My advice is read the contents label and then ask yourself: if my cat were wild and living off the land, would he/she be eating cornmeal gluten, wheat gluten or sugar? No. And they wouldn’t be consuming all the sugar and salt added to semi-soft food, either. That stuff is horrible for cats or dogs.
Thank you for the reply. I think I’m going to try Blue Buffalo canned in the morning and leave out the Royal Canin for free feed and see how they do. Neither has any health problems and are still young (6 1/2 and 16 mo.). They are both long-haired so they need the hairball control (especially the Ragdoll). I don’t like the idea of forcing petroleum products down them, if they can get what they need from the food.
