65 years old mom is using Dr okosun herbs to eliminate her diabetes and the recovery process is amazing. I am recommending this product for those that are willing to give it a try as these holistic remedies do not have any side effects.
