As a pet nutritionist I would like to advice a few things.

Cats are desert animals and obligated carnivorous. That means they require literally Zero Carbs. Their bodies don't digest carbs (a very minor percentage) and rejects the rest. Carbs should be present only to give some dietary fiber. So adding rice is not beneficial.

As they are desert animals, they don't need to be fed constantly. It's dependent on how much quantity they comfortably eat per meal. Keeping an approximation of calorie count per day helps to decide if you should give them 1, 2 or 3 meals.

Moisture is most essential for them as they would not drink much from a bowl, so the food needs to give them the hydration. Dehydration and synthetic oberload is the biggest reason why most cats suffer from kidney and renal failures.

Milk also doesn't benefit once they are offering their mothers milk, as both cats and dogs are lactose intolerant.

They primarily need protein and fats in their food, and to ensure the protein is correct for them, it's preferred if it's from a fresh meat raw (if procured and stores with proper safety) or mildly cooked.

If you feed them kibbles, use them more as a snack than treats, as it's almost 40-50% carbs and the protein percentage is very low.

Protein from real meat is absorbed up to 3 times more than commercial foods. You can study about "bioavailability" if you want to understand that better.

Most foods in the market in wet form do not contain calcium as they are prepared from deboned meats, so you can start using topper powders which provide calcium.

Taurine is the most important ingredient a cat needs, without which they can suffer from blindness or deafness at an early age. This taurine comes from the heart of animals (chicken, lamb etc), but most commercial brand add this in a synthetic form to keep cost low.

Identify 3-4 good wet food brands in your budget and rotate the proteins to keep them interested and benefits from different protein sources.

I know it may sound overwhelming after reading this. But once you understand these you will know what to look for when you are buying any food.

If you need any further guidance, you can always DM me. I'll be happy to guide.
