The fiber in corn can help clean your cat's teeth to some extent, and by chewing on the kernels, you can remove some of the food debris and plaque from the surface of the teeth, thus helping to prevent oral disease. This is an added benefit for cats, especially if they don't receive specialized dental care on a regular basis. While corn may have a cleansing effect on your cat's teeth, it should be fed with caution and make sure it is cooked to make it easier to chew and digest. Additionally, corn should not be a major part of your cat's diet, as cats are carnivores and their main source of nutrition should be animal protein. When feeding corn, it should be controlled in moderation so that it does not affect your cat's overall nutritional balance or cause digestive problems.
When considering adding corn or any new food to your cat's diet, it is best to consult your veterinarian first to ensure that the food chosen is suitable for your pet and will not cause adverse reactions.
