The reasons for adding a quality canned food: add moisture to the diet, quality canned foods have a good amount of protein since they don’t need carbohydrate binders like kibble, it’s easier to digest since it’s not hard and dry like kibble, they don’t have preservatives in them, and it’s easy to mix in powdered supplements. Canned foods are more species-appropriate than dry pellets.
Drawbacks: softer stool sometimes and the canned foods usually don’t include probiotics. They might have prebiotics like inulin/chicory root.
You don’t have to stick with the same brand of wet as you are using dry. Use various brands and feed a rotaional diet.
