High Protein and Low Carbohydrate Cat Food Buyer's Guide

Cat wanting to eat a high protein low carb diet

How much protein does your cat need? How about carbs? It's essential that you know the optimal protein and carb content in your cat's food because this allows you to check the label of the various foods you compare and choose the best one. The ideal content is:

  • Carbohydrates - 2.8 to 12-percent
  • Fat - 22 to 36-percent
  • Protein - 52 to 63-percent

Ideally, your cat's food should be on the lower end of the carbohydrate spectrum because this is where wild cat's diets are. It may not be possible to find these exact ranges, but you should be okay if your cat's food gets close to these ranges. It's also beneficial for a diabetic cat to have this type of diet with low carbohydrates.


Why Feed Your Cat This Type of Diet

By nature, cats are carnivores that ate a mostly protein-based diet with very few carbohydrates. Your cat may be domesticated now, but they still need the higher protein content to support healthy muscle growth and overall development.

Cats also had low carbohydrates in their diet, and it came from the other parts of the animal they ate. You don't see cats in the wild eating fatty or plant-based diets, and carbohydrates lead to weight gain. Feeding your cat lower carbohydrates helps them maintain a healthy weight, and this is especially important as they age or if they're diabetic.

Benefits of Feeding a Low Carbohydrate and High Protein Diet

There are several benefits that come with feeding your cat this type of diet. If you're searching for reasons to make the switch, we invite you to take a look at our list below.

  • Energy Boost - Protein can give your cat a much-needed energy boost that can help to keep them active, even as they age. This can help to keep them lean and at a healthy weight throughout their lives.
  • Fewer Digestive Issues - Your cat's body can't digest higher levels of carbohydrates, and it can lead to things like diarrhea, throwing up, gas, and general discomfort. Feeding them a diet that their body is designed to absorb and use is one way to alleviate these issues.
  • Good Development - Your cat's body needs several key things to develop all of their systems and keep them healthy. Protein ensures healthy muscle growth, fats ensure that your cat's skin and coat and healthy, and fewer carbohydrates ensure that your cat's digestive system will extract as many nutrients as possible.
  • Reduced Blood Sugar Levels - Foods that are carbohydrate-rich can cause your cat's blood sugar levels to spike and stay high. Your cat's body may not be able to handle these spikes, and it can lead to diabetes.

How to Find the Best Food for Your Cat

There are several key things that you want to look for when you start to compare various cat foods. These things will help to ensure that you get a healthy food, and it includes things like:

AAFCO Rating

You want to check your potential cat food on the Association of American Feed Control Officials (AAFCO) rating to see how to compares to their suggested nutrient guidelines. The closer the food is to these guidelines, the better it will be for your cat to eat because it closely mimics a higher protein diet.

Calories per 100 Grams

Along with the nutrient label, your cat's food will have the calories per every 100 grams of food. You want a lower calorie count in the food, because this is usually a good indication of the carbohydrate levels, and too many calories is a fast way for your cat to gain weight.

Controversial Ingredients

Pet food manufacturers can sneak more controversial ingredients into their cat food by hiding it in the middle or near the bottom of the ingredient list to bulk up the formula. These things offer little, or no nutritional value for your cat and they include by-products, meat meals, artificial colors or flavors, soy, corn, wheat, and rendered fats.

First Three Ingredients

Make sure that you take a look at the first three ingredients listed on your cat food's label. These three things will make up the bulk of the cat food formula, and it can give you a good idea on whether or not it's healthier. Ideally, you want meat listed as the first ingredient.

Macronutrient Profiles

The macronutrients in your cat's food include things like the dry-matter basis, caloric basis, and the guaranteed analysis. These things should work to support your cat's body each time they eat it, and they're usually listed separately off to the side of the nutrient label.


Price is going to play a role in which food you ultimately choose because these types of food tend to be slightly more expensive per pound than less healthy foods. It works just like junk food to healthy food for humans. Find a price that's comfortable, and narrow your search down from there to find the best option for your cat and your budget.
