Fish-based cat foods can be high in phosphorus, which is especially bad for kittens. Adult cats can have some fish-flavored canned food.

I definitely recommend at least some wet or fresh/raw food for cats. They tend to dehydrate easily because they don’t like standing bowl water… and chronic dehydration can also lead to urinary and bladder issues (especially bad for male cats). A pet water fountain can help encourage cats to drink more, though.
