Purina ONE Sterilcat Salmon is a dry cat food formulated for adult sterilized cats, designed to support their unique metabolic needs and maintain lean body mass.

The first ingredient is salmon, including head, bones, and meat, which provides a natural source of high-quality animal protein and essential fatty acids to support muscle maintenance and skin health.

With a crude protein content of 37% and fat at 13%, the formula offers a high-protein, moderate-fat profile that helps maintain lean muscle while supporting energy needs in sterilized cats, who are prone to weight gain.

Dehydrated poultry and fish proteins further enhance the amino acid profile, contributing to tissue repair and overall vitality.

Chicory root and beet pulp serve as prebiotic fiber sources, promoting digestive health and supporting beneficial gut bacteria.

The inclusion of heat-treated Lactobacillus delbrueckii and Lactobacillus fermentum provides probiotic support, which may help stabilize intestinal flora and improve nutrient absorption.

Essential vitamins such as vitamin A (36,960 IU/kg), vitamin E (460 IU/kg), and vitamin C (140 mg/kg) contribute to immune function, antioxidant defense, and cellular health.

Omega-6 fatty acids at 2% support skin barrier function and coat condition, which is especially important for indoor cats exposed to dry environments.

Balanced mineral levels, including calcium and phosphorus both at 1.2%, help maintain bone health and support urinary tract function.

The metabolizable energy of 3,632 kcal/kg provides a controlled energy density suitable for weight maintenance in less active or neutered cats.

Pros:

• High protein content: At 37%, the formula supports lean muscle mass and overall metabolic health in sterilized adult cats.

• Digestive support with prebiotics and probiotics: Beet pulp, chicory root, and heat-treated Lactobacillus strains promote gut health and nutrient absorption.

• Rich in essential vitamins: High levels of vitamins A, E, and C contribute to immune defense and antioxidant protection.

• Balanced mineral profile: Calcium and phosphorus at 1.2% each help maintain bone strength and support urinary health.

• Omega-6 fatty acids: At 2%, they help maintain healthy skin and a shiny coat, especially beneficial for indoor cats.

Cons:

• High carbohydrate content: At 28.5%, the formula may not be ideal for cats requiring lower-carb diets for weight or blood sugar management.

• Use of plant-based fillers: Ingredients like wheat, corn, and soy flour contribute to the carbohydrate load and may not suit cats with grain sensitivities.

• Moderate ash level: At 7.5%, the ash content may be a concern for cats with kidney or urinary sensitivities.

• Low taurine content: At 780 mg/kg, taurine is present but lower than levels often targeted for optimal heart and eye health in adult cats.
