Purina Cat Chow is literally one of the worst foods, ever. The ingredients are below.
You're forgetting Science diet. Even the stray I feed objected to that, although he ate it. He was hungry. I finally gave it to the neighbour for their chickens.
Dry food is very bad for cats. .
Nonsense! I've posted before, and I'm not going to be doing it again, an article where 32 cats, most of them with a chronic disease the name of which I can't recall were fed a standard commercial diet for 70 weeks during a scientific experiment. The experiment had nothing to do with food.
That the cats were happy and loved was far more important. They were caged most of the time with one hour's excercise tiemper day. The health of all the cats either improved or did not deteriorate.
As with all living things,including plants and people, the results with the individual life form varies for different foods.
I dislike this condemning of dry foods because it lays a guilt trip on the guardian/caregiver who may not be able to afford better, but who is able otherwise to give a cat a home.
There are people who feed 'good' food and overfeed their cat to the point of obesity. THIS IS BAD.
Also, many of the 'GOOD' wet foods contain similar animal stuff that is not fit for human consumption, but the naming is aimed at the human diet desires.
I see, for instance, green peas in foods. Pea protein is of course 'vegetable' (condemned by some for cats), and peas contain carbs -- yes!
Most cat food is manufactured in China these days and is apparently nuked (irradiated) to kill any pathogens.
For the record, Missy get a varied diet. Her dry food is a store brand, Nutrition First, double the Purina price, that doesn't contain grains. Purina Friskies wet; mostly Salmon Dinner because this is what she prefers. She also gets treats once a day, plus doctored tuna for her constipation (she had it when I brought her home from the shelter). She also gets snacks of chicken if I'm having it, and snacks of ham flakes, or turkey flakes. (So I spoil her. She's old like me, so why not?
