If your cat has diabetes or is at serious risk of developing the disease, dietary interventions will be part of your treatment plan. This means you need a diabetic-friendly cat food option, and it's important to discuss diet with your veterinarian before choosing a brand of food. Your vet may recommend removing dry food entirely from your cat's diet as dry food is generally higher in carbs.
Ingredients in Cat Food
Diets for felines with diabetes are primarily high-protein and low in carbohydrates. This means cat food made with quality proteins such as chicken, fish, and beef. Ingredients to avoid include sugar and grains. Supplements such as taurine have also been shown to have a beneficial effect. When looking at food labels for off-the-shelf brands, a guide for the best caloric percentages from VetStreet is:
- 50 percent or more from proteins such as poultry, fish, and beef
- Between 20 and 45 percent from fats
- No more than 2 percent from carbohydrates
- High water content of at least 70 percent of total food weight, which means most off-the-shelf dry foods are not an option
Diabetic Cat Food Options
Your vet will prefer a prescription diet in most cases, but off-the-shelf brands may be an acceptable option depending on your cat's diabetes diagnosis and condition. Discuss your options with your vet to find a food choice you both are comfortable with.

Feeding a Diabetic Cat
Remember when caring for your diabetic or at-risk cat that their nutrition plays an important role in fighting the disease. Many cats may not find all these brands palatable so you may have to experiment to find the one your cat enjoys the most.
