Royal Canin Sterilized 37 dry food for sterilized cats has been successfully sold in pet stores for a long time. Its composition has already changed several times, and not for the better. Unfortunately, some veterinarians boldly recommend this product to cats after spaying and neutering, without even looking at the list of ingredients. They are probably guided by brand recognition, the description of the food on its official website and the name of the formula itself.
We decided to find out what the recipe for this popular product actually consists of, and how justified such popularity is. We will try to highlight all the pros and cons of the composition of Royal Canin 37 - if the review of the diet seems too superficial to you, and the evaluation and rating of the food is too low, you can additionally read about each of its ingredients by clicking on the name in the list.
Where is Royal Canin made?
The main enterprises are located in France, one of the subsidiary plants is in the Moscow region (Russia). Russian biscuits and canned food from Royal Canin for sterilized cats are considered to be of lower quality, since the requirements for their production in the country are lower than in the European Union, so owners prefer to feed their pets with French canned food.
Royal Canin is the most popular brand on the market
For your information! The remaining enterprises are located in different countries, but their products are not imported to the Russian Federation. The products are manufactured by Brazilian, Argentine, Canadian, American, South African and British factories.

Is Royal Canin food suitable for all cats?
The compatibility of Royal Canin food depends on its variety. Medicinal products are only suitable for unhealthy animals. In the absence of diseases, food can provoke metabolic disorders and the development of pathologies. The daily diet is suitable for all healthy cats. Giving this food to sick pets is prohibited due to its poor composition.
Due to the wide range, everyone can choose a compatible product. However, it is not recommended to use Royal Canin preventive or daily ready-made diets for regular feeding due to the unsuitable balance of proteins, fats and carbohydrates for cats.
Recommended daily feeding allowance

- Pouch (100 g) for cats with digestive disorders costs 60–80 rubles.
Opinion of veterinarians and animal owners
There are various reviews about the company's products, and they are not always positive. The difference in opinion is related to the quality of the product, the structure and the attitude of pets to the proposed diet.
Some veterinarians claim that Royal Canin is more suitable for animals with health problems, and for absolutely healthy animals it lacks animal proteins.
Important! Incorrect use of the therapeutic line provokes disruption of the functionality of internal organs; before taking it, you should consult a veterinarian.
Makarov Andrey Yurievich, veterinarian, Samara:
“Good biscuits and canned food made from quality ingredients, but not all of them are suitable for cats. I consider the disadvantage to be the inclusion of plant proteins, which are poorly digestible, 30% worse than animal proteins. Biscuits and canned food are balanced, but due to soybean oil and cereals they are not very healthy or nutritious. The main advantage of Royal Canin is its line of medicinal products, which are produced for cats of different ages and breeds. The milk replacer for kittens is also of good quality; babies raised on it subsequently do not lag behind their peers.”
All veterinarians praise this brand of milk for kittens
Svetlana, 45 years old, Vologda:
“I buy Royal Canin all the time, my cat is completely satisfied with it. Fresh food is prohibited here. Marquise is completely fed and feels good, she has no digestive problems, and her coat is always thick and shiny. The advantages of using it include availability (can be bought at any large store), a large assortment for animals of any age, and good quality. The disadvantages are the high price and included flavors, preservatives, soy, grains, gluten and by-products.”
For your information! If you wish, you can choose between French and Russian Royal Canin products. Both plants operate according to the same standards, but the habit of considering foreign plants to be the best among Russians is difficult to eradicate.
Review of Royal Canin food
was founded in 1967 in France. Currently, production is carried out in several countries, including Russia. In 2002, the company was purchased by Mars Corporation and joined the Masterfoods division.
The Mars company also produces economy-class products: Whiskas, Kitekat, Chappie and others. The corporation specializes in the production of inexpensive food up to super-premium class.
Most of the food from the daily line is premium. Such products are not used for regular nutrition due to the low content of animal proteins. Cats are predators, so an excess of grains can cause them allergies, deterioration in the quality of their coat, metabolic disorders and a number of diseases of the gastrointestinal tract and urinary system.

Medicinal feeds mainly belong to the super-premium class. They can be included in the diet on an ongoing basis, but this should be done with caution and only after consulting a veterinarian. The balance of nutrients and additional ingredients are selected taking into account the characteristics and needs of unhealthy animals, so in a pet without pathologies, the product may cause a deficiency or excess of certain compounds. This will lead to the development of diseases. Often medicinal feeds are used in courses due to the characteristics of the composition and course of pathologies.
The key advantages of Royal Canin products are a wide range and an individual approach. The company produces many types of food for representatives of various breeds and age categories. When choosing ingredients and their proportions, the pets’ lifestyle is taken into account, which helps to avoid exhaustion or obesity. Depending on the breed, the company may include additives to improve the condition of the coat, improve joint health, prevent allergic reactions, etc.
A visual comparison of Royal Canin with other foods for spayed and neutered animals
Cat owners note that Royal Canin allows their pets to feel good, but its component structure leaves much to be desired. The price and quality indicators of the product do not correspond to each other; for the same money you can find cheaper and higher quality options.
Statements are not always confirmed by practice; some advertised types are no better than Royal Canin products. For comparison, you can consider several well-known brands produced for castrated and sterilized animals:
| Name | Price | What does it consist of? | Opinion |
| Royal Canin Sterilized 37 | 600 rub. |
| Not ideal, but not the worst option either. The cost is inflated due to advertising and popularity. |
| Whiskas with chicken | 200 rub. |
| The first place is occupied by wheat flour, which is unacceptable for carnivores. The type of most ingredients is not specified by the manufacturer; the share of meat products is minimal. |
| Josera Leger | 450 rub. |
| Good nutrition due to the use of several types of meat - the first 5 positions are allocated to components of animal origin. The overall impression is spoiled by hydrolyzed protein, but it is compensated by the cost ratio and quality indicators. |
| Grandorf Adult Sterilized 4 Meat & Brown Rice Living Probiotics | 750 rub. |
| It is well balanced and contains special preventive additives. Of all the options listed, its composition is closer to the natural diet of cats. Brown rice spoils the impression, despite the use of a specific variety and whole grains. |
It cannot be said that Royal Canin products are as dangerous for animals as competing companies say. It is safe, since a product with questionable quality characteristics is not allowed on the market; it undergoes mandatory tests before release. The company's opponents forget to compare the cost of fresh meat and ready-made canned goods and biscuits. Veterinarians advise paying attention to the cat’s condition and behavior; only by these signs can one determine whether food from a particular manufacturer’s line is suitable for it.

Wheat and other grains
Ingredient number 3 - wheat. Note that this is the most undesirable grain for cats of all grains, and it is a shame that it was included in the food, especially in the first five ingredients. Ingredient No. 4 is grain flour, another nebulous component that can be obtained from a mixture of absolutely any waste from flour milling.
By the way, in addition to these two cereal components, we also found rice in the composition, but we assume that it is quite small, since in the list of ingredients it is closer to additives. Finally, ingredient No. 5 is plant fiber, a food “ballast” of unknown origin that cats do not need at all.
Based on the first five, it is clear that the food does not contain a single, let alone fresh, or even raw meat or fish ingredient, but there are a lot of grains.
