Grain Free Cat Food 101

The hype for grain-free diet plans for humans continues.

Initially adopted by those who have been diagnosed with celiac disease – a disease characterized by difficulty in digesting food due to hypersensitivity to gluten- this diet plan, later on, became widespread and is now used as a means to improve ones health.

As for our pet food manufacturers, they cannot help but join the bandwagon.

If you are looking for grain-free cat foods, you are most probably someone who has tried this type of diet yourself. You might also be someone who firmly believes that your cat needs a high protein, low carb diet given that they are biological meat-eaters.

Or maybe, you are just one of the pet owners who just thinks this is a good choice for your hypersensitive cat. Regardless of your reasons, one thing is for sure.

We know for a fact that you, as a loving pet parent, value your cat’s health above all. However, as a pet parent who has great concern over his or feline’s well being, it is best that you understand what grain free cat food is all about.

What is Grain-Free Cat Food?

Grain free cat food, as the name suggests, is a special type of cat food that is devoid of grains.

Grains, which include wheat, corn, and oats, are a staple in most traditional diets (both in the human and cat food realm). While this serves as an excellent source of energy, it contains gluten that can cause intolerances or allergies. It also contains carbohydrates that, when taken in high levels, can lead to unhealthy weight gain.

Did you know?

Benefits of Grain Free Cat Food

Grain-free cat foods may not be a type of diet plan that will work for all kinds of cats. Nonetheless, a good number of pet parents and their four-legged pals would attest to its benefits.

Remember, however, that choosing what to feed your furry pals is crucial since it involves their health. Before deciding on what food or type of diet to give your cat, talking to your veterinarian is always recommended

1. High-Quality Ingredients

Regular cat food would often contain wheat, corn, and grain. Often used as fillers, these ingredients are relatively cheap and just increase the foods’ carbohydrate content.

Grain-free foods for felines (whether a wet or dry cat food), on the other hand, often incorporate wholesome ingredients into the mix like real meat and vegetables.

Vitamins and minerals are also added, with some brands adding Omega-3 fatty acids or Omega-6 fatty acids, to make sure that your cat’s diet is complete and balanced. Also, many are made without additives or artificial preservatives.

2. Made to Resemble the Natural Cat’s Diet

A cat’s diet, biologically, is made up of 55% protein. Generally, you will find that most grain-free cat foods try to offer that much protein content. Generous amounts of animal protein like chicken, beef, and fish are usually seen in both wet and dry cat food that are free of grains.

3. It is Good For Cats with Grain or Gluten Allergies

While the number of cats with this condition is significantly few, we cannot ignore the fact that this is the actual reason why this type of diet came about. Just keep in mind that grains and gluten are two different things.

Grain-Free vs Gluten-Free Cat Food

Gluten is a type of protein that can be found in specific kinds of grains like rye, wheat, and barley. Take note that not all grains contain gluten. To cut the story short, a grain-free diet will always be gluten-free while cat food with zero gluten may not be free of grains.

What to Look for in Grain Free Cat Foods?

When looking for a grain free cat food for your pet, aside from making sure that it is devoid of grains, it is also best to keep an eye on these features.

Provides Complete and Balanced Nutrition what to look for

If you want your cat to enjoy a nutritious and balanced diet, then make sure that the cat food you are planning to buy meets the requirements of AAFCO (Association of American Feed Control Officials).

It helps to know as well that your cat should be enjoying at least 35 to 40% protein. If yous cat has dry, dull, itchy, and brittle skin and haircoat, cat food that contains sufficient amounts of fatty acids can help prevent this condition (often experienced by cats with allergies).

Appropriate for your Cat’s Life Stage

When it comes to protein, kittens evidently require 1.5 more protein than puppies do. Adults cats need two or three times more protein compared to adult dogs.

If we compare kittens to adult cats, kittens, in order to grow and develop normally, will need food that has greater nutritional value.

Make Sure to Get Quality Grain Free Cat Food with these Tips

Since the options for grain free cat food are plenty, and many (if not all) brands would advertise themselves as trustworthy, taking these steps would guarantee that you are actually getting what your cat really needs. So, read on.

