But what is gluten anyway, and how does it affect your cat? Though gluten gets a bad rap in the human world, it isn’t actually anything that’s inherently dangerous or unhealthy. It’s not necessarily a great ingredient in your cat’s food, but it won’t hurt him. That being said, there are certain implications to consider if you’re thinking about switching your cat to a gluten free diet.

In this article, we’ll talk about gluten free cat food including what gluten is and why you should (or shouldn’t) care. You’ll also learn the basics about gluten free cat food and how to shop for it.

What is Gluten, Anyway?

Gluten is a type of protein found in cereal grains including wheat, barley, and rye. In human foods, it’s what helps bind ingredients together and it gives bread its spongy texture. Though the fact that it’s a protein might sound like a good thing for your cat, it’s important to remember that gluten comes from plant-based ingredients which are less valuable for your cat than animal ingredients are.

In cat food, you’re most likely to see gluten-containing ingredients in the form of wheat or wheat gluten. Some recipes contain pearled barley, but very few contain rye. If you see the ingredient “corn gluten” or “corn gluten meal” on the label, know that it’s a different kind of gluten – not the kind that triggers a reaction in people with celiac disease.

Is Gluten Free Cat Food Necessary?

As a pet owner, it’s your responsibility to provide for your cat’s needs. In order to do that, you may need to put your own personal preferences aside and do what’s right for your cat. Many pet owners who follow a plant-based diet themselves are starting to enforce the same diet on their pets which, many pet nutrition experts agree, is not a healthy choice.

Though certain healthy plant foods like whole-grain wheat and pearled barley, as well as processed alternatives like wheat gluten, do contain some protein, they aren’t ideal for cats.

Remember, your cat is an obligate carnivore which means his body is simply not adapted to subsisting on plant foods. True carnivores have a short digestive tract and don’t have the necessary bacteria in their gut to efficiently break down plant foods. This is all to say that, gluten free or not, a plant-based diet is not good for your cat.

But is gluten free cat food still necessary?

Generally speaking, there’s nothing particularly unhealthy about gluten. Remember, however, that it is a plant-based protein and therefore less biologically valuable for your cat than animal protein. Gluten-containing whole grains can provide certain nutrients and dietary fiber, but they shouldn’t make up a significant portion of your cat’s diet.

Special Considerations with Gluten Free Cat Food

When shopping for gluten free cat food, you should remember that gluten isn’t just found in wheat – it’s also found in barley and rye. Many pet food manufacturers will mention their product being gluten free on the label, but it isn’t as big a claim as being grain free.

Keep in mind that any cat food that is completely grain free will also likely be gluten free. It’s pretty uncommon for pet food manufacturers to use gluten-containing ingredients other than grains.

If you’re thinking about feeding your cat gluten free food, ask yourself why. In humans, a gluten free diet is a medical necessity for people with celiac disease and gluten sensitivities. Celiac disease is not a concern for cats, but food allergies can be. The most common cat food allergies, however, are animal proteins like chicken and beef. Grain allergies are not as common as pet food manufacturers would have you believe, so unless your cat has a wheat allergy, a grain free diet may not be necessary.

That being said, wheat is generally a less nutritious option for cats than other whole grains like brown rice or oatmeal. If you’re concerned about gluten but don’t need to go fully grain free, look for a cat food made with whole grains like these instead.

What Should You Look for in a Good Cat Food?

When it comes to shopping for cat food, gluten free shouldn’t be the first thing you look for. Remember that protein should be the foundation of your cat’s diet, and it should come primarily from animal sources. Carbohydrates, even gluten free ones, should be in very limited quantity and certainly secondary to protein and fat. There’s no harm in shopping for gluten free cat foods, but make sure to focus on what really matters above all.

