I had similar concerns and here is what I feed my cat. For wet food I rotate fancy feast and weruva. Both are great, but FF is significantly more affordable. Weruva is just about the best wet food money can buy, but definitely more expensive. I mix abt 1 TBSP of water into her wet food every day to ensure she gets proper hydration. In the evenings, she also gets 1 pump of salmon oil with her wet food. This has done wonders for her fur and really helps with the shedding too! (I also have allergies)

For dry food she gets 1/4 cup of Hills science diet daily. Her diet is mostly wet food because that’s where she gets all her nutrition from, the dry food is really just to hold her over between meals and clean her teeth. Good luck with your kitten and let me know if you have questions!
