Grain Free Cat Food - All You Need to Know and More!

Paleo, gluten-free, vegan and keto are all diet trends that have made a mark in health and food industries. And similar to these trends, we as cat-owners have also seen our share of feline diet trends. One such recent movement would be the grain-free cat food trend.

What is this grain-free trend that is so popular? Is it another dietary gimmick? Or is it founded on solid studies? You may also be wondering if it is suitable for your cat and whether the ingredients involved are suitable to your cat’s palate. If you have come across grain-free cat food and are considering its pros and cons, read on.

What is Grain Free Cat Food?

If you are like any cat owner who adores their felines, you would be familiar with the process of choosing the right food and diet for your cat. 

It is often an arduous and repetitive task of testing new and different ingredients. Until you stumble upon the one that is beneficial and enjoyable to your kitty.

What is the difference between your regular cat food and the grain-free food that has caught your eyes? 

In your average cat food, you will find a form of protein, vegetable, a good dose of vitamins, micro nutrients and grains. These grains may come in the form of rice, oats, barley or wheat and they make for a good filler in these products.

Grain-free cat food is basically all the same ingredients as normal pet food, minus the grains.

This then begs the question: where will my cat get its carbohydrate? 

Well grains are not the only carbs you will find your cat enjoying and is beneficial to its health. Most grain-free cat food will replace grains with fillers such as potato or beans, ensuring that your cat still gets its carbs.

With that in mind, it is still important that you read and observe the contents of products you purchase. As many will claim grain-free in their manufacturing process but not all are free of grain products.

What is the Advantage of Grain Free Cat Food?

The general health claim of grain-free cat food is that it is much closer with what a feline would consume naturally. 

As most wild cats would not have access to any form of grain, grain is not an integral part of their dietary intakes in the first place.

This then brings up the issue with carbohydrates again. 

“Where will my cat get carbs if they do not eat grains?” is the common question. 

To answer that, we have to establish two important points here which are:

1. There is more than one source of carbohydrate

Your cat can derive carbohydrates from plenty of other sources such as potatoes or peas.

Some pet owners even offer corn.

2. Your cat does not need energy from carbohydrates

    Did you know that your cat does not actually derive its energy from carbohydrates?

    This will come as a surprise for most as we commonly understand that our energy comes from carbohydrates. 

    Well your little feline’s biology is much different than us humans. Cats are known as “obligate carnivores” which means they derive their energy from proteins instead.

    A simple observation of their wild and larger counterparts will shed light on this. Most larger cats such as lions or tigers hunt and consume only meat. You won’t find them being fed with any other food save for meat. 

    It is for this very same reasoning that most claim that a grain-free diet is much closer to your cat’s natural diet. 

    Of course there is also the low chance that if your cat has grain allergies, a grain-free diet would do it well. It is however very slim that your cat would have such allergies. Studies have shown that grain allergies are quite rare, at best, amongst cats.

    Are grain free foods bad for cats?

    As wonderful as providing a close-to-natural diet to your cat may sound, there may be some down sides to consider when going grain-free. Among the problems your cat may face or eventually face are:

    1. Protein as the primary content 

      First and foremost, grain-free cat food will place protein as a primary content in its production. This means that there is a higher amount of meat compared to your regular cat food. 

      Though this may sound like a good thing now that you understand that your cat is an obligate carnivore, there is a danger to it.

      2. More fat content

      Higher quantities of protein and meat also means more fat content. 

      This may seem harmless at first but high fat diets have been known to cause deaths in cats. This happens quite commonly with grain-free food because there is a tendency to overfeed your cat.

      Overfeeding your cat with more fat content per day than per its requirement can be fatal. 

      This applies to most nutrients required by your cat which is why it is crucial for pet owners to consult the nutritional content and also your vet on how much should be given to your cat.

      The second issue may not directly affect your cat as it is more financially-related. 

      Grain-free cat foods are typically more expensive than regular cat food. Owners may be tempted to give this dietary direction a try but may eventually be put off with its cost.

      Should Cats Eat Grain Free?

      There really is no necessity for cats to eat grain free. All studies that have been carried out have shown that there is no such need and no significant pros and cons in going grain free.

      The decision at the end of the day will really depend on the owner and the cat’s preference. Here are some things you would consider when weighing the pros and cons of grain free cat food for your cat.

      Does your cat have grain allergies? 

      As we have mentioned above, grain allergies are extremely rare among cats. If however, your cat does develop allergies towards grains, then yes, going grain free would do your feline much good.

      Do you personally prefer a grain free diet? 

      Perhaps you practice a paleo diet and would like to give your cat similar dietary systems. There is no harm trying that. 

      We do advice that your cat’s food be prepared separately and to observe your cat’s transition as well.

      Aside from the above, there is no significant good or bad when it comes grain free cat foods.

      As we have always said, make it a point to study and consult your veterinarian prior to transitioning your cat to a new diet.

      How to Transition My Cat to A Grain Free Diet?

      Always do your research beforehand as each cat is different and may have different needs. 

      If you do make the change towards a grain free diet for your feline friend, we recommend you pace the transition. It is best to take your time and let your cat adapt to the new diet. Do not rush your cat or force it to go cold turkey on its previous diet. 

      A slow and controlled transition will ensure that your cat’s digestive system has ample time to adapt.

      Always observe to see if your cat is responding well, or not, to the grain-free food.
