How to Choose the Best Grain-Free Cat Foods

The best grain-free cat food will feature plenty of animal protein with healthy fats for energy and coat support. Because these cats are prone to kidney issues, proper hydration is essential, which makes fresh food and canned food a good option.

Here are some other things to look for in a grain-Free cat food:

  • Wholesome, all-natural ingredients. Real, whole-food ingredients are the most digestible and nutritious for your cat.
  • Plenty of animal protein. Protein supports your cat’s lean muscle mass and keeps it healthy. Aim for at least 26% but ideally upwards of 30% protein, primarily from animal sources, with limited carbohydrate content.
  • Rich in essential fatty acids. Fat provides a concentrated source of energy for your cat and should come from animal sources like chicken fat and salmon oil as much as possible. Just keep in mind that the higher the fat content, the higher the calorie content.
  • Highly digestible. High-quality ingredients are the most digestible for your cat, so look for a recipe that is made with wholesome, natural ingredients with no fillers, by-products, or artificial additives. It also doesn’t hurt if the recipe includes prebiotics and probiotics.
  • Rich in moisture. Choosing canned food for your Himalayan can boost its moisture intake. Another option is to moisten your cat’s kibble with water or broth, or you can add a moist or semi-moist food topper.

Understanding the Dietary Requirements of Cats

Your cat is an obligate carnivore which means that its body was evolved to digest and absorb nutrition from animal products more efficiently than plant products.

What does this mean for you? It simply means that meat should be the foundation of your cat’s diet – this includes animal-based proteins and animal-based fats for energy.

High-quality animal protein should be the first ingredient in your cat’s food. Cats require a minimum of 26% protein and 9% fat in their diets, but more is usually better.

Protein helps support strong muscles and lean mass while fats provide a concentrated source of energy as well as support for healthy skin and coat. Look for a blend of omega fatty acids and fats from high-quality, animal-based sources.

On top of protein and fat, your cat can benefit from fiber and essential nutrients. The carbohydrate content of your cat’s diet should be kept low to ensure digestibility, but things like whole grains and fresh fruits and vegetables can provide natural sources for key nutrients as well as dietary fiber.

Finally, look for vitamin and mineral supplements in your cat’s food to ensure complete and balanced nutrition.

Now that you have a better understanding of your cat’s nutritional requirements, you’re ready to start shopping around! Keep reading to learn what you should look for when shopping for organic cat food.

What Are Common Grains Used in the Pet Industry?

For those that may be a little more unfamiliar with what grains actually are, here’s some clarity.

Grains can be explained to be seeds from specific grasses that humans have begun to consume ever since they got civilized.

Not to mention that these grains usually contain a large number of carbohydrates, which is a good source of energy.

However, depending on how much is consumed, it can be good or bad for a specific animal.

The reason for this is that products with too many carbohydrates contain little to no protein, fiber, vitamins, and minerals.

To give you a better idea about grains, below-listed are some common examples that we may have seen or heard of. You may also discover them in your cat food:

  • Millet
  • Oats
  • Quinoa
  • Rice
  • Rye
  • Couscous
  • Corn
  • Bulgur
  • Buckwheat
  • Barley

The Pros & Cons of Grain-Free Food

There has been a lot of argument over the years on whether or not grain-free food or food that contains grains are worth eating.

On one side some people state that it is not natural to be eating grain-packed products, while others note that grain-free is no better for the pet.

The Benefits

Some of the noted positives of feeding your pet with grain-free food include:

  • Increase in activity levels – Since some grain-free foods include high-protein, some cat owners found their pets to turn more active.
  • Improvement in pet’s health – Some owners have stated that they’ve noticed their pet getting stronger and healthier with the absence of unnecessary grains.
  • Easier to digest – Corn and other grains are said to be a wee bit difficult for cats or dogs to digest, so any product that is grain-free will be easier to digest.
  • Processed grains are not healthy – This argument is why many tend to stick to grain-free food, rather than running the risk of feeding them with something that is not even considered healthy.

But Grain-Free Cat Food is Not Perfect

First of all, there is no perfect cat food. As shown below is a list of some of the noted negatives of feeding your pet grain-free food.

  • Can cause weight gain – It may be a lot easier for your cat to gain weight through eating grain-free food since it is packed with other high-protein ingredients. Unless you feed this to active pets, this could be even more of an issue.
  • Contains too many carbohydrates – A lot of the non-meat products listed on the package tend to contain more carbohydrates, which is non-nutritious.
  • Expensive – Grain-free food tends to be more expensive than the typical grain-packed pet foods.

What About Food Allergies and Sensitivities?

In addition to thinking about the quality of your cat’s food and mixing dry and wet food you should also think about the potential for food allergies and sensitivities. 

Cats have the potential to develop allergies at any point in their lives and common allergens include beef, chicken, dairy, wheat, corn, soy, and artificial additives.

If your cat has itchy skin, recurrent ear infections, or a dry and brittle coat, it could be suffering from a food allergy. Switch to a hypoallergenic cat food made without the ingredients your cat is allergic to or try a limited ingredient diet to reduce the risk for triggering food allergies.

What Studies Have Shown

The idea that grains are the main cause for allergic food reactions may not be entirely true.

As noted by the Veterinary Dermatology, it was discovered that corn, a grain that is found in many cat foods was in fact far from being the cause of many food allergies.

A study showed how only 4 out of 56 cats tested suffered from allergy-related issues due to corn. It was noted that the majority of the allergic reactions came from beef, dairy or fish.

In another study by Cummings Veterinary Medical Center at Tufts University, they discovered information that was quite interesting. While researching on the nutrient information in 77 dry cat diets, 42 diets contained grain and 35 diets were grain-free.

  • Some diets claiming to be grain-free as a matter of fact had some grain inside it.
  • The average grain-free diet had lower amounts of carbohydrates than grain-containing diets. However, there were also grain-free diets with similar or higher amounts of carbohydrates than those with grains.
  • Poultry, egg, and fish continued to be the most commonly sourced animal sources of protein.
  • In grain-free diets, exotic meats such as bison or rabbit were found.
  • Also, the calories were almost similar in both the diets.

Final Remarks

The best place to start in choosing grain-free cat food is a high-quality formula made with premium animal proteins as the main ingredients.

From there, you can choose a specific type of protein according to your cat’s preferences or choose a multiple-protein recipe. Just make sure it contains adequate levels of protein and fat with minimal carbohydrate content.

Your cat deserves the best, and that means a healthy, high-quality cat food. If you’re not sure where to start, try one of our top picks reviewed above!
