What's actually in Meow Mix?
We analyzed Meow Mix Original Choice, the brand's flagship product and one of the best-selling cat foods in the country. The first five ingredients are ground yellow corn, corn gluten meal, chicken by-product meal, soybean meal, and beef tallow (preserved with mixed tocopherols).
Ground yellow corn at number one means this is fundamentally a corn-based food, not a meat-based food. Cats are obligate carnivores — they require animal protein to survive and have virtually no biological need for corn. Corn gluten meal at number two doubles down on the corn, serving as a cheap plant protein concentrate that inflates the protein percentage on the label. When the first two ingredients are both corn derivatives, you're looking at a food that is more grain than anything else.
Chicken by-product meal at number three is the first animal-derived ingredient, but it's a rendered product made from the parts of chickens not fit for human consumption — organs, necks, feet, and undeveloped eggs. Soybean meal at number four is yet another plant protein, and it's a common allergen in cats. Beef tallow at number five provides fat but no meaningful protein.
Further down the list, animal digest is a palatability enhancer — a spray or powder made by chemically or enzymatically breaking down unspecified animal tissues. The word "animal" rather than a named species (chicken, beef, fish) means the source can vary from batch to batch. Turkey by-product meal, salmon meal, and ocean fish meal provide some additional animal protein, but they appear so far down the ingredient list that they're present in minimal quantities.

The good stuff
Meow Mix does include taurine supplementation, which is essential for cats — without it, cats develop serious heart and eye problems. DL-methionine is an amino acid that supports urinary tract health. Brewers dried yeast provides B vitamins and may support skin and coat health. The beef tallow is preserved with mixed tocopherols (vitamin E) rather than artificial preservatives like BHA or BHT, which is a small positive.
That's essentially the entire list of positives. Meow Mix meets AAFCO minimum standards for complete and balanced nutrition, so it won't cause an immediate nutritional deficiency on paper. But meeting the bare minimum for survival is a remarkably low bar for a product you're feeding your cat every single day.
The not-so-good stuff
The artificial colors are the most indefensible ingredient in this formula. Red 40, Yellow 5, and Blue 2 are synthetic dyes added to make the kibble pieces look like different flavors — some "meaty" red, some "cheesy" yellow, some "fishy" blue. Cats cannot perceive these color differences. The dyes exist entirely to market to humans, and all three have been linked to behavioral issues and potential health concerns in research studies. There is zero nutritional reason for artificial coloring in cat food.
The double-corn foundation is the structural problem. Ground yellow corn plus corn gluten meal means corn is by far the most abundant component in this food. For an obligate carnivore that evolved to eat whole prey animals, a corn-based diet is a biological mismatch. The protein percentage on the bag might look adequate, but a significant portion of that protein comes from corn gluten meal and soybean meal — plant proteins that lack the complete amino acid profile cats need.
Animal digest as a named ingredient is a transparency red flag. It means the base ingredients are so unappetizing that a flavor-enhancing spray is needed to convince cats to eat the food. When a manufacturer uses unspecified "animal" digest rather than naming the species, it signals a formula that prioritizes cost over consistency.
How it compares
Meow Mix's F/18 puts it near the very bottom of our cat food database, just above Friskies (D/37). These two brands have nearly identical ingredient lists — which makes sense, as both are manufactured by the J.M. Smucker Company. The primary difference is that Friskies adds a fourth artificial color (Yellow 6).
The gap between Meow Mix and even a mediocre cat food is enormous. Purina ONE (D/52) scores nearly three times higher and is available at the same stores. Iams (C/62) scores more than three times higher. Blue Buffalo (B/76) and Taste of the Wild (B/76) are in an entirely different category of ingredient quality. Even Royal Canin (D/45), which we don't consider a good value, is a massive upgrade from Meow Mix.
The price difference between Meow Mix and a genuinely better option like Purina ONE or Iams is often less than $5 per bag. The upgrade in ingredient quality is dramatic for a very small increase in cost.

The bottom line
Meow Mix Original Choice earns an F grade (18/100) from KibbleIQ. A corn-first formula with double corn in the top two positions, three artificial colors, multiple by-product meals, vague animal digest, and soybean meal adds up to one of the worst cat foods on the market. The catchy jingle and decades of brand recognition don't change what's in the bag. If your cat is eating Meow Mix, switching to almost any other brand — even a modestly-priced option like Iams or Purina Pro Plan — will be a significant improvement in every measurable way.
