For a cat, wet food is a wonderful food treat. The good stuff has plenty of meat to get them excited as soon as they smell it. A human pops the lid off and the cat goes crazy until they can have it just below their mouth. Then they chow down. Depending upon whether they have trouble with their teeth or digestive trouble, wet food could be a necessity so the cat won’t go hungry. Usually, it’s just a treat compared to their regular food they eat.
I’ve noticed when I give wet food to the cats I live with, they tend to clean their teeth more than when they eat dry food. I find that a good thing when cats have complained whenever I’ve tried to brush their teeth.
