What’s actually in Whiskas?
We analyzed Whiskas Meaty Selections Chicken & Turkey Flavors, a flagship US dry formula from Mars Petcare. The first five ingredients are poultry by-product meal, ground yellow corn, ground wheat, corn gluten meal, and soybean meal — one rendered meat ingredient followed by four plant and grain ingredients.
Poultry by-product meal at number one is an unnamed rendered meal — “poultry” can mean chicken, turkey, or a blend, and by-product means the parts not used for human food. The label markets it as a “natural source of glucosamine and chondroitin,” but it is still a species-generic protein. After it, the next four ingredients are all plant-based: corn and wheat supply starch, while corn gluten meal and soybean meal are concentrated plant proteins that push up the crude-protein percentage on paper without delivering the animal-based amino acids cats actually need. Fat is listed only as generic “animal fat,” another unnamed source, preserved with BHA. Shop on Amazon →
The good stuff
To be fair, Whiskas does a few things right. It includes added taurine, an amino acid that is absolutely essential for cats — without enough of it, cats can develop dilated cardiomyopathy and irreversible retinal damage. Seeing taurine spelled out on the deck is a genuine plus, and DL-methionine supports urinary-tract health. The formula is also rounded out with a full vitamin and chelated-mineral pack.
Like all AAFCO-compliant cat foods, Whiskas is formulated to meet the profile for adult maintenance, so your cat will not develop an outright deficiency on paper. It is also cheap (roughly $1.33 per pound) and sold almost everywhere, and the heavy fat-and-flavor coating makes it palatable enough that most cats will graze on it all day. For a household on a tight budget, availability and acceptance are real, practical advantages — they are just not the same thing as ingredient quality.
The not-so-good stuff
The core problem is the protein. A single unnamed by-product meal is the only meaningful animal ingredient in the entire food, and everything after it is corn, wheat, soy, or supplements. For an obligate carnivore that evolved to eat whole prey, a deck where positions two through five are all plant matter is a biological mismatch. Corn gluten meal and soybean meal inflate the guaranteed-analysis protein number (around 35%) with plant protein, which masks how little of that protein comes from meat.
Then there is the BHA. The fat is preserved with butylated hydroxyanisole, a controversial synthetic antioxidant, and it appears twice on the ingredient list — once in the animal fat and again on its own. Plenty of better foods use natural mixed tocopherols (vitamin E) instead. Combined with the unnamed “animal fat,” the fat sourcing here is as generic as the protein.
Finally, the marketing oversells the meat. “Meaty Selections,” “meaty flavor,” and “two poultry flavors” all imply real chicken and turkey, but there is no whole or named meat anywhere on the deck — the only nod to those birds is “natural chicken and turkey flavor,” a flavoring, not an ingredient with nutritional substance. Reframing a by-product meal as a glucosamine benefit is the same playbook: technically accurate, but it dresses up the cheapest protein in the formula as a feature.
How it compares
Whiskas’ D/44 sits squarely in the grocery-kibble cluster at the bottom of our cat food database. It edges out Friskies (D/39), 9Lives (D/38), and Meow Mix (D/35) — all corn-and-by-product formulas in the same below-average tier. Whiskas scores a little higher mainly because it leans on by-product meal and plant protein rather than artificial dyes, which several of those peers still carry.
The more useful comparison is what a step up looks like. Iams reaches the C tier with named chicken up front, and Fancy Feast (B/75) climbs all the way to a B after a reformulation — proof that even a supermarket brand can do far better than this deck.

The bottom line
Whiskas Meaty Selections Chicken & Turkey Flavors earns a D grade (44/100) from KibbleIQ. An unnamed poultry by-product meal as the sole protein source, a corn-wheat-soy plant-protein base that is poorly suited to an obligate carnivore, generic animal fat, and BHA preservative add up to a textbook grocery formula. Added taurine and the AAFCO-complete profile are what keep it out of the F tier, not the ingredient quality. If your cat is eating Whiskas, it will not come to harm overnight, but almost any named-meat food — even another budget brand like Iams — is a meaningful upgrade in what your cat is actually eating.
