unless it’s a freeze-dried dry food, all commercial dry cat food is too high in carbs and too low in moisture for cats. Maybe there’s one out that that isn’t high carb, but it’s still low moisture, and I just about guarantee it’s more $$ than feeding a decent quality canned
Fancy Feast Classics is a fairly economical (for 1 cat at least) canned food that’s actually decent quality, and better than any dry food
We had a rash of crystal issues many years ago, which prompted me to switch to homemade. It’s a vet-designed recipe and has served us well for years
It’s time-consuming to make each batch, but 50lb of bone in skin on chicken thighs as the base, gives me enough food to feed 6-7 cats for a couple months. You do need a grinder which isn’t cheap, but its cost is quickly made up by how much is saved not buying commercial food. That 50lb of chicken at $1.38/lb, plus (the next most $$ part) 34 eggs, plus pennies to a few dollars for the rest of the ingredients like fish oil, vit e, b vitamins, taurine, lite salt, chicken liver, means that for < $100 I can feed 6-7 cats for at least 2 months, whereas the previous reasonable quality canned food (bought in 12-13oz cans for less $ per oz than 3-5oz cans) was around $400 for 3 cats for about 3 months
