Not the person you responded to, but my vet strongly urged me to transition my cats to primarily wet food, saying that the cheapest wet food is still better than the best dry food. I could go on and on and on, but to be brief, they provide different ratios of carbs:protein (cats are obligate carnivores and require almost zero carbs) and cats that eat primarily wet food are much more likely to be adequately hydrated.

The cheap pet food at supermarkets. Anything Purina. I’d argue any supermarket pet food, but I’m not a animal nutritionist.

I currently buy pet food from small pet food stores that have a wider variety. Currently I feed them this 4-ingredient dry cat food that costs like 4x times the supermarket price, and daily wet food recommended by the vet.