Here are some things to look for in a good cat food:

  • Real animal protein as the first ingredient. A named source of meat, poultry, or fish should be the first ingredient (and ideally two of the first three) in your cat’s food. Plant proteins like pea protein and potato protein are less biologically valuable than things like chicken or beef meal.
  • Healthy animal-based fats. Fat acts as a source of energy for your cat and helps his body absorb fat-soluble vitamins. Like protein, it is most biologically valuable from animal sources, but it needs to be in balance with protein to keep the calorie content of the recipe moderate.
  • Digestible carbohydrates and low-starch veggies. The lower the carb content of your cat’s food, the better, but digestibility matters as well. Whole grains like brown rice and oatmeal are more nutritious than refined grains like wheat and corn. Look for low-starch veggies as well.
  • No artificial colors, flavors, or preservatives. These ingredients may improve the appearance of cat food but that’s not what your cat is concerned about. Artificial colors, flavors, and preservatives play no beneficial role in your cat’s diet.
  • Limited use of synthetic supplements. Most cat foods contain a list of added vitamins and minerals at the end, but you’ll also see free amino acids sometimes. The fewer additives in the product, generally speaking, the higher the quality. Added supplements usually means lower quality in the main ingredients or that there’s been significant nutrient loss during processing.

Now that you know what to look for in a high-quality cat food in general, you’re ready to start shopping on your own! Before you do, however, we want to tell you how we make our cat food recommendations so you know whether you can trust the picks we’ve reviewed in depth below.

The 10 Best Gluten Free Cat Foods

When shopping for gluten free cat food, checking for the “grain free” designation is the easiest way to go.

Frequently Asked Questions

  1. Do cats need a gluten free diet?  There is no all-encompassing answer to this question because different cats have unique dietary needs and preferences. Gluten is certainly not a necessary ingredient in your cat’s diet, but it isn’t all bad. It’s simply a type of protein found in wheat, barley, and rye. Whole grains in limited amounts can add certain nutrients as well as fiber to your cat’s diet, but plant-based ingredients are inherently less biologically valuable for cats than animal ingredients.
  2. Is grain free food good for cats?  Though pet food manufacturers have led consumers to believe otherwise, grain allergies are generally not the most common cat food allergies. In fact, it’s animal proteins like chicken and beef that are more likely to cause a reaction in sensitive cats. The only time you need to feed your cat a grain free cat food is if he has a confirmed allergy to grains. Many people assume that grain free means a cat food is also low in carbohydrates, but that isn’t necessarily true. A high-quality cat food rich in animal protein with low content of whole grains is typically better than the average grain free cat food because these tend to be high carb and have a higher concentration of plant proteins.
  3. What is gluten used for in cat food? Gluten-containing ingredients are often added to pet food to increase the protein content. You’ll see things like wheat gluten or corn gluten meal in lower quality products where the manufacturer is trying to increase the protein percentage on the label without significantly increasing their costs. This is why it’s important not just to check the guaranteed analysis, but to also review the list of ingredients on your cat’s food so you can make sure the nutrients listed come from quality sources.
  4. What about vegan and vegetarian cat food? As we mentioned earlier, vegan and vegetarian cat food is not ideal. It’s not even biologically appropriate. Vegan pet food manufacturers will tell you cats can get all the protein they need from plant sources, but what they’re not telling you is that it isn’t the ideal diet. Plant proteins contain essential amino acids, but only animal proteins are considered “complete” proteins – they contain all of the amino acids your cat needs. Many vegan and vegetarian cat foods rely on free amino acids being added back into the food to meet your cat’s minimum requirements. Remember, what’s most important is feeding your cat a diet biologically appropriate for his body – your own dietary preferences don’t factor into this decision.
  5. How do I know if my cat is allergic to gluten? Allergies in cats often present with different symptoms than they do in humans. Though digestive issues like chronic diarrhea and vomiting may be involved, recurrent ear infections and skin or coat problems are more telling. The thing to remember is that cats can develop an allergy to just about anything in their food, so before you assume it’s gluten, ask yourself if you’re sure. If you’re not, try switching to a cat food made with a different source of animal protein. A true gluten allergy is fairly rare in cats, so it’s worth ruling out other potential allergens first.

If you follow a gluten free diet based on medical necessity or you’ve simply hopped on board with the trend, don’t assume that your cat should too. Your nutritional needs vary significantly from your cat’s, and so does your body’s ability to digest plant foods. Gluten doesn’t provide more nutritional benefit than animal protein, but it isn’t necessarily harmful for your cat.

Before you go and spend a small fortune on a fancy gluten free cat food, ask yourself whether it’s really necessary. If gluten is the concern, all you really have to do is look for a recipe that doesn’t contain wheat, barley, or rye. To get started in your search, try one of the recipes recommended above.
