Cat food: how to choose the right diet without falling for misleading claims

Choosing cat food can quickly become a headache when you’re faced with claims such as ‘with salmon’, ‘grain-free’, ‘high in meat’ or ‘premium’. But these promises alone aren’t enough to tell you whether a product is suitable for your pet’s everyday diet. For an adult cat, particularly one that is neutered or prone to food sensitivities, it’s best to check whether the food is complete, look at its ingredients and choose the most practical format for your household.

Common pitfalls when buying cat food

1. Confusing complete food with complementary food

A tin of wet food, a treat or a pouch may sound appetising without being suitable as a meal replacement. The label ‘complete pet food for adult cats’ means the product is formulated to provide a cat’s daily food allowance, in line with the manufacturer’s recommendations. Cat treats, on the other hand, are generally complementary foods.

Catisfactions treats are a good example: they can complement a balanced diet, but shouldn’t replace main meals. Their ingredients include 4% salmon, and each treat is stated to contain fewer than 2 kcal. The amount you give your cat should still fit within their daily food allowance.

2. Relying on the recipe name alone

A salmon cat food pâté doesn’t necessarily contain mostly salmon. In the 400 g AP terrine, fish and fish derivatives make up the relevant ingredient group, with 4% salmon. This proportion allows the product to be labelled ‘contains salmon’, but it doesn’t mean salmon is the main ingredient.

The same caution applies to salmon cat biscuits. Whiskas biscuits for neutered cats state that the brown pieces contain 4% salmon, while cereals appear first on the ingredients list. So it’s best to read the whole label rather than judging by the picture on the pack or the flavour highlighted on the front.

3. Buying a large pack without checking storage requirements

A multipack of cat food can bring down the cost per portion, as long as it suits how much your household actually uses. Once opened, wet food will generally keep in the fridge for 24 to 48 hours, depending on the manufacturer’s instructions. Individual 85 or 100 g pouches make portioning easier and help reduce waste, while a 400 g tin may suit a cat that regularly eats wet food.

What to check before you order

Complete food, age and your cat’s needs

For an adult cat, start by choosing a product clearly labelled complete food. Dietary needs vary depending on age, activity level, weight and whether your cat has been neutered. Food for neutered cats may have a different energy density or recommended portion size, but you should always adjust the amount to your cat’s body condition.

If your cat has a known food sensitivity, check all the protein sources in the recipe. A ‘single-protein’ formula is only useful if its ingredients genuinely suit your needs. If your cat has a reaction to food or a specific health concern, ask your vet for advice.

Moisture and format

Wet cat food, whether pâté or a pouch meal, generally contains much more water than dry food. Recipes in this category often have a moisture content of over 70%. They offer a variety of textures and meals, but need to be kept in the fridge once opened.

Dry cat food is easier to store and portion. You should still always leave fresh water available. The feeding guidelines on the pack are a starting point: adjust them to your cat’s weight, activity level and physical condition.

Ingredients and marketing claims

Ingredients are listed in descending order by weight. Claims such as grain-free, high in protein or premium cat food should be checked against the analytical constituents and full ingredients list.

For example, the Petty Croq.Chat salmon recipe contains 28% dehydrated fish, including 14% tuna and 14% salmon, as well as peas and potato. It’s described as complete food for adult cats, including neutered cats. Even so, you should still check the daily portion and how well your cat tolerates it.

Frequently asked questions about cat food

How much food should you give an adult cat?

The amount depends on your cat’s weight, activity level and age, as well as the format and energy density of the recipe. Check the feeding guide on the packaging, then gradually adjust portions while keeping an eye on your cat’s body condition. If you feed a mixed diet, remember to include the calories from wet food, dry food and treats.

Is wet cat food better than dry food?

The two formats suit different needs. Wet food contains more moisture and often comes in individual portions that are easy to serve. Dry food is easier to store and can be portioned in advance. A combination of both can work well, as long as the total daily allowance is appropriate and fresh water is always available.

How long can you keep opened wet food?

Put any leftovers in a sealed container in the fridge and follow the manufacturer’s instructions. Many products recommend using them within 24 to 48 hours. Serve the wet food at room temperature, and throw it away if its appearance, smell or packaging seems unusual.
