5 Best Canned Food for Diabetic Cats

Before diving into the list, let’s understand why a high-protein, low-carb diet is essential for diabetic cats. Cats are obligate carnivores, meaning their bodies are best adapted to a diet high in animal protein. Carbohydrates, on the other hand, can spike a cat’s blood sugar levels, leading to increased insulin requirements. Therefore, a diet high in protein and low in carbs can help manage diabetes and potentially even lead to remission in some cases.

1. The Purina Pro Plan Veterinary Diets DM Dietetic Management

Purina Pro Plan Veterinary Diets DM Dietetic Management is a standout in the realm of diabetic cat foods. Its impressive high-protein, low-carb formula is scientifically designed to aid in managing diabetes, which is reflected in its first ingredient: real chicken. This means that your feline friend is getting a significant portion of its protein from a high-quality, easily digestible source.

Moreover, the food’s texture is specially crafted to appeal to feline preferences, which encourages regular consumption and aids in consistent nutritional intake. A unique feature of this diet is the inclusion of essential vitamins and minerals, which not only aids in maintaining overall health but also supports your cat’s immune system, making it an excellent choice for managing diabetes.

2. Royal Canin Glycobalance

The Royal Canin Glycobalance cat food, another prescription diet, is well-known for its nutritionally balanced formula. This diet’s primary protein source is chicken, a lean and easily digestible meat that helps to maintain muscle mass while managing blood glucose levels.

One defining characteristic of the Royal Canin Glycobalance diet is its attention to urinary health. Since diabetic cats are often prone to urinary issues, this added feature can be a crucial factor in overall health management. It has a relative supersaturation (RSS) methodology, which reduces the concentration of ions contributing to struvite and calcium oxalate crystal formation, thus aiding in urinary health.

3. Fancy Feast Classic Pate

Despite not being exclusively marketed for diabetic cats, the Fancy Feast Classic Pate line often comes recommended by both veterinarians and pet parents dealing with feline diabetes. The reason? Its high-protein, low-carb formula closely aligns with the dietary needs of diabetic cats.

A highlight of the Fancy Feast Classic Pate line is its variety. With several flavors available, including chicken, turkey, beef, and fish, this line keeps mealtime exciting for your cat, promoting regular consumption and ensuring consistent dietary management.

4. Merrick Backcountry Grain-Free Wet Cat Food

The Merrick Backcountry Grain-Free Wet Cat Food series shines due to its high-quality protein sources and grain-free formula. Diabetic cats often benefit from a grain-free diet, which keeps carbohydrate levels low. This particular line showcases real meat (chicken, beef, or turkey) as its primary ingredient.

Beyond its primary benefit as a protein-rich, low-carb diet, this series also includes omega-3 fatty acids, supporting skin health and promoting a glossy coat – a delightful bonus in the world of diabetic cat management.

5. Orijen Cat & Kitten Grain-Free Dry Cat Food

Although not canned, it’s important to mention a high-quality dry food option, particularly for those felines who might not be fans of wet food. The Orijen Cat & Kitten Grain-Free Dry Cat Food stands out for its impressive nutritional profile, which includes an array of protein sources such as turkey, chicken, and fish.

This food offers a freeze-dried liver infusion to increase palatability, thereby encouraging regular eating. Furthermore, Orijen’s biologically appropriate philosophy means this food is formulated to mirror the quantity, freshness, and variety of meats that cats are evolved to eat, providing an excellent choice for diabetic cats.


Why is Low-Carb, High-Protein Important for Diabetic Cats?

Feline diabetes, much like human diabetes, is characterized by the inability to regulate blood sugar levels. This is largely due to inadequate insulin production or ineffective use of insulin by the body. Cats, being obligate carnivores, naturally consume diets high in protein and low in carbohydrates. A diet that follows this natural pattern, being high in protein and low in carbohydrates, aligns with their metabolic needs, helping to regulate blood glucose levels effectively and manage diabetes.

Why is Wet Food Better than Dry Food for Diabetic Cats?

The moisture content in wet food is significantly higher than in dry food, which helps to keep your cat hydrated. Good hydration can aid in the prevention of urinary tract issues, which are often a concurrent problem in diabetic cats. Furthermore, wet food generally has higher protein content and fewer carbohydrates than dry food, making it a superior choice for diabetic cats.

Can Diabetic Cats Eat Dry Food?

