Royal Canin Cat Food Review

Royal Canin is a brand that invests heavily in nutritional research and safety for their cat foods. They make all of their own foods and perform their own feeding trials in order to ensure the highest standards of safety, quality, and nutrition. Royal Canin does have downsides, however. Recipes are nutritionally sound, but they are highly focused on cost as well. There is a dependence on lower-quality ingredients such as plant proteins, vegetable oils, and pork by-products.

Is Royal Canin a Good Cat Food Brand?

Despite changing ownership numerous times, Royal Canin has maintained a level of independence in making their pet foods. They have their own manufacturing facilities, feeding trial facilities, and nutritionists. They operate nearly as a stand-alone company who focuses heavily on nutrition research and keeping close oversight on safety and quality. In fact, they have not had a recall for over 13 years, nearly unheard of for a brand their size.

Formulas are well tested for digestibility, palatability, long-term health, and urine pH, all essential aspects of any cat food. However, Royal Canin does have lesser quality ingredients compared to many all-natural brands. Their canned formulas rely on plant proteins and pork by-products. Their dry formulas have a fairly low meat content.

As far as legacy pet food brands go, Royal Canin is one of the best. Their track record of safety speaks for itself. Like other brands who carry a veterinary line, Royal Canin has a nutrition consulting service. But unlike their competition, they will speak to average pet owners and veterinarians alike. In our Royal Canin cat foods review, we found out that Royal Canin really has done the work to stand out among other research-focused brands.

Who Makes Royal Canin?

The Royal Canin Company is owned by Mars Petcare.

Royal Canin was founded in France in 1968 by a veterinarian named Jean Cathary. By 1972 the company was sold to a family-run feed business, and Royal Canin quickly expanded across Europe. They were in the US by 1985. In 1990, the parent company was sold to Paribas Bank, who ended up selling Royal Canin to Mars Inc in 2001. To this day Mars remains family owned, with Royal Canin still operating as a separate company under the ownership of Mars Petcare.

Company Know How

Mars Petcare is the biggest pet food company in the world, measured by revenue. Mars itself has a large pet food knowledge base with their staff. Royal Canin operates mostly independently from Mars, running their own pet health nutrition center in Lewisburg Ohio and their own manufacturing facilities too. Cat foods are extensively and humanely tested for aspects such as digestibility, palatability and urine pH. Royal Canin employs a large staff of animal nutritionists, veterinary nutritionists, and food scientists to develop their pet foods. They also have significant production know-how as well. 

Company Values

Mars is a very large, but family-owned, company. Being family owned means that they have greater freedom and do not answer to investment firms or public shareholders. It appears that Mars takes a somewhat hands-off approach to Royal Canin.

Royal Canin’s philosophy is stated simply, “to make a better world for pets.” This can clearly be seen in their nutrition center, which offers large outdoor runs for dogs to play in and state-of-the-art quality of life for their cats and dogs.

Unlike Mars, which has ramped up their research and nutrition expertise in recent years, Royal Canin has been science-minded from the start. They make several veterinary diets using this expertise.

However Royal Canin has had a handful of lawsuits in recent years. Royal Canin, along with other major pet food manufacturers were accused of price fixing in the EU. The whole concept of prescription pet food has also come under legal scrutiny, as there is nothing in the food that actually requires a veterinarian to write a script for. Companies are using the “prescription” system to charge extremely large mark-ups on cat and dog food.

Perhaps the most bizarre thing Royal Canin has done is sponsor bear baiting contests in Ukraine. Apparently this was the decision of a territory sales division. To their credit, Royal Canin took full responsibility and worked closely with the organization that exposed their sponsorship to help fund rescuing the bears.

Production

From the production side, Royal Canin makes all of their food in their company’s own manufacturing plants. Manufacturing locations in the US include Rolla MO, Lebanon TN, and Fremont NE. Doing their own production, and doing so semi-independently of Mars, allows Royal Canin to maintain more strict oversight on their food.

Based on local reviews, there does appear to be some slight variation in quality between facilities, but nothing significantly different. Royal Canin does a good job of understanding their complex supply chains and performing quality control on ingredients.

