This is a bottom-tier cat food from the world's largest pet food corporation. The primary protein source is unspecified 'Meat By-Products' — a rendering industry ingredient with confirmed pentobarbital contamination risk. Protein is padded with wheat gluten and soy flour instead of actual meat. Two separate corn starch entries are used as fillers. Nestlé Purina makes billions in annual revenue and could easily source named ingredients — but they don't, because Friskies exists to maximize profit, not to feed cats well.

Friskies Prime Filets with Ocean Whitefish & Tuna is what happens when a $100 billion corporation decides to extract maximum profit from cat owners on a budget. The very first protein ingredient is unspecified 'Meat By-Products' — an ingredient that could legally contain euthanized animals, roadkill, and diseased livestock. The protein is then inflated with wheat gluten and soy flour — cheap plant fillers that obligate carnivores cannot efficiently utilize. Two corn starch entries pad the formula further. Menadione (synthetic Vitamin K3) is banned in human supplements but Purina uses it here because it costs pennies. The named fish ingredients — ocean whitefish and tuna — are present, but their position deep in the ingredient list after water, mystery meat, and wheat gluten means they contribute a minority of the actual protein. Nestlé Purina employs board-certified veterinary nutritionists and has massive R&D resources. They know exactly what they're putting in this can. They choose these ingredients because the margin is better, not because they're good for cats. At this price point, there are better options. This food scores an F.
