What Is the Best Food for Diabetic Cats?

Diet plays an important role in diabetes management – your pet might or might not need medication, but in either case, you will have to change the type of food they eat. A lot of readily available dry foods for cats on the market are, unfortunately, chock full of fillers – mostly meat industry by-products whose nutritional value is next to none and grains that are the last thing a diabetic cat needs in their diet. Needless to say, you will have to read quite a few labels before you find a formula suited for the very specific needs of diabetic cats.

The first rule of diabetic cat food is that it should be high in protein and low in carbohydrates. Food that is rich in carbs causes sudden spikes in blood sugar (glucose) and requires more insulin from the body, exacerbating your pet’s diabetic issues (if not causing them in the first place). On the other hand, protein stabilizes blood sugar and makes your cat feel fuller for a longer period of time. Go for high protein formulas that have 10% or fewer carbs in the mix and at least 40% protein content from quality meat, ideally organic when possible. The higher the protein content, the better – after all, cats are obligate carnivores and meat is the only thing their ancestors ate.

Another important factor is the fat content. While healthy fats won’t harm your pet, they do up the caloric value of food, which can be a problem as most diabetic cats need to lose weight or maintain it – and too many fats in their food can cause weight gain. If your pet is struggling with obesity, be sure to choose diabetic cat food with less than 40% fat content.

After you’ve found the right formula for your diabetic cat’s needs, you still need to pay attention to one thing and that’s the portion size. Stick to the recommended serving sizes if your cat is maintaining a healthy weight, but if they need to shed a pound or a few, you’ll have to consult a veterinarian about adjusting portions in a way that promotes healthy weight loss. Obese cats should lose around 1% of their body mass on a weekly level – weight management will greatly help with the management of the symptoms.

If you are unsure which diabetic cat food will work best for your pet, ask your veterinarian. Some kitties have multiple issues (e.g. diabetes and digestive issues, diabetes and urinary infections, or diabetes and lackluster coat), and finding the perfect formula to meet all of their unique needs isn’t always easy. That’s why you’ll need a help of an expert that knows your cat’s medical history – only a veterinarian can ensure your pet is getting the best care they could possibly get.