Royal Canin Recalls

Royal Canin has not had a recall since 2007. The company did have extensive recalls for melamine in their rice protein concentrate. In 2006, Royal Canin also had a recall for excessive vitamin D levels.

Quality

Royal Canin has excellent quality standards. The fact that they manufacture their own food is a huge plus, especially considering they have gone 13 years without a recall. It is rare to see such a good track record in a large legacy pet food brand, and Royal Canin should be applauded for it. They are clearly doing something right.

Puremarket

Puremarket/The Clean Label project has tested hundreds of cat foods for various contaminants, such as lead, mercury and acrylamide. They have tested one Royal Canin wet cat food and seven Royal Canin dry cat foods.

The wet food, Adult Instinctive Loaf in Sauce, received a B+ grade, with slight heavy metal contamination. Dry foods ranged from A- to F in their scores. The charity group found various levels of heavy metal contamination and plasticizers in most foods. They also found pesticides/mycotoxins and process contaminates (likely acrylamide) in some foods as well.

Transparency

The website does not list much in the way of nutrition (they don’t even list phosphorus content), but questions on chewy.com for things like carbohydrate content or phosphorus content are answered. Royal Canin has a nutrition-specific customer service, which was able to promptly answer questions such as copper content in their foods. Royal Canin does a great job with this service, and unlike similar brands, makes it available to both veterinarians and average pet owners.

Other pet owners have had difficulty getting questions about the country of origin for ingredients to be answered. This is likely due to both a simple lack of communication on the part of Royal Canin, as well as extremely complex supply chains they use to make their foods.

What Foods Does Royal Canin Make?

Royal Canin makes a huge number of cat foods, offering about 40 varieties each of wet and dry foods. Recipes are mostly based on breed, age and health concerns. 

Royal Canin’s Wet Food Offerings

About half of the Royal Canin wet cat foods are veterinary prescription diets. This nutritional analysis is of the over the counter diets. All foods come in cans, with no pouches of cups available.

Of the over the counter diets, there are breed and life stage specific formulas. Additionally they have over the counter foods for minor health issues, such as weight loss, hairball care and sensitive stomach. There is almost no variety in protein sources, with all foods containing pork and chicken.

Royal Canin Wet Food Nutrition Review

Ingredients

The wet cat food formulas are made of a combination of pork by-products, pork liver, chicken and chicken liver. In this case, pork by-products include organ meat such as lungs, spleen, brain, kidney etc.

Ideally, it would be better to see each pork ingredient listed separately, but it is much more expensive and may be impossible for Royal Canin to buy various pork organ meat in the quality they need. Oftentimes purchasing an ingredient as “by-products” is the best a large company can do. That being said, the by-products in this food are listed as pork and not “meat,” so it indicates that there is significant care going into the ingredient sourcing.

Many formulas include wheat gluten as an ingredient. This plant protein is a cheap way to increase the protein content of the food, but the amino acid composition is much less useful to cats than a meat protein. It would be preferable to see the protein in this canned food come entirely from meat.

The Royal Canin canned cat formulas are thickened with a variety of ingredients. Formulas use gelatin, pork plasma and cellulose to enhance the texture of the food. Gelatin and pork plasma are great protein-rich texture enhancers, while cellulose provides insoluble fiber.

Vegetable oil is used in the formulas, which is not ideal. This oil is pro-inflammatory and rich in omega-6s. On the bright side, the formulas also include fish oil or salmon in the ingredients to help balance the omega-6 to omega-3 ratio.

Despite canned food not requiring a carbohydrate source, Royal Canin has chosen to add modified corn starch and sometimes wheat flour or rice flour to their wet cat foods. The corn starch is likely to help enhance the texture and palatability of the food, but starches are not nutritionally necessary for cats.

Finally, we see traditional thickeners in the ingredient list. Guar gum and/or carrageenan are soluble fiber sources which help enhance the texture of the food.

The mineral supplement used in the foods is primarily a cheap mineral salt supplement. However, the zinc is chelated, meaning that the zinc is bound to an amino acid and is more readily absorbed by the body.

