Royal Canin Regular STERILISED 37 Adult Cat Sterilization Formula is a scientifically tailored dry food designed specifically for neutered adult cats. After sterilization, cats face unique health challenges, including a slowed metabolism and increased risks of weight gain and urinary issues. This premium Royal Canin cat food directly addresses these concerns with a precise nutritional profile. Its core benefits include effective weight management through moderate fat and added L-carnitine, robust urinary system protection via balanced minerals, and crucial muscle mass maintenance supported by a high 37% protein content. Trusted by veterinarians and made in France, it provides complete, targeted nutrition for sterilized felines aged 1 to 7 years, promoting long-term vitality and an ideal body condition.
Royal Canin STERILISED 37 Product Features & Benefits
Royal Canin STERILISED 37 cat food is engineered with a multi-faceted approach to post-sterilization health. The formula's design is rooted in understanding the physiological changes that occur after a cat is spayed or neutered, primarily a reduction in energy requirements and hormonal shifts. This specialized Royal Canin formula offers three interconnected core benefits that work synergistically to support overall well-being.
First, the formula promotes precise weight control. It contains a moderate fat level of 12.0%, which helps manage calorie intake without sacrificing energy. Crucially, it is fortified with 100mg/kg of L-carnitine, a nutrient that acts as a shuttle, transporting fatty acids into the mitochondria where they are burned for energy. This process enhances fat metabolism, helping sterilized cats utilize their fat stores more efficiently and reducing the risk of obesity, a prevalent post-operative concern.
Second, it provides essential urinary system protection. Neutered cats have a known predisposition to urinary tract issues, including the formation of struvite and calcium oxalate crystals. Royal Canin STERILISED 37 supports urinary health through a meticulously balanced mineral profile, with controlled levels of calcium (0.88%) and phosphorus (0.80%). This balance helps maintain an optimal urinary pH and promotes dilute urine, creating an environment less conducive to crystal formation and supporting long-term urinary tract integrity.
Third, the formula is dedicated to muscle mass maintenance. Despite managing calories for weight control, it delivers a high 37% protein content from quality sources like dehydrated poultry protein. Nutritionists suggest that high-protein diets are vital for sterilized cats to preserve lean muscle tissue during weight loss or maintenance. Maintaining muscle is critical for sustaining a healthy metabolic rate, supporting mobility, and ensuring your cat remains firm and active.
Key Nutritional Ingredients in Royal Canin Cat Food
The efficacy of Royal Canin STERILISED 37 stems from its carefully selected and balanced ingredients, each serving a specific functional purpose for sterilized cats. This is not a generic recipe but a targeted nutritional strategy developed by Royal Canin's veterinary nutritionists.
The primary protein source is dehydrated poultry protein, providing highly digestible, high-quality amino acids essential for muscle maintenance and overall health. Animal fats supply a concentrated source of energy, while corn and vegetable protein isolate contribute to the formula's balanced nutrient matrix. For digestive support, the food includes fructooligosaccharides (FOS), prebiotics that nourish beneficial gut bacteria, and beet pulp, a source of fermentable fiber that aids in healthy digestion and stool quality.
Beyond these foundational ingredients, specific functional additives set this formula apart. Fish oil is included as a rich source of EPA and DHA, essential fatty acids that support skin health and provide anti-inflammatory benefits. The star nutrient, L-carnitine, is added at 100mg/kg specifically to enhance fat burning. Experts recommend L-carnitine in weight management diets as it helps the body convert fat into usable energy, making weight loss more efficient and helping to maintain an ideal body condition score.
Why Choose Royal Canin for Your Sterilized Cat's Health
Choosing Royal Canin STERILISED 37 is an investment in preventative, science-backed healthcare for your neutered companion. Royal Canin distinguishes itself through decades of research and collaboration with veterinarians, breeders, and nutritionists. Their breed-specific and life-stage-specific formulas are the result of this deep expertise, moving beyond one-size-fits-all pet nutrition.
