Why Low Carb Cat Food?

Speaking of a human health, the diet is a very controversial issue. Whether it’s a protein-rich or a carb one, there are many theories to follow.

However, the body of your feline works absolutely differently and needs a special approach. Naturally, fluffy cats are predators, which basically eat protein-based food, so that the ratio between proteins and carbs they consume in nature is huge. This is the essential need of their bodies. Protein is what they strive for to have their organisms function well.

So, when it comes to your furry pet’s diet, the choice of food is obvious and unanimous.

The first and main factor is the structure of their digestive system itself, which is built to quickly break down protein. Your cute and fluffy cats are created to eat other animals, like mice. There’s no way a cat would eat grass in wild nature. Their physical needs desire flesh and blood to acquire essential for living nutrients.

Eating a low-carb diet is totally beneficial for a cat’s health. It provides the growth of muscle mass and overall development.

It also helps to keep a normal weight, which is the key to longevity. Otherwise, there is always a risk of aged cats’ diabetes. If you choose a high protein diet, there’s no need to worry. The main goal of low-carb cat food is to maintain a normal weight for your pet. If weight loss is the primary and the only goal for you – please read a guide with the best diet cat food written by Kimberly K. Baumgart RVT, LVT.

Maybe you are still not sure, whether this type of diet is suitable for the lovely kitten. After thorough research and considering tones of opinions, I’ve finally got something to reassure you that a low-carb diet is worth it.

Benefits of Low Carb Cat Diet

First of all, it’s the boost of energy. Proteins are easily digested so that your lively cat shouldn’t sit still for a long time and gain weight. They become more active and energetic.

The next vital thing is the absence of digestion system problems. Carbohydrates sometimes may cause diarrhea, vomiting, gases, and overall bad condition. The risk of diabetes is also caused by carbs, specifically by a high level of sugar that transfers into the blood. That’s why giving cats the food they are created to eat is the key to a truly healthy pet.

Absorbed fats lead to high-quality fur and perfect skin. It’s totally amazing to pet your fluffy feline, which has thick fur with no hairballs. There’s no need to clean the apartment 24/7, as your cat doesn’t shed a lot. The risk of other illnesses is decreased too. If a cat eats the same food as it would do in its natural environment, you shouldn’t worry about any illnesses or inflammations. Getting all the needed components of a cat’s organism will be absolutely fine. Obesity won’t come.

The reason for gaining weight is the lack of protein in each meal. So that the pet needs to overeat to get the necessary amount of essential elements.

It’s obvious, that before switching to another diet type it’s necessary to consult the vet. Of course, every cat’s organism is special and you need to keep balance in proteins, fats, carbs, and moisture.

Summing up all the facts that were mentioned, you may be sure that a low-carb diet is definitely beneficial for a lovely pet’s health. It may bring more joy and energy in a kitten’s life and ensure longevity.

Frequently Asked Questions

What is a low carb cat food?

Low carb cat food contains less carbohydrates than any other type of cat’s product. It means that the percentage of carbs are lower than the one of protein and fat. It’s not necessary know a lot to detect this kind of meal. Just look at the sticker and you’ll see the ratio between all ingredients. Low carb food usually contains less than 30% of carbs in it. However, many companies are not likely to put this information on the sticker so it’s possible learn how to do it yourself.

How to calculate carbs level in cat food?

If the manufacturer didn’t mention the amount of carbs in the product, anyone can easily do it. First of all you have to find out the ratio among all other ingredients. It’s written at the sticker. Just add up all the ingredients in percentage, wet product example: Protein 10.0% + Fat 9% + Fiber 1.5% + Moisture 78.0%=98.5. That means there’s 1,5% of carbs in it. Do exactly the same procedure with dry product and figure out the real numbers.

How to find out if the food is a low carb high protein one?

It might be a complicated question for those who’s just got a cat. The only way is to read the list of ingredients. However it’s also necessary to understand what exactly you are looking for there. Low carb dry food means there’s no more than 30% of carbohydrates in it. Commonly used carbs are wheat, corn and soy. The protein must be animal-based as it is the only one which your carnivore can digest. So find if the source of protein is from meat or fish. There’s always a list of components in percentage. If the choice is a wet type of food, there’s another ratio and the ideal percentage is like this: protein 12.0%, crude fat 2.0%, crude fiber 0.2% and moisture 83%.

Does my cat need a low carb diet?

Many cats quickly become obese if the type of food is not suitable for them. However, the owners start worrying about it only when they see the consequences of bad feeding. It may result in diabetes and other health problems. If the feline friend has such ones, it’s good to take care of choosing the right food option. If there are no vivid problems and the furry cat is absolutely happy, then it is all up to you. There is no urgent need to switch if they are doing okay. If you want to prevent any health issues and worry about it beforehand, you can choose this type of diet and be sure, that balanced food is just what the doctor ordered. If the cat has some health troubles, it’s better to start choosing something else instead of cat’s usual product. Besides, it’s preferable to consult a personal vet instead of making decisions by yourself. Just to be on the safe side!

How much low carb food can a cat eat per day?

