What Makes a Good Cat Food?

  Browse categories

There is no shortage of options on the cat food shelf. Today, cat food can be found in supermarkets, pet stores, online shops and countless other places, all promising great taste, premium quality and excellent nutrition. But how can you tell which cat food is actually good?

There is no single answer, because every cat is an individual. However, there are a few key factors worth considering regardless of where the food is purchased. Understanding a little about feline nutrition and how to read ingredient labels can make choosing the right food much easier.

Cats Are Carnivores

Cats are obligate carnivores. In the wild, their diet consists mainly of small prey animals that provide the protein, fat, vitamins and minerals they need.

For this reason, the foundation of a cat's diet should consist of animal-based ingredients. Cats require nutrients such as taurine, an essential amino acid naturally found in animal tissues. Unlike many other animals, cats cannot produce sufficient amounts of taurine on their own.

When comparing different cat foods, one of the first things to look at is how much of the nutritional content comes from animal-based ingredients.

Don't Be Misled by Marketing Terms

An attractive package or persuasive marketing message does not automatically mean a food is high quality. Terms such as "premium", "natural" or "gourmet" may sound impressive, but their meaning can vary significantly between products.

Instead of focusing on marketing claims, turn the package over and take a closer look at the ingredient list and nutritional analysis.

Why the Ingredient List Matters

The ingredient list reveals what a cat food is actually made of. Ingredients are listed in descending order by weight, meaning the ingredients at the top of the list make up the largest portion of the recipe. Since cats are carnivores, animal-based ingredients should appear near the top.

However, there can be major differences in how clearly ingredients are declared. Some products use broad descriptions such as "meat and animal derivatives", leaving consumers with very little information about what the food actually contains. What animal does the meat come from? Is it fresh meat, dried protein or something else entirely?

Many cat owners prefer foods that clearly identify their ingredients and include percentages, such as "fresh chicken 28%" or "dried turkey protein 26%". The more transparent the ingredient list is, the easier it is to evaluate the food's quality and suitability for your cat.

Protein Content Doesn't Tell the Whole Story

A high protein percentage may sound impressive, but the number alone does not tell the full story. It is equally important to consider where that protein comes from.

Two different cat foods may contain nearly the same protein percentage, yet one may obtain most of its protein from animal-based ingredients while the other relies heavily on grains or plant-based sources.

Because cats are carnivores, what matters most is how much of the protein comes from animal sources. This is why protein percentages should always be considered alongside the ingredient list.

Why Choose Grain-Free Cat Food?

Grain-free cat foods have become increasingly popular among cat owners. One reason is the cat's natural diet: cats are carnivores whose bodies are specifically adapted to utilize animal proteins and fats.

Grain-free alone does not automatically make a food high quality, but it does indicate that the recipe is not primarily built around grains such as wheat or corn. Many cat owners prefer foods where animal-based ingredients play the leading role in the recipe.

Sweet Potatoes, Peas and Potatoes in Cat Food

Although cats are carnivores, many cat foods also contain plant-based ingredients. Ingredients such as peas, sweet potatoes and potatoes are common in many high-quality cat foods. They are not included by accident, but serve specific functions in both digestion and food production.

  • Fibre: Plant fibres are not absorbed as nutrients, but they play an important role in digestion. Fibre helps support normal intestinal function, may help prevent constipation and can assist in moving swallowed hair through the digestive tract.
  • Starch: Dry kibble requires starch to maintain its structure. In grain-free recipes, this starch typically comes from ingredients such as peas, sweet potatoes or potatoes instead of grains.

Many quality cat foods also contain small amounts of vegetables, berries or herbs. These ingredients are not intended to replace animal-based ingredients but rather to complement the recipe by providing fibre, vitamins, minerals and natural antioxidants. While cats are carnivores, carefully selected plant ingredients can be a beneficial part of a balanced diet.

Wet Food or Dry Food?

Both wet and dry food have their advantages.

Wet food contains a high amount of moisture, which can help support hydration. Dry food, on the other hand, is convenient to store and easy to portion.

Many cats benefit from a combination feeding approach that includes both wet and dry food. This allows them to enjoy variety while taking advantage of the benefits of both food types. We discuss this topic in more detail in our article "How to Feed an Adult Cat".

Nutrition for Different Life Stages

A cat's nutritional requirements change throughout its life.

Growing kittens need plenty of energy and nutrients to support healthy development. Adult cats have different requirements, and neutered or spayed cats may have lower energy needs than before.

When choosing a cat food, it is important to consider your cat's age, activity level, lifestyle and any special dietary needs.

Good Cat Food Is About the Whole Picture

The best cat food is not necessarily the one with the most attractive packaging or the longest list of marketing claims. Instead, look at the complete picture: the ingredients, the protein sources, the nutritional profile and how well the food suits your individual cat. Once you learn how to read ingredient lists and understand the basics of feline nutrition, making informed choices becomes much easier.

Frequently Asked Questions – Choosing Cat Food

How can I recognize a high-quality cat food?
One of the best ways to evaluate cat food is by reading the ingredient list. Since cats are carnivores, animal-based ingredients should form the foundation of the recipe. The more clearly the ingredients are identified, the easier it is to assess the food's quality and suitability for your cat.
Is grain-free cat food better?
Grain-free alone does not automatically make a cat food higher quality, but many cat owners prefer grain-free recipes because cats are natural carnivores. What matters most is the overall recipe and how much of the nutrition comes from animal-based ingredients.
Why do cat foods contain peas, potatoes or sweet potatoes?
Plant-based ingredients can serve several purposes in cat food. They may provide fibre to support digestion and supply starch, which is needed in the production of dry kibble. In grain-free recipes, starch often comes from ingredients such as peas, potatoes or sweet potatoes instead of grains.
What does it mean that cats are carnivores?
Cats are obligate carnivores, meaning their bodies are designed to utilize animal proteins and fats as their primary source of nutrition. This is why animal-based ingredients should form the foundation of a cat's diet.
Why doesn't the protein percentage tell the whole story?
A protein percentage alone does not reveal where the protein comes from. Two cat foods may contain similar protein levels, while one relies mainly on animal-based ingredients and the other obtains a significant portion of its protein from plant sources. For this reason, it is important to consider both the protein content and the ingredient list.
Should I feed my cat wet food or dry food?
Both wet and dry food have their benefits. Wet food contains a high moisture content, which helps support hydration, while dry food is convenient to store and portion. Many cats benefit from a combination of both.
Do neutered or spayed cats need a special diet?
After neutering or spaying, a cat's energy requirements may decrease while appetite can increase. Many owners therefore choose foods specifically formulated for neutered cats to help support weight management and overall wellbeing.
