Whole grains are good for you, right? Things like whole-grain oats, whole wheat, and whole brown rice. Other grains like corn aren’t bad when they’re whole-grain, and some soy products offer health benefits.
- Rich in real animal protein
- Blend of omega-3
What about your cat? Whole grains are complex carbohydrates which provide energy, dietary fiber, and essential nutrients. They are much more nutritious than processed or refined carbohydrates and they are fairly digestible in moderate amounts. With corn, wheat, and soy, however, it’s a different story. These grains offer limited nutritional value to cats and their quality in cat foods tends to be fairly poor. We personally avoid any cat food that contains corn, wheat, and soy ingredients because they are commonly used as fillers and don’t do your cat much good.
In this article, we’ll explore the subject of grains like corn, wheat, and soy in cat food to help you understand their role in cat food and how to identify them on a pet food label. From there, we’ll show you what you should be looking for in your cat’s food and provide you with our top picks for the best cat food without corn, wheat, or soy ingredients.

Corn, Wheat, and Soy in Cat Food
In cat food, corn has been a controversial ingredient for years. Not only is it difficult to digest, but it offers limited nutritional value in addition to being a common trigger for cat food allergies. Wheat is similar, especially in its most processed forms. Not only are both difficult for cats to digest, but they are often used as supplemental proteins in cat foods.
What’s the problem there? Plant protein simply isn’t as nutritious or as biologically valuable for cats as animal protein. But it’s more complicated than that.
Cats are obligate carnivores which means they have a biological need for meat in their diet. They do not possess the digestive enzymes necessary to break down carbohydrate, so they aren’t able to utilize simple sugars as a primary source of energy. They have short digestive tracts as well and no functional cecum, the part of an herbivore’s body that contains beneficial bacteria which help digest plant fiber. All of these things combine to make it very difficult for cats to digest plants.
But what about soy in cat food?
Pet food companies often use wheat gluten and corn gluten as supplemental sources of protein – soy protein is similar. All three are cheap fillers used as substitutes for the real meat your cat’s body needs for optimal health. You can see the problem.
In addition to the issues already mentioned for corn cat food and wheat in cat food, soy products have a specific impact on your cat’s body. Soy contains a compound called phytates which inhibits healthy mineral absorption and blocks the enzymes needed to digest protein. This causes inflammation of the GI tract which can lead to serious health problems. It also interrupts the function of the thyroid, the gland that controls the hormones that regulate metabolism and other essential functions.
By now you can understand the problem with corn, wheat, and soy in cat food, but you may be wondering whether other grains are bad for cats. Read on to find out.
Are All Grains Bad for Cats?
Think back to what we said about whole grains. Things like whole brown rice, whole-grain oats, and whole pearled barley are some of the most nutritious grains out there, for both pets and people.
However, when pet food manufacturers use by-products of the human food grain processing industry like wheat middlings, rice bran, corn gluten, and soybean hulls they don’t offer the same degree of nutrition. In fact, they may take the place of more nutritious ingredients like animal protein and increase the risk for triggering a food allergy or sensitivity. This is why you should look for a cat food without corn or wheat and avoid soy ingredients as well.
So, it’s probably best to feed your cat a grain-free diet, right? Not necessarily.
Grain-free cat food is simply cat food without grains, but that definition doesn’t tell the whole story. Instead of being able to use common carbohydrates like rice, pet food manufacturers use things like peas, legumes, and potatoes. The problem with these ingredients is that they tend to be high in protein which can raise the total protein content of the recipe, misleading the customer to think it’s a better option for their cat than it really is.
Legumes may be edible for people, but there is some concern about their impact on pet health. The FDA is currently investigating claims related to grain-free pet foods and an increased risk of dilated cardiomyopathy (DCM), particularly in dogs.
What about cats?
Legumes contain high levels of phytic acid which have a tendency to bind calcium, magnesium, and iron in animals. The lectin proteins in legumes can also be problematic because they are a plant’s natural defense system. Birds are able to digest these proteins, but carnivores cannot. They also attach to the villi lining the digestive tract, blocking the absorption of nutrients.
What Should You Look for in a Healthy Cat Food?
We highly recommend looking for a cat food without corn products and you should also avoid soy and wheat products as well. Don’t just jump for the nearest grain-free cat food however, because certain grain-free plant ingredients may be just as harmful. Your best bet is to start with a high-quality recipe made with a real source of animal protein as the main ingredient with limited content of highly digestible carbohydrates.
Here are some general things to look for in cat food:
- High in quality animal protein. Protein is the foundation of a healthy diet for cats, so look for a source of high-quality animal protein like meat, poultry, or fish as the first ingredient.
- Moderate content of animal-based fats. In the same way that animal proteins are more biologically valuable for your cat, so are animal fats. Look for things like chicken fat or salmon oil as primary sources with plant oils as supplemental sources of omega-6 fatty acids.
- Limited content of digestible carbohydrates. The lower the carbohydrate content of your cat’s diet the better and it needs to come from digestible sources like whole grains and vegetables.
- No generic by-products or artificial additives. Things like chicken by-product meal and beef by-products are not necessarily bad but avoid generic things like animal digest or meat by-product meal. Avoid artificial colors, flavors, and dyes as well.
- Complete and balanced nutrition. Make sure any food you choose for your cat is labeled “complete and balanced” according to AAFCO food nutrient profiles.
Now that you know what to look for in a good quality cat food, you’re ready to start shopping! Before you do, however, we want to clue you in to how we make our cat food recommendations so you know you can trust them for your cat.

