As a responsible cat owner, it’s your duty to spoil your cat with a nutritious and delectable diet. Your cat should have a diet that has all the necessary nutrients needed for her growth and development. Usually, these furry felines don’t require the carbohydrates present in grains; some cats even get serious digestion problems or allergies because of them. This list of best grain-free cat food can be the solution to your problems.

Your cat can be a picky eater. In that case, you have to select the right food with balanced nutrition and taste. You should analyze your cat’s needs and requirements before finalizing the right food for her. Maybe your cat prefers chicken over salmon? Or maybe she needs something that will calm her stomach? 

To answer all the questions related to your cats food, you should know about them first. And, then maybe you’ll realize that a grain-free diet is probably the best diet for your cat. This article contains all you need to know about the best grain free cat food and why should you consider switching your cat’s diet.


Benefits of Grain-Free cat foods

1. Need for protein

Cats are obligate carnivores, which means that your cat needs a diet rich in animal proteins. An ideal diet for cats consists of about 35-45% of protein, a moderate amount of fat, and minimal carbohydrates. While choosing the right food for your feline, the amount of protein plays the most crucial role. This is why people prefer to go for a grain-free diet. Protein is the main ingredient in this diet and it provides adequate nutrients for your cat. 

2. Minimal carbs

As discussed before, your cat’s diet must have low carbs. According to a cat’s ancestral history, carbohydrates were never the primary source of their energy. Carbohydrates found in foods like wheat, barley, rice, and corn, are only a small portion of a cat’s diet. 

Therefore, it is vital to check the carbohydrates level before deciding the best grain-free cat food for you. Ingredients like vegetables like potatoes or peas also increase the carbs even though they’re grain-free. Thus, they should be avoided too.

3. Great for sensitive cats

Grains are listed among common allergens for cats. They can cause itching, disrupted stomach, or other digestive issues. Even if your cat hasn’t been diagnosed by a veterinarian, you can change their diet once you start noticing the symptoms. 

Hence, switching to a grain-free diet might give you a calm and happy cat. And which pet owner doesn’t want that?

FAQs on Grain Free Cat Food

1. What creates a decent grain-free food?

You must make sure that the food you’re offering to your cat is exactly what she needs. One of the most basic points to keep in mind is that the product must follow the nutritional guidelines laid down by the Association of American Feed Control Officials (AAFCO). It is mandatory for all the pet food products to meet these guidelines before they advertise their product as balanced and complete.

The next thing to consider is your cat’s personal taste and preference. Each cat is unique and has their own individual requirements. If you bought what you believe is the highest quality cat food available, your cat may not like it.  

Therefore, you have to select a flavor that she’ll like. Fortunately, the cat food market is filled with numerous flavors to suit the needs of every picky cat. Hence, it’s better to follow the nutritional requirements given by your veterinarian, and then select a flavor your cat will love to eat.

2. How to soothe your cat’s upset stomach?

There are various reasons behind a cat getting an upset stomach. It can range from not liking the food to eating it too fast because they liked it too much. If your cat constantly gets upset stomach signs like regurgitation or diarrhea. Then you must go to a veterinarian and follow certain steps to take care of your sensitive cat.

Always keep track of what cat your cat is eating. If you have just gotten a new cat, then make sure to know about her food habits before you make any drastic changes in her diet. It’s also important to know about the frequency and timings of her meals. 

If your cat is not new, then make sure that you are aware of someone else feeding her something. You need to check her diet thoroughly before going to a veterinarian to know what food she is sensitive to.

If you have bought or adopted a cat, then the transition to a new diet should always be slow and steady. It’s best to continue the previous diet for one to two weeks, slowly making small changes to her diet. Any sudden change will cause distress and she will most likely throw up her food.

If you need to make that transition in her diet more quickly, replace the original meal with some boiled white rice. Keep adding the new diet supplement after every three to four days. You can also ask your veterinarian to suggest some feline probiotics to make this transition more smooth and quick.

There are some signs that are more than the usual “upset stomach”. If your cat shows any of these signs, it’s best to take her to a professional as soon as you can.

  • If you see blood in her stool.
  • She experiences loose stool quite often.
  • There’s a change in her appetite.
  • She no longer gets thirsty.
  • If you notice her stool getting darker.
  • Constant vomiting.

Before changing your cat’s diet, it is always advisable to check with your veterinarian if that diet is suitable for your cat. You can always ask for their recommendations to find the best food for your pet.

3. How much should you feed your cat?

The quantity of food that should be fed to your pet depends on various factors –

Physical Activity 

The amount of food you give to your cat should always depend on the kind of lifestyle she follows. If your cat is rather sedentary, then it’s best for you to calculate and track her calorie intake. On the other hand, if she exercises a little every day, you can go easy on her meals.

Current Weight

If your cat is healthy and lean, you can just follow the feeding instructions given on the food label but if she’s overweight, you should reduce her calorie intake.

Life Stage

Kittens, as well as the developing indoor cats, require more nutrition and food as compared to adults and seniors. Those senior cats who lead a sedentary life need less quantity of food than adults. You have to make sure that you don’t overfeed them.

Stress Levels

If your cat has recently experienced something that may have caused stress to her, for instance, if you moved to a new place or she got pregnant, then you need to give her more food than her usual quantity. 

Once the situation has calmed down, you can follow the feeding instructions given by your veterinarian.

4. How to know if your cat is overweight or obese?

Indoor cats are more likely to get overweight or obese as compared to outdoor cats. This is because they get little to no physical activity in their daily lifestyle which is why the amount of calorie burnt is very less. 

Cats who are overweight are in the constant risk of developing a cardiovascular problem, joints problem, or other life-threatening diseases like, type 2 diabetes, Mellitus, respiratory disease, osteoarthritis, and non-allergic skin problems.

Now, if you’re confused about whether your cat is overweight or obese, the following points may help you.


If your cat has become sedentary over time then her weight might be an issue. You should take your cat to a skilled veterinarian whenever you notice something has changed from her usual lifestyle. It’s possible that her weight might not be the only reason for her sedentary nature, which is why you should always consult your vet before making any change in your cat’s diet.

Sounds by cat

You can also notice the way your cat walks or jumps off from higher places to understand if she needs fewer calories in her diet. Cats are usually very silent and stealthy. Therefore, when you begin hearing constant thuds whenever your cat jumps, it might be a good sign to start cutting off some calories from her food. 

This still doesn’t permit you to make any drastic changes in her diet. Any change you want to make should be slow and periodical to prevent any signs of an upset stomach.


This may sound strange but gently squeeze your cat to know if she’s overweight or obese. If you are able to feel her ribs without much struggle, she’s fine and you can continue with the feeding instructions given on the food label. 

The more noticeable these signs are, the more obese your cat is. This doesn’t mean you have to give her bland low-calorie food; there are many grain-free low-calorie cat foods in this list with great taste and flavor.

When you see your cat gaining weight regularly, you should definitely take her to a vet as this can be very destructive for her overall health.
