It’s no secret to cat owners that when it comes to feeding them, the variety of foods available is almost endless. So many brands, so many flavors, all with their glitzy ads trying to convince you that their food and theirs alone is the best. It can make it pretty hard to choose, right?
You may be surprised to know there is something many brands and flavors of cat food have in common, and that’s grains. All traditional cat foods have one kind or another, either wheat, corn, rice, oats or barley.
There are many pet owners and self-proclaimed experts that swear a grain free diet is superior and that grains are bad for cats but according to clinical veterinary nutritionists at Tufts University, that’s not at all true Despite what you may have heard, grain-free is more a marketing trend than a nutritional breakthrough.
Cats can get nutrition from grains just fine, say, veterinarians. So why the big push? Well, just like low carbs and gluten-free have turned into dietary buzzwords for humans, the term grain free is used to make pet owners think that type of food is better for your pet because grains are evil.
The truth is they’re not. Grains aren’t harmful to your cat, and most cats have no trouble digesting them. There are some exceptions, which we’ll get to later. While overall grain-free food does tend to offer higher quality ingredients, such as chicken and beef instead of grains and fillers, it doesn’t necessarily mean it’s lower in fat and calories or healthier.
However, unlike traditional foods, where grain or fillers may be the first ingredients, with grain free foods, the primary ingredients are almost always beef, poultry, game, or fish, which is better for your cat.

First, let’s take a closer look at the basics of cat nutrition:

Cat Diet Basics
Unlike us, cats are obligate carnivores. That means their bodies cannot get nutrition from anything but meat. If you tried to turn your cat into a vegetarian or vegan, they would become very sick, because despite veggies, fruits, and legumes being very healthy, their bodies cannot access the nutrients in them. They need the protein meats provide. They can and often do enjoy fruits and veggies though. Some cats find them quite delicious!
However, cats NEED meat beef and chicken are the most common ones used in cat food, but many brands also use fish, duck, turkey, venison, rabbit and even quail. So why do cat foods have grains at all? Good question!
The simple answer is that cat food companies are required to ensure their food meets mandated nutritional requirements, just like our foods must. One of those requirements is carbs, and they use grain, (usually wheat, corn or rice) to meet those requirements. Grain is cost effective and makes a good filler, both of which let them make the food cheaper and sell it for cheaper.
Most cats don’t have a problem with grains, although like with us, too many carbs can lead to obesity. Some cats do develop a gluten intolerance although it’s not yet known why. For them, grain free is a must.
That said, grain free food is not necessarily lower in carbs or calories than regular cat food because most manufacturers replace the grains with other types of carbs, including things like tapioca, various veggies, and even fruits such as cranberries, none of which are of much use to a cat. (Despite what you may have heard, cranberries have close to zero benefits for their urinary tract systems. We’ll talk more about that later.).
One quick note: Although you’ll often see fish as an ingredient in cat food, and that’s fine, it is not advisable to give your cat human tuna except as a very occasional treat. Regular consumption of tuna can cause liver problems in cats, and for reasons not yet understood, cats can become somewhat addicted to it!
So now that you’ve got the basics of a cat’s nutritional needs down let’s take a closer look at grain-free foods and what you can expect from them.
Grain free foods tend to be a bit pricier than regular cat food because manufacturers don’t have the savings advantage of using grains. They may also use exotic meats like rabbit, venison or bison, which also drives up the price, but can be worth it, as foods with meat as the first ingredient rather than by-products are better for your cat. It’s important to remember though that cost is not necessarily an indicator of quality when looking at grain-free foods. In a study in the Journal of Feline Medicine and Surgery, for example, the researchers found that one high-end food touted as grain-free had barley in it-a grain!
Read labels carefully if you’re looking for a grain free food and remember that although things like vegetables and fruits might look good on the label, they aren’t anything your cat needs and often just drive up the price. That’s not to say they’re bad for your cat! They just shouldn’t be the focus of the food.
Instead, look for quality ingredients like chicken, beef, eggs, turkey, and fish, which are all good sources of the protein your cat needs. Ideally, the first ingredient should be chicken, beef, or fish. If it is one of those things but ends in –meal, that’s okay. It’s just dried and ground meat. Least desirable is a first ingredient that ends in “by-product.” While it’s still meat, it’s the cheapest version and let’s just say you don’t want to know what’s in it!
Grain free foods are advertised as being easier to digest, healthier and lower in calories than regular food, but this isn’t always the case. It depends on what the manufacturer uses in place of the grains to fulfill the carbohydrate requirement.
Some replacements, like tapioca, are just as high in calories, while others, like apples and peas, are less so. If the grain free food you choose has a higher fat or carbohydrate count than the food you were previously giving your cat, adjust her portion sizes appropriately.
