What is Grain-Free Cat Food?

Grain-free cat food is a cat food made without the use of things like corn, wheat, soy, oats, barley, or rice. It is available in any form of cat food, from kibble to pate to raw food.

Is Grain-Free Food Better for Your Cat?

Not necessarily. Some cats do not need grain-free food – grains are actually one of the least likely causes of food sensitivities. Most cats’ allergies stem from intolerances to beef, dairy products, and fish.

However, grain sensitivities and allergies are possible. Plus, grains are not part of the cat’s natural diet, and for some cats, they can be hard to digest and process.

If you are not sure whether a grain-free cat diet is a better choice for your feline friend, it is advisable to talk to your trusted veterinarian.

CRAVE Grain-Free Adult Natural Dry Cat Food

It comes in three different recipes and protein sources – chicken, chicken & salmon, salmon & ocean fish. It provides all of the essential nutrients a carnivore needs. It contains no by-products or fillers and is suitable for cats with sensitive stomachs. The kibble is crunchy and comes in three bag sizes – 2 lb, 4 lb, and 10 lb.

Type: Dry cat food

Best for: Adult cats

Price: $2.87/lb

  • Protein-rich (40%) formula
  • Real chicken is the first ingredient
  • Cat-friendly kibble size and texture
  • No fillers, by-products, and soy
  • Budget-friendly price
  • Some cats may dislike peas

Ingredient Analysis: The first ingredient in the food is always an animal protein like real chicken or real salmon. These are great for protein and fatty acids. To additionally boost the protein content, it uses pea protein and potato protein. Dried plain beet pulp, split peas, and lentils offer dietary fiber and digestible carbs. The formula has mineral and vitamin supplements for complete nutrition.

Review: This grain-free cat food has over 7,000 reviews, and 90% of them are four and five-star ratings. Cat owners were happy with the effect this food had on their cats’ issues, claimed their old cats could eat it without digestive upsets, and the overall quality was great.

Purina Beyond Grain-Free Natural Dry Cat Food

Summary: This dry cat food is made with wild-caught whitefish, cage-free eggs, and accents of sweet potatoes. It is both grain and gluten-free and suitable for cats with sensitive tummies. Plus, the formula contains natural probiotics for additional digestive health. Each ingredient in the food can be traced back to its source. The food is available in one flavor and three bag sizes – 3 lb, 5 lb, and 11 lb.

Type: Dry cat food

Best for: Adult cats

Price: $3.32/lb

  • With meat, eggs, and sweet potatoes
  • Gluten-free and grain-free recipe
  • Added probiotics for digestive support
  • No artificial flavors or preservatives
  • 100% traceable ingredients
  • Contains canola meal and sunflower oil

Ingredient Analysis: The first two ingredients are hake and chicken meal, a good indication this is protein-rich cat food. Pea protein and dried egg products supplement the protein content and add fiber, carbs, and fatty acids to the blend. Sweet potatoes are used as a carbohydrate source but are used in relatively small amounts, while a mix of vitamin supplements rounds up the cat’s diet. The only ingredients we dislike are canola oil and sunflower oil.

Review: 95% of the over 5,400 reviews on Amazon rate this grain-free cat food with 4 or 5 stars. Numerous buyers state they made the switch from Hill’s Science Diet and Purina Pro Plan after they became intolerant to some ingredients, and this food has cleared up those sensitivities. The few negative remarks mostly repeated the same points that cats won’t eat it or that there were bugs in the food upon delivery.

Taste of the Wild Grain-Free Recipe Dry Cat Food

Summary: This is a limited ingredient, grain-free pet food that uses Angus beef as the primary source of lean animal protein. The added probiotic blend makes the formula easy to digest and fit for cats with sensitive stomachs. It also promotes healthy skin and coat. The food is complete and balanced for cats of all life stages – from kittens to adults to senior cats.

Type: Dry cat food

Best for: Cats of all life stages

Price: $4.53/lb

  • With Angus beef and lentils
  • Rich in omega fatty acids
  • Contains probiotics (80 million CFUs)
  • Can be used as a kitten food
  • Includes probiotics
  • Available in large bags (15-pounds)
  • Sunflower oil is one of the key ingredients

Ingredient Analysis: There are three key ingredients in this food – beef, lentils, and sunflower oil. Beef is a great source of protein and animal fats for carnivores. Lentils provide prebiotics and easily digestible carbohydrates. The formula is enriched with dried fermentation products from beneficial bacteria. The only ingredient we dislike is sunflower oil – it adds fatty acids but may not be the best fit for cats.

