Wet food does not harm the teeth. Dry food can. Fancy Feast is a good brand that is low cost. Check out chewy.com to get an idea of the price range you want to go. My cat Peaches has a sensitive tummy and does well on the Dr Else's canned. Also feed it to Coco. It is good to feed your cats a wide variety of meats. My cat Maggie eats wellness Core mostly. It has more meat in it which is what she needs. Pricy so I am going to switch to Dave's cats meow. Peaches and Coco get 3/4 5 1/2can a day split in 3 meals Maggie one whole can. Lately I have been giving them pate morning and night and split a 3 oz can mid day. Fish is high in mercury so no more than once a week. They alternately eat chicken,turkey,duck beef,lamb,quail. Beef can cause loose stools so beware
