The information is current and up-to-date in accordance with the latest veterinarian research.

Diabetes is becoming one of the most common illnesses globally, not just in people but also in cats. With more cats developing diabetes than ever, pet parents are left scouring reviews and wondering what the best way to handle their cats’ diabetes is.

Weight management and diet are the best ways to get control over diabetes. Your cat needs to be fed a diet appropriate for its needs. Food high in protein and low in carbohydrates is the best option for cats, especially in the case of cats with diabetes, since protein causes fewer spikes in blood sugar levels.

While prescription diets can be fed, they’re not necessarily required for cats with diabetes; any food with high-quality protein content and low in carbohydrates can be used for cats with diabetes. However, if your diabetic cat is already on insulin treatment, it is very likely that after switching to a low-carbohydrate diet your cat will require less insulin or in many cases any at all. It is very important to monitor your cat’s blood glucose right after switching to a low-carbohydrate diet and to make insulin dose adjustments as required.

Having a cat that’s diagnosed with diabetes can be especially frustrating. But the good news is that this disease can be managed very well and even brought into remission with the right diet plan and daily exercise. Just like humans, cats don’t want to deal with syringes and have to take insulin shots just to manage their blood sugar levels every day.

This can be exhausting and tiring for the cat, and it can take a toll on you as its owner. So, if you do have a feline that has recently been diagnosed with diabetes know that there are ways that you can help mitigate this disease right at home. One of the best ways that you can do this is to provide it with the proper nutrition.

Small cat food can help you with this. One of the first signs of diabetes in cats is thirstiness and an increase in appetite. All Smalls cat food is human-grade and contains a sufficient amount of moisture to help improve your cat’s daily hydration levels.

They have different minced and pate meat mixtures to give your cat. Their human-grade cat food is satiating and full of nutrients that will give your cat all of the vitamins and minerals that it needs to get through the day. The only downsides to this food are that it is a subscription service, and the food isn’t available in stores.

Buyer’s Guide: Finding The Best Diabetic Cat Foods

When buying food to assist with a health problem, you must understand the inner workings of the issue. This knowledge allows you to best select products that will help control the issue. Understanding the exact organs and systems that diabetes effects can help you choose the right food for your needs.

What Is Feline Diabetes?

Most cases of feline diabetes are similar to the issues of Type 2 Diabetes in humans. In cats with diabetes, the body’s cells no longer respond adequately to insulin, the compound that allows sugar to enter the cells and be used as fuel and broken down into other necessary compounds.

The pancreas creates more insulin to compensate for this deficiency, but this added stress eventually wears the pancreas out, and the organ fails. Once the pancreas has failed, the cat will need insulin shots or oral insulin regulators to control its blood glucose levels.

Left untreated, the body is unable to function correctly as it has no way of regulating blood glucose levels.

What Factors Contribute to Feline Diabetes?

Obesity is one of the biggest factors in feline diabetes. Cats are very lazy by nature, and the unfortunate side effect of indoor cat care is that they no longer need to hunt for food, and they are at significant risk of becoming overweight.

If your cat has diabetes, controlling its weight is going to be the biggest mitigating factor. Fat cells produce hormones that make the body less sensitive to insulin. By controlling or lowering your cat’s weight, and limiting the carbohydrate content in their diet, you can put their diabetes into remission. However, it is very important to remember to lower your cat’s weight slowly and to adjust the insulin treatment with your cat’s vet accordingly, as a cat on a low carbohydrate diet might stop needing insulin eventually. Blood glucose measurements and treatment adjustments need to be implemented when you change your diabetic cat’s diet.

Achieving Remission

By controlling or lowering your cat’s weight, you can put its diabetes into remission. Remission is achieved when a cat maintains a stable glucose level over four weeks without needing insulin shots or oral insulin regulators.

Not all cats go into remission, but those that do can stay there for several years or even the rest of their lives. Some studies state that between 17% and 67% of cats go into remission after insulin therapy, and others posit that remission is possible for at least 90% of cases.

What Makes a Food Diabetic Friendly?

Diabetic-friendly foods are high in proteins and low in carbohydrates and sugars. Carbohydrates and sugars cause spikes in blood sugar levels that can overwhelm the pancreas and the body and send the cat into diabetic shock.

While many veterinary diets claim to be specially formulated for diabetic cats, any low-carb/high-quality protein food, when fed in moderation, will be acceptable for your cat. Before making any decision, make sure you consult your veterinarian, as they’ll be able to help guide you to the correct food choices and help you portion out foods based on your cat’s insulin therapy.

Veterinarians also recommend feeding your diabetic cat wet food only. Dry foods have a more extensive carbohydrate content than wet foods, some of which contain no carbohydrates at all. While dry food can be made with low carbohydrate content, wet foods are better on average for a diabetic cat.

Feeding a Diabetic Cat

Diabetic cats should be fed on a set schedule. They’ll get insulin therapy twice a day, twelve hours apart, and their meals should coincide with their therapy schedule. You’ll want to feed your cats right before you give your diabetic cat their insulin so that the diabetic cat gets the most out of its insulin therapy. Again, regularly monitoring your cat’s blood glucose and making treatment adjustments is extremely important in the management of diabetic cats, especially after a change to a low-carb diet.

If you have more than one cat, you’ll need to feed them separately to avoid food stealing, and you won’t be able to free-feed your other cats anymore. Adjusting all of your cats to a feeding schedule can be difficult, but it will be the best for the health of your diabetic cat.

Treats given to a diabetic cat should be limited if given at all. Treats need to make up 10% or less of your cat’s diet because they can interfere with the feeding schedule. Good options for treats for a diabetic cat are freeze-dried chicken, beef, salmon, tuna, and liver. These treats are high in protein and contain little if any, carbohydrates.

Final Thoughts

There are lots of options available for pet parents of diabetic cats. For the best product overall, we recommend Smalls Human-Grade Fresh Cat Food. For those who need better-budget food, Purina Pro Plan offers excellent value for the price.

No matter what food you choose, remember to consult with your veterinarian so that they can build a comprehensive meal plan to keep your cat healthy!