1. Talk to Your Veterinarian

We know that we have mentioned this several times. It might sound redundant, but if you truly and sincerely value your cat’s health, then you would understand.

Out of your busy schedule, take the time to set an appointment with your vet and discuss your feline’s condition. It is best, as well, to listen to their recommendations.

2. Read the Labels and Check the Ingredients

A brand would often promote what is good about their products. But, have you ever seen a brand pointing out their flaws as well?

We all know the answer to that. So, aside from ensuring that the cat food that you are planning to buy is AAFCO- approved and offers complete and balanced nutrition as well as wholesome ingredients, read its labels and keep an eye on its ingredients. While it is grain free, some might in fact contain added ingredients that might be harmful to your cat.

3. Do Your Own Research

Ever encountered words or phrases on the labels that you do not really understand?

Once you scan the labels and ingredients, you will soon realize that there are lots that you do not completely comprehend. So, take your time to check online, or better yet, ask your vet.


Common Misconceptions on Grain-Free Cat Food Debunked

While this type of diet is popular nowadays, cats adopting it remains controversial. Many also choose this for the wrong reasons. So, allow us to enlighten you in one way or another by discussing the common misconceptions on grain-free cat food.

1. Grain-Free Cat Foods are Carb Free

Known as obligate carnivores, a cat’s diet, given their predatory nature, has to be somewhat similar to what their ancestors eat or a wild cat’s diet – that is a diet high in protein, low in carbohydrates. This is necessary in order for them to achieve optimal gut health.

This holds true. And you can expect holistic veterinarians, not to mention the increasing number of cat owners, to nod in approval.

Enter grain-free cat food. A good number of pet parents buy this mainly because they believe that this contains zero carbohydrates. Little do they know, that while this is grain-free, many of this type of pet food contains either the same level or even higher levels of carbohydrates than those made with grains.

Check the ingredients. Aside from containing high levels of protein and some amount of fatty acids, grain-free cat foods are often formulated with potatoes, sweet potatoes, tapioca, peas, and lentils – all of which contain carbohydrates.

2. Grain Free Diets Help Control Cat Weight

One of our solutions to weight loss is by entering into grain-free diet plans. Since it works for humans, we believe that the same type of diet will work with cats. While this principle might hold some truth, it’s somewhat different when it comes to cat food.

Grain-free cat foods may be devoid of grains, always high in protein, and may at times contain essential fatty acids, but it will often contain carbohydrates. Thus, we cannot help but reiterate the importance of checking the ingredients.

Also, weight gain in cats can be caused by a number of factors, You might be feeding your cats grain-free foods, but then decide to feed it freely – or give it whenever they please – then, you will, more often than not, end up with an overweight cat.

3. Grain Free Cat Foods Help Alleviate Food Allergies

By now, some of you might be shaking your heads in disapproval. But hear us out.

It is true that a few cats suffer from allergies caused by grains. However, this is rare. Articles like the one released by VCA Hospitals and PetMD confirm that when it comes to our feline friends, their itchy skin issues and gastrointestinal upsets are often related to allergic reactions to common proteins like poultry, beef, and fish.

We know we have mentioned this before, but, here is where your veterinarian’s advice will play a critical role. Your vet is your best bet when it comes to finding out what is causing your cat’s allergies. They are also capable of recommending the best diet to address it.

final thoughts


Fact – grain-free cat foods can indeed be beneficial as long as it is given to the cat for the right reasons. Like all other diet plans available in the market, it is not something that will work for each and every cat. Remember, that each cat is unique.

Like humans, their tastes, preferences, and personalities differ. The effect of one type of high protein, low carb grain free cat food on one cat may be positive. This, however, does not guarantee that it will work for all or for your cat specifically.

Whether your cat needs it or not would depend on your vet. Add to the equation being meticulous when it comes to checking what your cat is eating, your commitment and love, and you will end up with a happy, energetic and healthy cat.