While wet food is typically recommended for diabetic cats due to its lower carbohydrate content, some high-quality dry foods, like the Orijen Cat & Kitten Grain-Free Dry Cat Food, are formulated to be high in protein and low in carbs. If your cat is used to dry food or prefers it, consult with your veterinarian about suitable options. However, it’s crucial to ensure that your cat has access to plenty of fresh water, especially when feeding a primarily dry diet.

Can Diabetic Cats Eat Tuna?

While it might be tempting to serve your cat a diet primarily made up of tuna or other fish, it’s not recommended as a complete diet for a few reasons. Firstly, an exclusive tuna diet may lead to nutritional deficiencies as it doesn’t provide all the nutrients that cats require. Secondly, too much fish in a cat’s diet can lead to health issues like mercury poisoning. However, as part of a balanced diet and served in moderation, tuna can be an acceptable part of a diabetic cat’s diet, provided it’s low in sodium and not packed in sugary or oily sauces.

Can Diabetic Cats Eat Non-Prescription Food?

Yes, diabetic cats can eat non-prescription food. However, the food should be high in protein, low in carbohydrates, and ideally wet food. Some commercial non-prescription cat foods like Fancy Feast Classic Pate meet these dietary requirements. Always consult with your veterinarian before switching your diabetic cat’s diet.

How to Transition Your Cat to a Diabetic-Friendly Diet?

Transitioning your cat to a new diet should be done gradually to avoid gastrointestinal upset. Start by mixing a small amount of the new food into your cat’s current diet. Over a week or two, gradually increase the new food’s proportion while decreasing the old food’s until your cat is fully transitioned. If your cat is resistant to the new food, warming it slightly or adding a bit of flavor with a low-sodium broth may help. Always observe your cat during dietary transitions for any changes in behavior, appetite, or litter box habits and consult your vet with any concerns.

What Treats are Suitable for Diabetic Cats?

Treats for diabetic cats should be low in carbohydrates and high in protein. Some options include freeze-dried meats or fish, which are typically high in protein and low in carbs. For instance, PureBites Freeze-Dried Cat Treats are a good choice, as they are made from a single ingredient like chicken or turkey. However, treats should be given sparingly and should not constitute more than 10% of your cat’s daily caloric intake. Always consult your veterinarian for the most appropriate treat options for your diabetic cat.

How Often Should a Diabetic Cat Eat?

Feeding frequency can play a crucial role in managing your cat’s diabetes. Diabetic cats often benefit from multiple small meals throughout the day, rather than one or two large meals. This helps to balance the blood sugar levels and prevent peaks and troughs. Typically, feeding your cat three to four times per day is recommended.

What Role Does Insulin Play in a Diabetic Cat’s Diet?

Insulin is essential for regulating blood sugar levels. In diabetic cats, insulin therapy is often required in conjunction with dietary management. The type and timing of food can impact how your cat’s body responds to insulin. For example, feeding your cat a high-protein, low-carb diet can help to maintain more stable blood glucose levels, allowing the insulin to work more effectively.

What Should I Do if My Diabetic Cat Refuses to Eat?

If your diabetic cat refuses to eat their prescribed diet, it’s crucial to consult with your vet promptly. Your vet can suggest alternative food options, or they might recommend using appetite stimulants. Prolonged periods without food can lead to a serious condition called hepatic lipidosis in cats, which can be life-threatening. In some instances, it’s more important to get your cat eating again (even if it’s not their diabetic-specific food) than to strictly adhere to the prescribed diet.

Can a Diabetic Cat’s Diet Affect Its Need for Insulin?

Yes, a diabetic cat’s diet can impact its insulin requirements. A diet high in protein and low in carbohydrates can help control blood sugar levels and, in some cases, may reduce the amount of insulin your cat needs. In fact, some cats, when switched to a low-carb diet, have been known to go into diabetic remission and no longer require insulin. However, any changes to insulin dosage should be made under the direct guidance of a vet.

Is Exercise Important for Diabetic Cats?

Exercise can play a beneficial role in managing feline diabetes as it helps to increase insulin sensitivity and control weight. Regular play sessions using toys, laser pointers, or even a simple piece of string can provide much-needed physical activity. If your cat enjoys the outdoors, supervised outside time or walks using a cat harness can also provide exercise. It’s essential to aim for consistent exercise levels daily, as sudden increases in activity can cause hypoglycemia in diabetic cats. As always, it’s best to discuss your cat’s exercise routine with your vet.
