If a cat is allergic to one (or possibly more) of these ingredients in a dry food, how likely is it that he would be allergic to it in a canned/wet food?
Corn is a very popular allergen among cats - along with soy, wheat (gluten), and fish.
Other common allergens include any grain (any - including rice, barley, oat), beef, and venison.
My cat doesn't have any of the above allergies (none that I know of), but I always stay away from grain-containing and "fishy" flavored foods anyway. Fish isn't good for cats in high amounts, even if your cat isn't allergic to fish - and cats aren't really designed to eat grain.
Does your cat appear to have an allergy? I wouldn't just assume it was corn - try a food that has NO corn in it, and see if it allergies go away. If they persist, try one with no grain, if they persist, try a grain-free chicken variety.
Most cats can handle chicken. If yours is allergic, try duck, quail, or rabbit.
If he is allergic to it in dry food, he will likely be allergic to it in wet food, too. I wouldn't risk it.
