No, and the reason is not what most people assume. It is not that cat food is richer or that dogs would not like it. It is that cats have requirements dogs do not, and a food formulated to a dog standard is not formulated to a cat standard, whatever is in the bag.
Taurine is the usual example. Cats need it supplied in the diet. Stella publishes a taurine minimum of 0.15 percent on their cat kibble and prints it in the guaranteed analysis, and their cat recipes list taurine as an ingredient directly. Dog recipes often include it too, which is part of why the confusion exists. The presence of an ingredient is not the same as a formula built and labeled to a species standard, and the standards themselves are different documents.
If you have both animals in the house, as plenty of our customers at 1288 Highway 33 do, the practical question is usually narrower: can the cat have a bite of the dog's food, or the other way round. A stolen mouthful is not a crisis. A standing arrangement is a different thing.
Where it gets genuinely confusing is that Stella uses similar names across both species, and the products are not equivalent.
Raw Coated Kibble Cage-Free Chicken for cats runs thirty-eight percent protein and sixteen percent fat, with calcium, phosphorus and taurine minimums printed, and 457 kilocalories per cup. The dog version of a similarly named food runs thirty-three percent protein and fourteen percent fat at 435 kilocalories per cup, with glucosamine and chondroitin figures the cat food does not carry. Same brand, nearly the same name on the shelf, different formulas aimed at different animals.
Now the comparison trap, because this one misleads more people than anything else in pet food.
You will see a wet cat food listed at ten percent protein next to a dry food at thirty-eight percent and conclude the dry food has nearly four times the protein. It does not. The wet food is eighty-three percent moisture and the dry is twelve percent. You are mostly comparing water. Guaranteed analysis figures are only comparable between foods with similar moisture, and any comparison that skips that step, including ones made in good faith, produces a number that means nothing.
That matters practically because wet food is where cats get water, and a lot of cats do not drink as much as we would like. Stella's Carnivore Cravings pouches run about ninety kilocalories each and their feeding chart works out to roughly two to three pouches per six to eight pounds of body weight when fed alone. Opened pouches want refrigerating for seven to ten days.
Our mild opinion on multi-pet households: separate the bowls rather than policing them. A baby gate, a different room, or feeding the cat somewhere elevated solves this permanently and takes one afternoon. Trying to supervise two animals at every meal forever does not work and makes everybody tense, including the people.
If your cat has been raiding the dog's bowl for a while and you are wondering whether it has done any harm, that is a question for your veterinarian rather than for us, and it is a reasonable one to ask at the next visit.
Check the moisture percentage before you compare any two foods on protein. It is the single most useful habit in reading a pet food label.
