What Ingredients Should Be In Cat Food? 5 Ingredients To Look For

What Ingredients Should Be In Cat Food?

All cat parents know how challenging it can be to select the best food for your feline friend. Whether you are buying for the first time or looking to change the food’s brand, picking the right one isn’t a walk in the park.

The most important thing to check while buying cat food (dry, wet, or semi-moist) is the quality and quantity of ingredients. Don’t worry; you aren’t alone in this challenge. This guide will explain what ingredients should be present in cat food and the ones you must avoid. So, let’s begin our journey of finding feline’s dietary excellence.

Ingredients Should Be In Cat Food

Important Cat Food Ingredients That Must be in Cat Food


Proteins are vital for the overall health and functioning of cats. They provide the necessary amino acids that cats cannot synthesize on their own. These amino acids are essential for muscle growth, tissue repair, and immune system support.

While cats primarily use fat for energy, proteins can also serve as an energy source, especially during periods of fasting or insufficient calorie intake. The quality of protein in cat food is crucial. High-quality proteins contain all the essential amino acids in the right proportions for cats. Animal-based proteins usually offer this complete amino acid profile.

High-Quality Protein Sources for Cats

  • Chicken
  • Fish
  • Turkey
  • Egg
  • Duck
  • Lamb
  • Beef

Recommended Protein Quantity

The quantity of protein in cat food can vary, but adult cats typically require a diet with at least 26% protein on a dry matter basis, according to the Association of American Feed Control Officials (AAFCO) guidelines. For kittens, pregnant or nursing cats, the requirement is higher, often around 30% protein on a dry matter basis. It’s important to note that the quality of the protein is just as important as the quantity.

Role of Taurine in Cat Food

Taurine is an essential amino acid for cats, crucial for maintaining their heart health, vision, and reproductive functions. Unlike many other mammals, cats cannot synthesize taurine in their bodies and must obtain it through their diet. A deficiency in taurine can lead to serious health issues, including heart disease (dilated cardiomyopathy) and vision problems. Therefore, ensuring a sufficient taurine content in cat food is vital for their overall well-being.


Fats & Oils

Benefits: Fats and oils play a significant role in cat food, serving as the primary source of energy for cats. They are also essential for the absorption of fat-soluble vitamins (A, D, E, and K) and contribute to the palatability and texture of the food. Moreover, certain fats are crucial for maintaining healthy skin and coat. The types of fats typically found in cat food include animal fats (like chicken or fish oil) and plant-based oils (such as flaxseed or sunflower oil).

Sources: Animal fats are highly palatable for cats and provide them with arachidonic acid, an essential fatty acid that cats cannot produce on their own. Fish oil is a valuable source of omega-3 fatty acids, which can aid in reducing inflammation and supporting brain health. Plant-based oils, while not as palatable to cats, can still be beneficial, particularly for providing omega-6 fatty acids.

Quantity: The amount of fat in cat food can vary, but generally, adult cat food should contain about 9% to 15% fat on a dry matter basis, as recommended by the AAFCO. For growing kittens, pregnant or nursing cats, the fat content may be higher to meet their increased energy needs. It’s important to balance the fat content in cat food to prevent obesity, which can lead to health problems, while still ensuring enough energy and essential fatty acids for optimal health.

Importance of Fiber in Cat Food

Fiber is crucial for a cat’s digestive health, aiding in regulating bowel movements and managing weight. It also helps in controlling hairballs and can be important for blood sugar regulation in diabetic cats.

Types of Fiber in Cat Food

Cat foods include soluble fiber (like beet pulp) for digestion regulation and insoluble fiber (such as cellulose) for intestinal movement. These fibers are key for maintaining digestive health.

Recommended Fiber Content in Cat Food

The optimal fiber content in cat food varies based on the cat’s health, age, and specific dietary needs. Generally, commercial cat foods contain between 1% to 10% fiber on a dry matter basis. A balanced amount is key; too little fiber can lead to digestive issues, while too much can reduce the digestibility and absorption of essential nutrients. For specific dietary needs, such as weight management or hairball control, diets may have modified fiber contents tailored to these requirements.


Vitamins and Minerals

Vitamins and minerals in cat food are essential for maintaining overall health and supporting various bodily functions. Vitamins, such as A, D, E, and the B-complex, play roles in vision, bone health, antioxidant functions, and energy metabolism. Minerals like calcium, phosphorus, and magnesium are vital for bone structure, nerve function, and cellular processes.

Trace elements like iron, zinc, and selenium are crucial in smaller amounts for blood health, immune function, and antioxidant defense. A balanced cat food formulation ensures these nutrients are provided in the correct proportions to support a cat’s overall health and vitality.

Vitamins and Minerals


Carbohydrates in cat food, while not essential, provide a readily available energy source and contribute to the kibble’s structure and palatability. Common sources include grains, such as rice or corn, and legumes like peas. They also play a role in digestive health, primarily through the fiber they offer, which can aid in bowel regularity and weight management.

In terms of quantity, there is no specific requirement for carbohydrates in a cat’s diet, but many commercial cat foods contain between 20-40% carbohydrates on a dry matter basis. Care should be taken to ensure that carbohydrate levels are not excessively high, as cats are obligate carnivores, and high carbohydrate diets can lead to health issues like obesity and diabetes. The focus should be on complex carbohydrates for sustained energy release without significant blood sugar spikes.


Ingredients to Avoid in Cat Food

  • Animal By-Products: These are often lower-quality protein sources, including organs and parts not typically consumed by humans. While they can provide nutrients, their quality and digestibility can vary greatly.
  • Grains and Fillers: Grains like corn and wheat are used to add bulk and are less nutritionally valuable for cats, who are obligate carnivores. Fillers provide little nutritional value and are often used to reduce manufacturing costs.
  • Artificial Flavors, Colors, and Preservatives: These chemicals are added to improve taste, appearance, and shelf life, but can be unnecessary and potentially harmful, leading to allergic reactions or health issues in cats.
  • Rendered Fats: Often used to enhance flavor, rendered fats can be sourced from unspecified animals, raising concerns about quality and the potential for contamination with harmful substances.
  • Added Sugar: While added to increase palatability, sugar is not a natural part of a cat’s diet and can contribute to obesity, dental problems, and potentially diabetes.

Ingredients to Avoid in Cat Food

Wet Cat Food vs. Dry Cat Food: How Ingredients Vary?

Wet cat food typically contains higher moisture content, often around 70-80%, and generally has more animal proteins and fats, making it closer to a cat’s natural diet. On the other hand, dry cat food has a lower moisture content (about 10%), relies more on carbohydrates for structure, and may include more grains and fillers.

The preservation methods also differ: dry food uses low moisture for shelf stability, while wet food is often canned to preserve freshness without artificial preservatives. This difference in composition can affect a cat’s hydration, weight management, and overall health.

Role of Water in Cat Diet: How to fulfill Hydration needs of cats on dry Food?

Water is crucial in a cat’s diet, particularly for kidney and urinary tract health, as cats naturally have a low thirst drive. Cats on a dry food diet may not get enough moisture from their food alone, as dry food typically contains only about 10% water.

To ensure adequate hydration, it’s important to provide constant access to fresh water. Additionally, incorporating wet food into the diet or adding water or broth to dry food can help increase their water intake. Some cats also prefer running water and may drink more from a fountain.

Frequently Asked Questions
