Adult cat food: how to choose the right diet without paying for marketing

Choosing adult cat food is not simply a matter of comparing flavours or hunting for a special offer. From dry food and wet food to pouches and liquid cat treats, packaging often highlights appetising ingredients without always making their actual proportion clear or explaining where the product fits into your cat’s daily diet.

Three pitfalls come up time and again:

  • Confusing complete and complementary food: a soup, lickable treat or fillets in sauce can add variety to a meal, but may not replace a complete cat food.
  • Relying on the recipe name: salmon or tuna cat food may contain only a limited amount of fish. The ingredients list and stated percentages tell you far more than the picture printed on the packet.
  • Choosing a large format without considering how it will be used: a bag weighing several kilos may be worthwhile in a multi-cat household, but become inconvenient if your pet quickly tires of the same food or you do not have enough storage space.

Criteria to check before buying

1. Complete or complementary food

The wording ‘complete food’ means that the product can make up a cat’s daily ration when served according to the manufacturer’s recommendations. By contrast, complementary food is intended to be given alongside a complete staple diet.

This is the case with some liquid cat treats. The INABA Churu Cat Tuna product, for example, contains 91 % moisture and only 6 calories per serving. However, it is presented as a reward, accompaniment or topping to add to dry or wet food.

Before adding a product to your basket, check the following information:

  • the target age, such as adult cats aged 1 to 7 years or cats over one year old ;
  • whether it is labelled ‘complete food’ or ‘complementary food’ ;
  • the daily feeding table ;
  • any specific recommendations for a neutered, less active or indoor-only cat.

2. Ingredients and analytical constituents

Ingredients are generally listed in descending order by weight. However, this list alone is not enough to compare two recipes. Also look at the analytical constituents: protein, fat, cellulose, ash and moisture.

As a useful reference, Purina One Bifensis salmon dry food contains 34 % protein, 14 % fat and 8 % moisture. Like all dry food, it provides relatively little water, so a bowl of clean drinking water should always be available.

Water content is considerably higher in wet cat food. PURINA’s salmon and turkey recipe contains 78 % moisture, compared with 84 % for Sheba Chicken & Tuna fillets. These figures describe the product’s composition; they are not a medical guarantee or a promise of effectiveness.

3. Format, storage and changing foods

85 g cat food pouches are easy to portion and help minimise leftovers. Once opened, they should be kept in the fridge and used within the period stated on the packaging, generally within 24 to 48 hours depending on the product.

For the 60 g Sheba trays, the recommendations call for refrigeration and consumption within two days of opening. Sheba soups in 40 g pouches, on the other hand, should be consumed within 24 hours.

If you change your adult cat’s dry food, allow around seven days for a gradual transition when recommended by the manufacturer. Gradually mix the new recipe with the old one so that you can monitor your cat’s tolerance and any changes in appetite.

Frequently asked questions about adult cat food

How much food should you give an adult cat ?

The right amount depends on your cat’s weight, age, activity level, neutering status and the product’s energy density. Use the feeding table on the packaging as a starting point, then adjust the quantity according to changes in your cat’s body condition. Treats should also be included in the total daily ration.

Can you mix dry and wet cat food ?

Yes, this is very common. Simply reduce the quantity of each type of food to avoid overfeeding. The manufacturer’s recommendations can help you convert a portion of wet food into the equivalent amount of dry food. Even if your cat eats pouches or soup, always leave a bowl of fresh water available.

How long can an opened product be kept ?

Always check the label first. In general, opened wet food should be refrigerated in an airtight container and consumed promptly. Soup or a liquid treat may have an even shorter shelf life once opened. Dry food should be kept in a properly resealed bag, away from moisture and heat.