Nutrients

The average dry matter protein content in Royal Canin’s wet cat foods is around 50%, with a range from 39% to 58%. The average dry matter fat content is 13%, with a range from 6% to 24%.

The dry matter carbohydrate content is around 23% on average, with a range from 16% to 30%. Unfortunately, formulas for senior cats or weight loss are higher in carbohydrates, likely in an attempt to reduce calories. However, overweight cats are prone to diabetes and the most current nutritional thinking is to reduce their carbohydrate content as much as possible.

The average dry matter phosphorus content in the wet cat foods is 1.1%, with a range from 0.5% to 1.6%. This is a reasonably well controlled phosphorus level, and Royal Canin has made an effort to keep senior formulas very low in phosphorus.

Formulas do include fish oil or fish in the ingredients, so it is clear that Royal Canin has provided a source of EPA and DHA omega-3s in every canned recipe. They do not openly publish their omega-3 content of their canned cat food, but it appears that their formulas ensure it is present.

Royal Canin’s Dry Food Offerings

Like the canned foods, about half of Royal Canin’s dry cat formulas are prescription diets. Of the over-the-counter diets, foods are designed for specific breeds, lifestyles, ages and minor health issues.

Royal Canin Dry Food Nutrition Review

Ingredients

The first ingredient in Royal Canin formulas is chicken meal. This is great to see because chicken meal has had the moisture removed, meaning chicken is truly the first ingredient on the list.

After the chicken meal, a number of carbohydrate sources are listed. These include corn, brewers rice and wheat. Considering there are a number of carbohydrate sources, it is likely that overall there are more grains in this food than meat. In addition to grains as a carbohydrate source, corn gluten meal and wheat gluten are also in the ingredients. Glutens are the proteins from these plants. They have a poor amino acid composition compared to meat and are less nutritionally useful to cats. Glutens are a cheap way to increase the protein content of a cat food.

For fiber, the ingredients include pea fiber, rice hulls and/or dried beet pulp. These soluble fiber rich ingredients can help with digestion and help cats feel full between meals.

The fat sources in Royal Canin dry cat foods include chicken fat, vegetable oil and fish oil. Chicken fat and fish oil are great sources, but vegetable oil is rich in omega-6 and is proinflammatory.

Prebiotics are also included in the formulas, including fructooligosaccharides and often psyllium seed husk too. These are great ingredients to promote a healthy gut.

Strangely, some formulas include mineral mixes which are chelates, while others do not. Chelated minerals are the gold standard in supplements, as they are more readily absorbed by the body.

Nutrients

The caloric content of Royal Canin’s dry cat foods is well managed. The majority of the foods sit in the 300 to 350 calories per a cup range. However, weight loss foods sit in the 250 to 300 range. Kitten foods are in the 450 to 500 range. All of this variation shows that Royal Canin has carefully considered calories when formulating their foods.

Protein on average is around 35% on a dry matter basis, with a range from 29% to 44%. Considering that a portion of the protein also comes from glutens, this indicates a relatively low meat content in the dry cat foods. Fat has a wide range, from 9% to 25% on a dry matter basis, with an average content of about 16%. This indicates that the amount of fat has been carefully controlled based on the caloric needs of the diet. Kitten foods are higher in fat while weight loss foods are lower.

The carbohydrate content ranges widely between formulas, 27% to 50% on a dry matter basis. Most foods are in the 25% to 30% range, which is reasonable considering that dry cat foods require a certain amount of carbohydrates in order to maintain their structure.

The average dry matter phosphorus content of the dry cat foods is around 1%. This is a very good level and foods are well controlled ranging from 0.5% to 1.2% phosphorus on a dry matter basis. Phosphorus clearly has been carefully considered in these formulas.

The ingredients list includes fish oil in all of the formulas we considered. Therefore, there is a source of the essential EPA and DHA omega-3s in Royal Canin’s dry formulas. The companies do not publish the exact levels of omega-3s and omega-6s, but it can at least be said that they have been considered.
