Adult cat food: how to choose the right diet without waste

Choosing adult cat food is not simply a matter of picking the first familiar brand or recipe that seems to appeal to your pet. Between dry food, wet food, pouches and value packs, some essential information can easily be overlooked.

Attractive packaging can also distort your perception. A recipe advertised as “with chicken” may contain only a small proportion of chicken, while a product presented as a soup may be a complementary food rather than a complete meal. To make an informed purchase, three checks are often enough to avoid disappointment.

Common pitfalls when buying

1. Confusing complete food with complementary food

The wording “complete food” means that the product is designed to meet a cat’s daily nutritional needs when served according to the manufacturer’s recommendations. By contrast, a broth, soup or liquid treat may belong to the category of complementary foods.

For example, Sheba Soup Tuna & Chicken Fillet highlights 16% chicken breast fillet and 4% tuna. However, its product information recommends one pouch per day alongside a complete dry or wet diet. Despite its convenient format, it should therefore not replace your cat’s main meals.

2. Trusting the meat named in the product title rather than the ingredients

“Chicken cat food”, “fish cat food” or “salmon recipe” does not necessarily mean that the highlighted ingredient makes up most of the formula. The best approach is to check the ingredients list and the stated percentages.

Some PURINA ONE recipes, for example, list 17% chicken, turkey or salmon, while several wet-food pouches mention only 4% of the featured ingredient. These products may suit different needs or preferences, but it is better to compare the figures than to rely solely on the packaging images.

3. Buying a large multipack without checking storage

A cat food multipack can reduce the cost per meal, but only if your cat’s consumption rate and storage conditions make sense. Dry food should be kept in a carefully resealed bag or an airtight container. Once opened, pouches can generally be stored in the fridge for between 24 and 48 hours.

A pack of 44 x 85g pouches may be worthwhile for a multi-cat household or for daily wet-food feeding. For a single cat that eats only a little wet food, a smaller pack will help preserve freshness and prevent a build-up of leftovers.

Factors to compare before choosing

Complete food, complementary food or treat

Start by identifying the regulatory category shown on the label:

  • Complete cat food: intended for daily meals, with feeding recommendations.
  • Complementary food: to be combined with a complete food.
  • Treat: to be given occasionally, while taking the overall energy intake into account.

This distinction is particularly important when choosing wet cat food. A complete wet food for adult cats can form the basis of your cat’s diet, while a liquid soup is mainly intended to vary textures or supplement a meal.

Water content and feeding method

Wet foods often have a high water content, generally between 78 and 83% for the products featured. They are sold in pouches or individual cans, with portions that are easy to serve.

Adult cat dry food contains much less moisture and is easier to store after opening. However, you should always leave fresh, clean water available. If you feed a mixed diet, reduce the quantity of each product to avoid exceeding your cat’s daily requirements.

Age, neutering, activity level and sensitivities

A cat aged one year or over will not necessarily have the same needs as a neutered cat, a highly active cat or one that lives exclusively indoors. Look for guidance that matches your cat’s profile:

  • Dry food for neutered cats: check the daily portion and adjust it according to your cat’s weight and body condition.
  • Indoor cat food: dedicated formulas may contain more fibre, such as the PURINA ONE Indoor products, which list 5.5% crude fibre.
  • Food for sensitive cats: examine the protein sources, cereals and additives to identify ingredients your pet may tolerate less well.
  • Fussy cat: an assortment of chicken, fish, beef or turkey recipes can make it easier to rotate flavours.

Any change of diet should be made gradually. Allow around seven days when switching dry food, giving your cat’s digestive system time to adjust while you monitor how well the new food is tolerated.

Frequently asked questions about adult cat food

How much food should you give an adult cat ?

The right portion depends on your cat’s weight, age, activity level, neutering status and type of food. Start by checking the table on the packaging, then make gradual adjustments while monitoring your cat’s body shape and weight. Manufacturers’ recommended quantities are guidelines : they will not automatically suit every cat.

Can you mix dry and wet food for an adult cat ?

Yes, a mixed diet is perfectly possible provided both products are complete foods and the total quantity is appropriate. Wet food provides more water, while dry food is easy to measure and store. Simply avoid adding together the full recommended portions for each product without reducing them.

How long can you keep an opened pouch?

Place any leftovers in the fridge and follow the storage period stated on the packaging, generally between 24 and 48 hours depending on the product. Serve the portion at room temperature. Throw away any swollen or damaged pouch, as well as any food whose smell or appearance has changed.
