What is Diabetic Cat Food?

Diabetic cat food is special pet food formulated for the needs of cats with diabetes mellitus.

There are two feline diabetes types – type 1 and type 2. In type 1 diabetes, the cat’s pancreas does not produce enough insulin, while in type 2 diabetes, the pancreas makes insulin, but the cells are unresponsive (insulin resistance).

Insulin is the hormone that allows sugar (glucose) to be taken by the cells and used. When insulin is malfunctioning, the result is hyperglycemia or high blood sugar levels. In cats, type 2 diabetes is much more common than type 1.

Diabetic cat food is an important part of diabetes management. Proper diet is combined with the mainstream treatment – insulin therapy, given once or twice a day, based on the cat’s needs.

What Makes Diabetic Cat Food Different?

Diabetic cat food is different on two levels.

First, diabetic cat food is low in carbohydrates, thus preventing unnecessary blood sugar spikes. Second, it has moderate calories, which helps with weight management – cats with diabetes are prone to weight gain and obesity. Interestingly, overweight cats are also more likely to develop diabetes in the first place.

Diabetic cat food is still rich in high-quality proteins, which cats, as obligate carnivores, need. If it contains grains or other carbohydrate sources, they are easily digestible and with low glycemic indexes (unlikely to increase the blood sugar levels).

Diabetic cat food contains all the necessary nutrients (vitamins, minerals, fatty acids, amino acids, and other micronutrients) that the cat needs for optimal growth, maintenance, and performance.

Is Wet or Dry Food Better for Diabetic Cats?

Wet cat food is a much better option for diabetic cats.

Canned food does not affect blood glucose levels much as it has a lower carbohydrate content. Plus, compared to dry cat food, wet formulas are higher in moisture, thus supporting hydration.

Healthy hydration is vital for diabetic cats. Water helps prevent urinary tract infections – an issue that is very common in cats with diabetes.

However, not all wet cat foods are equally good for diabetic cats. For example, canned foods in pate style are better than pouches with a lot of gravy. This is because gravies tend to be high in sugars.

What Should I Look for in a Diabetic Cat Food?

The low carbohydrate content is the main consideration when looking for diabetic cat food. Here is a close look at the important factors to consider:

  • Low Carb to High Protein Ratio. If your cat eats food that is rich in carbs, it can lead to a sudden spike in blood sugar levels. This increases the demand for insulin which is exactly the opposite of what a diabetic cat needs. Foods with low carbohydrates negate this response and cats should be getting most of their calories from protein. Therefore look for foods that offer 50% of the calories from protein, 40% from fats, and 10% from carbohydrates. Carbohydrate levels are not often listed on pet food labels, but they are relatively easy to calculate.
  • Wet vs. Dry Options. Kibble usually contains more carbohydrates than wet food. Canned food contains low concentrations of carbs or no carbs at all. However, there are also some low-carb diets in dry form. If you are not sure whether to use dry or wet, talk to a nutritionist, or ask the vet to prescribe a veterinary diet.
  • Over-the-Counter vs. Prescription. Many low carbohydrate/high-protein foods are available over-the-counter. However, others are prescription diets and need to be approved by a vet.
  • Flavor and Texture. Since diabetic cats have several limitations to their foods, it is crucial that their food tastes good and that they look forward to what they have to eat. Canned foods are overall tasty and perfect for diabetic cats.

After choosing the best diabetic cat food, it is vital to pay attention to portion sizes. This is because managing the cat’s weight help with diabetes treatment.

What Ingredients Should Not be in a Diabetic Cat Food?

If you are to maintain your cat’s overall health and wellness, there are some ingredients that should be avoided:

  • Corn Meal and Carbohydrate Fillers. These are not just rich in carbs; they are also used to just add bulk to the cat food – totally not recommended.
  • Sugars. It is not difficult to explain why sugar is to be avoided for diabetic cats. Sugar is not a natural food for cats and will cause blood sugar spikes, thus harming diabetic cats.
  • Grains. Grains are difficult to digest for cats and can lead to several health problems. They also contain a significant amount of carbohydrates.
  • BHT, BHA, and Ethoxyquin. These are basically preservatives that are used in pet foods. They are not only difficult to digest, but they also have cancer-causing properties.
  • Meat Byproducts. These are secondary products made in addition to the principal product. Often, the source of the meat is not disclosed and can be harmful to your cat.
  • Alkaline Products. These are potentially harmful products that lead to urinary tract infections and kidney stones that can deteriorate your cat’s health.

How Often Should I Feed My Diabetic Cat?

Diabetic cats should be fed twice a day. Pet owners should give two meals daily and administer the insulin injection about 30 minutes after the meal.

Insulin injections are critical as the cat’s blood glucose levels will naturally spike following meals. The amount of insulin your cat needs depends on its weight and diabetes severity. The insulin dosage will be determined by your vet.

When managing diabetic cats, consistency is the key – they need to be given meals at the same time of the day, every day. If adding storebought or homemade treats to the diabetic cat’s diet, their calories need to be extracted from the daily food intake.