Most Popular Cat Food without Corn, Wheat, or Soy: Because there are hundreds of cat food brands out there, it can be difficult to choose one. We recommend Taste of the Wild as a popular option you can trust because they use premium animal proteins and other whole-food ingredients in all of their recipes. This Rocky Mountain Grain-Free Canned Cat Food features fresh salmon as the main ingredient with fish broth and chicken broth for natural flavor and moisture.

Chicken fat provides a nutritious source of essential fatty acids while flaxseed and menhaden fish meal supply omega-3 fatty acids. You’ll find fresh fruits and vegetables like apples, spinach, blueberries, and carrots to provide natural sources for key nutrients with cranberries for urinary health. This recipe is free from grains including corn, wheat, and soy with tapioca starch as the primary carbohydrate. It does contain some pea protein, but four animal proteins come before it, so it may not significantly contribute to the 40% protein content.

Frequently Asked Questions
- What cat food ingredients should I avoid? The thing you need to remember is that cats are obligate carnivores, so their bodies simply are not evolved to digest plant foods. Your cat’s diet should be protein-based with moderate amounts of fat and as little carbohydrate as possible. Any carbohydrates in your cat’s food need to come from high-quality, digestible sources like whole grains and vegetables. Generally speaking, you should avoid corn, wheat, and soy ingredients as well as by-products of unknown origin (things like animal digest or poultry by-product meal). You should also avoid artificial additives like colors, flavors, and dyes.
- What are byproducts in cat food? The Association of American Feed Control Officials defines byproducts as, “secondary products produced in addition to the principal product.” Essentially, by-products are the leftovers after the desired product has been extracted or processed. In pet foods, this may include things like bran or hulls from whole grains and feet, skin, and organs from poultry. Not all by-products are inherently bad, but you should be cautious about trusting a product that incorporates more by-products than whole ingredients. You should also avoid generic by-products from meat or poultry instead of beef or chicken.
- Is grain-free cat food good for my cat? There is no simple yes or no answer to this question. If your cat is allergic or sensitive to grains, grain-free cat food may be the best option. Otherwise, however, grains (specifically whole grains) can be a nutritious addition to your cat’s diet in low to moderate amounts.
- Where can I find a cat food without corn, wheat, or soy? The good news is that most high-quality pet food companies don’t use corn, wheat, or soy products in their recipes. Just because a brand has a popular reputation and a wide product selection, however, doesn’t mean you can trust it. Brands like Purina and Science Diet that have a huge following and a long history in the pet industry make heavy use of these ingredients. You need to do your own research and check the ingredients list before you buy.
- What ingredients are better than corn, wheat, and soy? If your cat is allergic to grains, you should be looking for nutritious alternative sources. Try to avoid cat foods that make heavy use of peas, legumes, and potatoes. Fresh vegetables are a better alternative. Keep in mind as well that cats have no biological need for carbohydrates in their diet, so a no-carbohydrate recipe may be even better as long as it is nutritionally balanced. Fresh vegetables are a natural source of key nutrients, however, so it is better to choose a recipe that contains some vegetables than one that relies entirely on synthetic supplements.
The cat food industry is huge and there are hundreds of products to choose from. Many of these products have excellent ratings on pet food retail sites like Chewy, but you can’t necessarily trust those ratings. Just because a pet likes a food doesn’t necessarily mean it’s good for them and some of the most popular brands on the market make heavy use of low-quality ingredients like corn, wheat, and soy products. If you’re looking for a cat food without corn, wheat, or soy you still have plenty of options, but you’ll need to spend a few extra minutes reading pet food labels to find them.
If you’re really not sure where to start, you can always try one of our recommendations above. We’ve also explained how we make those recommendations, so you know you can trust them!