Of course it depends on the cat’s age, so you have to check it out whether the food is suitable for kittens, for adults or for all life stages. In general, an adult cat will eat from 50-80 grams of dry food and from 170-210 grams of wet one. If you are having a little kitten, it will consume from 30-65 grams of dry product and approximately 170 of wet one. It’s individual so just try it out and see how your cat is feeling. If it is energetic, healthy and don’t beg human’s food, then be sure that you are doing everything right.

What low carb high protein wet food to choose for diabetic cats?

Diabetes diagnosis is not a disaster, as there are plenty of solutions to it. As a rule, wet food is better than dry one because it makes your cat full enough. It also has less grains, tretches, and the moisture don’t make them thirsty. Diabetic cat food should definitely contain much protein and less than 10% of carbs. There are even specially designed foods for diabetic cats. So the key factor is to look for a wet food, which contains more than 10-12% of protein. The best one is also with an option specially for diabetic cats. Their formula helps to keep blood sugar stable and has low calorie.

Buyers Guide For Best Low Carb High Protein Food

Our lovely cats need special care and perfectly chosen type of food. No matter whether you have a kitten or an adult cat, it’s totally necessary to know which ingredients are essential for its well-being. There are many tricks sellers use to lure you into this world of cat foods. However, it’s obvious that it is you who need to know what’s best for the cat. I know, once you get to the shop where there are many options, you feel like a kid in a candy store. Seeing all catching commercials on TV, perfectly looking packages at the store you might be confused. Some brands have such an appealing label, that people want to trust it automatically. I prepared a guide to choosing the top low carb food for a cat.

List of Ingredients

One of the most important parts is reading the list of ingredients. You don’t need any special knowledge. All of them are listed in decreasing order. So, you already know that the most important thing is the amount of protein, as cats are meat eaters. Then look for chicken or fish first. Then quickly look through the list and if you find such components as vitamins, minerals or amino acids it’s more likely a high-quality product.


As you are looking for a protein-rich food, it’s important to know the needed amount in a package. Only some manufacturers skip this info, but almost all of them do mention the ratio. If a dry food has more than 30% of protein it may be counted as a good one. Foods with 40% of protein are way to go.

Talking about wet high protein food the numbers are different. There’s a moisture in them, which ranks first in percentage. That’s why the percentage of proteins in such kind of food is lower and should be higher than 10-12%. If it does, then you found a good one!

Plant proteins

There’s nothing life-threatening in a plant protein. However, you should be attentive that the product must consist of mostly animal source of protein. Predators, this is who our kittens are, do not consume plant protein in a wild nature. That’s why their organism digests animal based nutrients better. Nevertheless, if you found the food with decent price and ingredients (but containing some plant proteins) – there’s nothing crucial in it. Just take it with no worries.

Things to avoid

Many sellers are focused on meeting every cat’s needs. That is why they care about too sensitive furry friends and make the food smooth enough and easy to chew. If your cat is not the one, don’t think a lot about the food texture. However, if the cat’s digestive system is delicate, you’d better choose special food. Just to be on the safe side. Usually, manufacturers white down on package, that the product is grain free. Some reviewers text, that the product might contain bones. Then, read some reviews as well before buying. It is also helpful to consult your vet in case of any vivid problems.

The range of usage

There are many products which are designed specially for kittens. Other ones are developed for pregnant cats. Most of them are created for adult cats. It’s one of the key factors for adjusting the cat to this or that type of food. Each product has developed to influence positively on the fluffy cat’s health. Some of them are focused on a digestive system, other ones on skin and fur. There are foods for making urine and bladder work well. That is why something that may be beneficial for adult cats, may be super harmful for kittens. Then, while choosing the product, try not to look only at its tastes and package varieties, but also at range of usage.

Cat’s health condition

This factor also effects the choice of nutrition. If the cat is active, friendly and has a lot of energy. You don’t notice anything strange in its behavior. If the cat doesn’t beg your own food, probably, there is nothing to worry about. In such case, it’s possible to choose any type of food and be happy. Otherwise, if you are not sure that the pet is doing alright. If you notice that it may throw up from time to time. Some people say that their cat has vomiting. Maybe its runny stools depend on the type of food it eats. If you hear the cat pooping quite often, it might be also not a very good sign. In this situation, the best option is to consult a vet. Only then you’ll know what type of food is needed.

Energy components in food

This factor depends on your cat’s activity. If you are having an indoor cat, it doesn’t need much energy to spend on. This furry pet needs only normal energy content food to keep it active for cat’s everyday routine. However, if the cat walks outdoors, it’s better to boost pet’s energy with the type of food, that has more such kind of components.

The price

Having a cat means spending lots of money on it. That’s why it’s better to be prepared for it. They do need a high-quality food and we are responsible for it. Of course, there are many super cheap options and you may save your money. It looks rationally, but wouldn’t you agree that it’s not fair.

There’s a wide range of products you can choose to feed your pet. Sometimes the price is unreasonable and it’s not worth paying. Many products are top-rated ones and they are good, but quite expensive. There is always an alternative. There’s always an opportunity to find less popular brand or not that good product recipe, but for suitable price for you.

It is highly important to know what type of nutrition to choose for your lovely furry cat. That’s why I’ve done a thorough analysis of loads of products and owner’s reviews to prepare a decent list of foods. I hope this information will be useful to you! Besides, you are more than welcome to comment on your favorite product and share the experience. To know other opinions comes always in handy.
