Winner Plus Sterilized Diet is a dry food formulated specifically for sterilized adult cats of all breeds, aiming to support weight control, urinary health, and overall vitality.

The first ingredient, dehydrated chicken, serves as a concentrated and digestible animal protein source that helps maintain lean muscle mass in sterilized cats, whose energy needs are typically lower.

With a high protein content of 36% and a reduced fat level of 11%, the formula is designed to help manage body weight while still supporting essential metabolic functions.

The inclusion of natural vegetable fibers, such as inulin and other plant-based sources, supports digestive health, helps reduce hairball formation, and contributes to better stool quality.

Omega-3 (0.4%) and Omega-6 (2.4%) fatty acids, derived from salmon oil and linseed oil, promote healthy skin and a glossy coat while also supporting anti-inflammatory balance.

Ammonium chloride and a targeted urinary pH of 6.2 help reduce the risk of urinary crystal formation, a common concern in sterilized cats.

L-carnitine (300 mg/kg) is included to support fat metabolism, aiding in the prevention of weight gain and promoting lean body mass.

Functional ingredients like brewer’s yeast and dried egg provide additional B vitamins and high-quality protein, enhancing palatability and nutritional density.

Antioxidants from natural tocopherols and blueberries contribute to cellular protection and immune support.

Taurine (2,000 mg/kg) and DL-methionine (2,500 mg/kg) are added to support heart health, vision, and urinary acidification, which is particularly beneficial for sterilized cats.

Pros:

• High protein, low fat formulation: Supports lean muscle maintenance and weight control in sterilized adult cats with reduced energy needs.

• Urinary health support: Ammonium chloride and a controlled urinary pH of 6.2 help reduce the risk of struvite crystal formation.

• Digestive fiber blend: Inulin and vegetable fibers aid in digestion, reduce hairball formation, and improve stool quality.

• Skin and coat health: Balanced omega-3 and omega-6 fatty acids from salmon oil and linseed oil support a healthy skin barrier and shiny coat.

• Fat metabolism support: L-carnitine promotes efficient fat utilization, helping prevent weight gain in sterilized cats.

• Rich in antioxidants and essential nutrients: Blueberries, vitamin E, and natural tocopherols help protect cells from oxidative stress and support immune function.

Cons:

• Contains multiple grain sources: Ingredients like rice, barley, and corn may not be suitable for cats with grain sensitivities or owners seeking grain-free diets.

• Use of corn gluten: While it contributes protein, it is a plant-based source with lower biological value compared to animal proteins.

• Moderate carbohydrate content: At 32.7%, the carbohydrate level is relatively high for obligate carnivores and may not align with low-carb feeding preferences.

• Unspecified animal protein extract: The use of generic terms like “animal protein extract” lacks transparency and may be a concern for cats with food sensitivities.