If your cat has a sensitive stomach, grain free foods may be an excellent option because they tend to be free of artificial colors, preservatives, by-products, and flavors, which are all things that can trigger food sensitivities. While corn, a popular grain found in traditional cat foods is not known as an allergen in cats, rice and wheat can be. So can fish and eggs, so if your cat is sensitive, try to avoid foods with those ingredients.
Another benefit many cat owners will appreciate is that since they don’t contain fillers or artificial ingredients, cats who eat grain free foods tend to have less smelly litter box deposits. Hurray! It is true-the better the food that goes into your cat; the more pleasant litter box duty will be.
That’s because a lot of the fillers cheaper foods use are not easily digested by cats and are eliminated in the litterbox, while higher quality foods are more digestible and leave less behind. The more fillers, the more output, and odor!
Cats with Food Allergies/Sensitivities
If your cat has food allergies, your vet may recommend grain free food for the reasons above. Since it has fewer fillers and more animal-based protein, it may be less likely to trigger them.
Are you uncertain if your cat has food allergies? Here are the symptoms to look out for:
- Excessive grooming
- Hair loss
- Bald patches
- Hot spots
- Digestive issues
- Inflamed skin
If your cat is showing any of these symptoms and you suspect a food allergy, contact your vet before changing her diet. Your vet will probably have you do an elimination diet first to try and pinpoint which food is causing the issue and will want to run tests to rule out any other causes. Since the symptoms can also be caused by several serious disorders, don’t skip this step.
Grain free foods tend to have ingredients that even humans would find appetizing: apples, potatoes, avocado, peas, carrots, chicken, beef, salmon, arugula and many more fruits and vegetables. You are also likely to find more exotic meats like rabbit, duck, bison and venison, all quite tasty to cats! If your cat is a finicky eater, the increased variety of flavors in grain-free food may be just what they need!
If you are concerned about things like artificial preservatives, MSG, and GMOs, you’ll be happy to know that grain-free foods tend to contain none of these things. They are also more likely to be made in the United States, rather than imported from overseas. Read the labels carefully to see exactly what you’re getting.
Dry or Wet?
Like regular cat foods, grain free foods come in both wet and dry varieties. Which is best is largely up to your cat’s preferences, but providing wet food is an easy way to ensure your cat is properly hydrated.
Many grain free foods have rich broths or gravies to help even more. If you have a cat that doesn’t seem fond of water, wet food is a definite must. If your cat has a primarily dry food diet, add some wet food to her kibble every so often for a treat and to offer additional hydration.
What About All Those Vegetables?
You probably noticed that most grain free food is packed with fruits and vegetables. While it may make you feel good to be giving such a healthy food, remember that cats are obligate carnivores, and in the wild, the only fruits and veggies they’d eat would be what was in the stomach of their prey.
That said, many cats enjoy fresh produce, and it won’t harm them at all. In fact, fruits and veggies can make a great alternative to traditional treats. Just be sure to stay away from onions, raisins, grapes, fresh garlic, mushrooms and persimmons which are toxic to cats.
Before You Make the Switch
If you’ve decided to try grain free food with your cat, be sure to do so gradually. Sudden changes in diet can upset cat tummies and lead to vomiting and diarrhea. Start by adding a little of the new food to your cat’s current food and over the next few weeks add more and more of the new food until that’s all they are eating.
Keep an eye on your cat during the transition for any signs that the new food may not be agreeing with them, and once you’ve made a successful switch, stick with it. Constantly switching brands can play havoc with your cat’s digestive system, so find one they love and stay loyal!
What to Watch Out For
While grain free foods are just fine for cats and can even be better quality than regular foods, there are some things to watch out for. For example, some grain free foods make a big deal out of the fact they contain cranberries, saying it is good for urinary health. While cranberries are commonly recommended for women who have urinary tract infections, the same benefits have not been shown in cats. Food containing cranberries won’t hurt them at all though. If your cat is showing signs of a urinary tract issue, see your vet, don’t try and treat it yourself.
Urinary tract infections are not particularly common in cats, but when they happen, vet treatment is a must. Cats, especially males, tend to form crystals in their urine, and due to the narrow urethras male cats have, it’s not uncommon for them to suffer a complete blockage. This blockage makes it physically impossible for them to pee and is a life-threatening emergency.
Another thing to watch out for is fat content. Due to their tendency to have more animal-based proteins, grain free food can be higher in fat than regular food. The same is true of carbohydrate content.
While cats do need some carbs, too many can lead to obesity and even diabetes. To avoid unwanted weight gain, make sure you are feeding your cat appropriate portion sizes and ensure that she’s getting plenty of exercise! If you’re feeding dry food, plenty of water is important too.
