How to Read Cat Food Labels: 5 Common Traps Cat Parents Fall Into

October 6, 2026Krzysztof M.

Every conscious cat parent wants the very best for their feline friend. However, a visit to the pet store and a glance at the colorful cat food packaging often ends in a headache. Manufacturers compete with catchy slogans, but the real story of whether the food is healthy is hidden on the back of the packaging—in the fine print of the ingredients list.

To help you make the best choices for your cat's health, we have compiled a list of the 5 most common traps hidden on labels.


1. The Trap: "Meat and animal derivatives"

This is one of the most common and deceptive phrases. When you see "meat and animal derivatives" on a label, you don't really know what is inside. These are often cheap slaughterhouse scraps: beaks, claws, cartilage, and feathers, which have negligible nutritional value.

How it should be: The ingredient list should precisely state the type and amount of meat. At PurryON, we focus on full transparency: we use only clear protein sources. Our food contains a solid 38% meat (chicken or herring), including highly digestible hydrolyzed protein.

2. The Trap: The Magic 4%

Many brands tempt buyers with a huge "With Beef" or "With Salmon" label. By law, for a manufacturer to put such a claim on the front, the recipe only needs to contain a mere 4% of that specific flavor! The rest is often a mix of the cheapest, anonymous meats and fillers. Choose foods where the main meat ingredient forms a solid base of the recipe, not just a flavor additive.

3. The Trap: Ingredient Splitting

Ingredients on a label are listed in descending order by weight. Producers of cheap foods have found a clever way to make meat appear first on the list—they "split" grains into several different items. Instead of one large portion of corn, you will find "corn flour," "corn gluten," and "corn meal" in the ingredients. If added together, grains, not meat, would turn out to be the main ingredient of the diet!

4. The Trap: Artificial Colors and Hidden Sugars

Your cat does not care if their kibble is colorful—dyes are only there to catch your eye. Worse yet, sugar or caramel is added to many cheaper foods to improve their appearance and addict the cat to the taste. Cats lack sweet taste receptors, and sugar in their diet is a direct path to obesity and diabetes.

5. The Trap: Lack of Key Additives

Good meat is the foundation, but a cat also needs functional additives. Look for Taurine (essential for the heart and vision), prebiotics (supporting immunity), and vitamins in the ingredients.


The Verdict

Reading labels doesn't have to be difficult if you know what to look for. Look for foods with a short, transparent ingredient list, high content of specific meat, and no unnecessary fillers.

This is exactly the mindset behind PurryON—a grain-free food with no secrets. Instead of cheap fillers, we used highly digestible potatoes and tapioca, and enriched the recipe with essential taurine (1400 mg/kg) and prebiotics.