This particular formula exemplifies the Royal Canin approach: identifying a specific health need—post-sterilization metabolism—and creating a precise nutritional solution. The brand's commitment is evident in the targeted levels of key nutrients. For instance, the exact 37% protein level is calculated to meet the increased protein demands of a cat in a calorie-controlled state, while the specific mineral ratios are designed to directly influence urinary pH. This level of precision is often lacking in standard adult maintenance foods.
Furthermore, Royal Canin maintains stringent quality control, manufacturing this food in its own facilities in France. This ensures consistency and safety in every 2kg bag or larger package you purchase. For pet owners, the value lies in the peace of mind that comes from feeding a diet formulated by leaders in veterinary nutrition, potentially reducing the risk of costly health issues like obesity-related diabetes, arthritis, or urinary blockages down the line.
Royal Canin STERILISED 37 vs. Regular Adult Cat Food
Understanding the difference between a specialized sterilization formula like Royal Canin STERILISED 37 and regular adult cat food is key to making an informed feeding choice. The distinction is significant and directly impacts your cat's long-term health.
Regular adult cat food is designed as a maintenance diet for intact, generally healthy cats with normal activity levels. Its nutrient profile is broad, aiming to support overall health without targeting specific physiological conditions. In contrast, Royal Canin STERILISED 37 is a therapeutic nutrition formula tailored to the altered internal environment of a neutered cat. The most critical differences are in calorie density, functional additives, and mineral balance.
Regular food often has a higher fat and calorie content to meet the energy needs of active, intact cats. Feeding this to a sterilized cat with a reduced metabolic rate can quickly lead to weight gain. Royal Canin's formula has moderate fat and added L-carnitine specifically to counteract this. Similarly, regular food does not prioritize urinary mineral balance, whereas STERILISED 37 carefully controls calcium and phosphorus levels to protect the urinary tract. Finally, while protein is important in all diets, the emphasis on a high 37% protein level in STERILISED 37 is a direct strategy to combat muscle loss during weight management, a focus not typically present in standard maintenance diets.
Target Audience and Feeding Guidelines for Royal Canin Formula
Royal Canin STERILISED 37 is specifically formulated for sterilized (spayed or neutered) adult cats between 1 and 7 years of age. It is a complete diet intended for long-term daily feeding to manage weight and support urinary health. It is not suitable for kittens, pregnant or nursing queens, senior cats over 7, or highly active, intact adult cats, as their nutritional requirements differ.
Proper feeding is crucial to realizing the benefits of this specialized Royal Canin cat food. The daily portion depends on your cat's ideal weight, not its current weight if it is overweight. Always refer to the precise feeding guide on the product packaging, which provides weight-based recommendations. As a general principle, divide the total daily amount into two measured meals. Use a proper measuring cup for accuracy, as estimating can lead to overfeeding.
Monitoring your cat's body condition is an ongoing process. Weigh your cat monthly and perform a hands-on assessment: you should be able to easily feel its ribs with a slight fat covering, see a visible waist when viewed from above, and observe an abdominal tuck from the side. Adjust the portion size up or down in small increments based on these observations. Always ensure unlimited access to fresh, clean water, especially when feeding dry kibble, to support hydration and urinary health.
How to Successfully Transition to Royal Canin STERILISED 37
A gradual transition over 7 to 10 days is essential when switching your cat to Royal Canin STERILISED 37 to prevent gastrointestinal upset like diarrhea or vomiting. Abrupt dietary changes can disrupt the delicate balance of gut bacteria.
Start by mixing 25% of the new STERILISED 37 kibble with 75% of your cat's current food. Feed this blend for 2-3 days while closely observing your cat's appetite and stool consistency. If all is well, move to a 50/50 mix for another 2-3 days. Then, increase the proportion to 75% new food and 25% old food for a further 2-3 days. Finally, you can complete the switch to 100% Royal Canin STERILISED 37.
Throughout this process, patience is key. Some cats may be hesitant due to the new shape, size, or aroma of the kibble. Persist with the mixed portions; their taste preferences will typically adapt. If you notice soft stools, slow the transition by spending an extra day or two at the current mixing ratio. This method allows your cat's digestive system to gradually acclimate to the different nutrient and fiber profile of this targeted sterilization formula.
