Feeding guides are general recommendations only. The amount of food required by your cat may vary above or below that listed in this feeding guide. In consultation with your veterinarian it is recommended that you weigh your cat 4 - 6 weeks after starting a new diet in order to adjust food intake to maintain or achieve an optimal body weight and body condition score. Consult your veterinarian for specific feeding guidelines for your cat. This diet is formulated to be complete and balanced. It is unnecessary to feed leftover foods, kitchen scraps or additional supplements. It is recommended that your cat be fed 2 - 4 equal portions of the diet per day. Ensure fresh drinking water is available at all times. Store this product in a cool, dry place.

Transition Instructions

We recommend at least a 7 day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.


Frequently Asked Questions

How are Royal Canin diets preserved?

All of our dry diets are preserved naturally with mixed tocopherols, citric acid, and rosemary extract. Our canned diets are naturally preserved and sterilized during the cooking and canning process.

Where do the ingredients in Royal Canin diets come from?

We select our ingredients based on multiple factors, including the supplier’s compliance with our quality and food safety requirements, consistent availability, and on the nutrients required to meet the dietary needs of the pet.Royal Canin is making strides towards sustainability by attempting to obtain sources of raw materials as close to each manufacturing facility as possible. In some cases, we use international suppliers, because only those suppliers can offer raw materials that comply with our quality and food safety standards.

Why do some Royal Canin diets contain by-products?

Royal Canin chooses ingredients because they deliver high-quality nutrients that support our customized pet food formulas.

  • Glycobalance

    By on

    I love the service! I have two cats on different prescription diets. My vet's office sells some prescription diets but not glycobalance. I cannot carry the heavy cans and bags of food. So much easier to have it delivered. My cat loves glycobalance. Thank you for getting prescription info. Much Appreciated. Gilda

    I needed this Rx catfood in a hurry when my vet was out of stock. I easily placed the order online, called my vet to give them a heads up about the prescription order request and within two hours of placing the order, I had a shipment confirmation email. The order arrived two days later.

  • For cat with diabetes

    By on

    This was prescribed for our cat with diabetes. Just started her on it so the jury is still out as to its effectiveness but at least she likes. Our other cat seems to prefer it over his old food since he switches to her bowl whenever he gets a chance.

  • Monica loves her new wet/dry food for diabetic felines

    Monica enjoys her new wet and dry Glycobalance cat food. She was diagnosed as diabetic one month ago and is adjusting to her Insulin and new diet. She really seems brighter and energetic as we proceed on regulating her blood sugar levels and anticipate a healthy life for her, going forward.

  • Great for diabetic cats

    By on

    This is a popular choice for our cats. We are so fortunate that our diabetic cat loves it, and his brothers also like it so it can be left out. I only wish it were made in larger bags, like all the other Royal Canin dry foods.