Review: There are fewer reviews of this grain-free cat food than some of the others on this list, but the majority of them are positive. The 4 and 5-star reviews are happy that their cats enjoy this food and like the fact that it is grain-free.

  • Minimally processed ingredients
  • Available in variety packs

Blue Buffalo Freedom Grain Free Natural Indoor Dry Cat Food

Summary: This dry food is made with real chicken as the first ingredient. It is formulated to give complete and balanced nutrition for adult cats and comes in two different flavors – chicken and fish. The formula includes Blue Buffalo’s hallmark signature – the health-boosting LifeSource Bits that are concentrated morsels of vitamins, minerals, and antioxidants. It supports easy digestion, healthy weight, and strong immunity. The kibble comes in two bag sizes – 5 lb and 11 lb.

Type: Dry cat food

Best for: Adult cats

Price: $4.50/lb

  • Real chicken or fish for the first ingredient
  • Cold-formed to preserve the potency
  • Contains the brand’s LifeSource Bits
  • No by-products and artificial preservatives
  • Helps with digestion and weight control
  • Limited flavor selection

Ingredient Analysis: Real chicken and fish are used as the first ingredients to provide excellent sources of protein and omega-fatty acids. Sweet potatoes are added for complex carbohydrates, and blueberries and cranberries are included for their antioxidants that support a cat’s immune system. We particularly like that the formula does not include fillers, by-products, and artificial ingredients like colors, flavors, and preservatives.

Review: With over 2,000 reviews on Amazon and 94% of them coming from 4 and 5-star ratings, many people are happy with this grain-free cat food. They are pleased it helped their cats with food allergies to feel better and that the higher fiber in this food helps to control hairballs. A small number of pet parents also expressed satisfaction with this food having fewer calories than the food they were previously feeding their cats. One and two-star reviews only made up 3% of the total reviews, but they all say more or less the same thing. They claim their cat had become sick after eating, and some said their vets had told them to steer clear of a grain-free diet.

Purina Cat Chow Natural Grain-Free Dry Cat Food

Summary: This grain-free diet is made with real chicken as the number one ingredient. The food is free from artificial ingredients and fillers, but it does contain quite a few plant-based ingredients. It is very high in omega-3 and omega-6 fatty acids, which support skin & coat health. This cat kibble comes in three bag sizes – 3 lb, 6 lb, and 13 lb and is fit for adult cats. Based on the manufacturer, every ingredient in the formula has a purpose.

Type: Dry cat food

Best for: Adult cats

Price: $3.00/lb

  • Real chicken for a high protein content
  • Made with 0% fillers
  • Rich in omegas for skin & coat health
  • No artificial colors, flavors, or preservatives
  • Very affordable price tag
  • Contains cassava root flour
  • Relatively low in crude fiber

Ingredient Analysis: Chicken is the first ingredient, which is great, but the second ingredient is a chicken by-product. This is an unnamed by-product, so it is difficult to know the reason for the ingredient or the nutrient content. Almost every ingredient after chicken by-product is plant-based. Canola meal, cassava root flour, and pea protein are relatively high on the list, and these may not be ideal for carnivores.

Review: With thousands of reviews, most of them being five stars, this grain-free cat food appears to be a good choice in the eyes of consumers. With 95% of reviews being four stars or higher, the main point they touch on is how much their cats enjoy the flavor of this food. Some say their cats with sensitive stomachs have seen improvement in their symptoms, and they are all happy this food does not come with a high-end price.

What Should I Look for in Grain-Free Cat Food?

When shopping for the best grain-free cat food, there are several things to consider:

  • Meat as First Ingredient. Cats are carnivores, so they require meat to live. High-quality grain-free cat food should have meat as the first ingredient. Many cat foods that market themselves as grain-free may, in fact, be grain-free, but the ingredients they use might also be less than ideal for your cat, so make sure meat is the first ingredient.
  • Organ Meats and Animal Products. Organ meat is a superfood for cats. It provides them with the vitamins and minerals they require that aren’t in muscle meat and may be in grains. If organ meat is in a food that is also labeled “grain-free,” it likely has the micronutrients your cat would have otherwise received from those grains.
  • Formulated by Experts. Animal nutritionists know what a cat will need to be healthy. Replacing grains with other vegetables as a carb source can be tricky and is best done by someone with in-depth knowledge of what a cat really needs, if not grains.

Are Grain-Free Cat Foods Gluten-Free?

Yes, grain-free cat food is always gluten-free. Gluten is found in some grains like wheat, barley, and rye. So, if the cat food is free from grains, it does not have a gluten source.

However, pet owners should understand that not all gluten-free foods are grain-free. For example, rice, millet, and amaranth are grains but they do not contain gluten.
