Frequently asked questions
Why do vets recommend Purina Pro Plan over premium boutique brands?
Purina invests over $350 million annually in pet nutrition research — more than any other company. Pro Plan formulas are validated through live AAFCO feeding trials (where actual cats eat the food for extended periods) rather than just laboratory nutrient analysis. Boutique brands often rely on formulation software without real-world validation.
Should cats eat wet food, dry food, or both?
Ideally both. Dry food is calorie-dense and convenient. Wet food provides hydration — critically important because cats have a naturally low thirst drive (evolved in the desert) and chronic mild dehydration is a leading cause of urinary tract disease and kidney failure. Aim for at least 30–50% of calories from wet food if feeding a mix.
How much dry cat food should an adult cat eat per day?
Most adult cats (8–10 lbs) need about 1/4 to 1/2 cup of dry food daily, split across 2 meals. But the package feeding guide is a starting point — adjust based on your cat's body condition. At a healthy weight, you should feel your cat's ribs without pressing hard, and see a slight waist when viewed from above.
What makes Purina Pro Plan different from Purina ONE?
Both are made by Purina, but Pro Plan uses higher-quality protein sources, contains live probiotics (backed by clinical research on feline gut health), and meets higher nutritional standards. Purina ONE is a good mid-range option; Pro Plan is Purina's premium line and is the version veterinarians specifically recommend.
Is grain-free cat food better for cats?
No — grain-free cat food provides no proven benefit and carries some risks. Unlike grain-free dog food and DCM, the evidence in cats is less concerning, but cats don't require grain-free diets. Grains like rice are easily digestible by cats and serve as excellent energy sources. The FDA has not flagged grain-free cat food for heart disease concerns.
