Cat food: how to choose the right diet without falling into common traps

Choosing cat food is not simply a matter of being won over by an appetising photo or a promise highlighted on the packaging. From dry cat food and wet cat food to pouches, mousse and liquid cat treats, differences in ingredients, texture and nutritional value can affect both your budget and your pet’s eating habits.

Before you reach the checkout, three common traps are worth watching out for:

  • Confusing complete and complementary food: a liquid treat or snack cannot replace main meals.
  • Relying solely on the recipe name: wording such as “with chicken” or “with fish” should be checked against the actual percentage listed in the ingredients.
  • Buying a large pack without considering your cat’s profile: a bag of dry food for sterilised cats or a large multipack of cat food can be cost-effective, but only if the recipe and pack size genuinely match your cat’s needs.

What to check on the label

1. Nutritional status and your cat’s age

The wording “complete food” indicates that the product is designed to meet your cat’s daily nutritional needs when used as intended. By contrast, complementary food must be given alongside a main diet.

Age is just as important. Kitten food should be suitable for growth, generally from weaning until 12 months, according to the manufacturer’s guidance. For an adult cat, look for a formula specifically intended as adult cat food. Sterilised cats may also benefit from a recipe with calorie allowances and serving quantities suited to their lifestyle. This does not remove the need to monitor their weight regularly.

2. Daily allowance and product density

Compare the recommended serving for your cat’s weight rather than looking only at the price of the pack. Wet cat food contains a great deal of water, so the stated protein and fat levels should be considered alongside the moisture content.

For example, Sheba Délices du Jour aux Poissons contains 82% moisture, with 50g portions. The manufacturer recommends around 4 to 5 pouches per day for a 3kg cat, adjusted according to its activity level and metabolism. These guidelines are a starting point, not a rule that applies to every cat.

For dry food, a small kitchen scale makes it easy to weigh out each serving accurately. The 7kg pack of WHISKAS Adult Sterilized recommends between 30 and 75g per day depending on the cat’s weight, as well as a gradual transition over 7 to 10 days.

3. Ingredients and claims that need context

Check the order of the ingredients, the stated percentages and the analytical constituents. A recipe may combine several sources of animal protein, cereals, vegetable protein extracts or animal by-products. It is better to read the full ingredients list than to focus only on the ingredient highlighted on the front of the pack.

Claims such as “no artificial colourings” or “no added sugars” describe a feature of the recipe, but they are not enough to determine whether it is suitable for your cat. If your cat has a food sensitivity, is overweight or has a health condition, ask your vet for advice before changing its diet.

Which texture should you choose based on your cat’s habits?

  • Dry cat food: easy to measure and store, it requires fresh water to be available at all times. Seal the bag carefully after each use.
  • Wet cat food and cat food pouches: individual portions reduce leftovers and make it easier to control the amount served.
  • Cat mousse: its smooth texture may appeal to cats that prefer silky preparations, but every animal has its own preferences.
  • Mixed feeding: this combines dry food with wet cat food. You should reduce the quantities of each product to maintain a balanced daily allowance.
  • Liquid cat treats: these remain complementary foods. They can be used as a reward or mixed with dry food, but must not replace a complete food.

Practical advice before and after buying

  • Compare the price per kilogram, especially between a multipack of pouches and a large bag of dry food.
  • Check that the packaging is intact and that the best-before date is clearly legible.
  • Introduce any new food gradually over several days.
  • Store dry food in a dry place, in an airtight container.
  • Place opened wet food in the fridge and follow the stated storage period, generally 24 to 48 hours.
  • Always leave a bowl of clean, fresh water available.
  • For a sterilised cat, monitor its weight regularly and adjust the serving sizes rather than keeping the bowl topped up at all times.

Frequently asked questions about cat food

How much food should you give an adult cat?

The amount depends on the cat’s weight, activity level, age, whether it has been sterilised and the type of food. Start by following the serving guide on the packaging, then adjust it according to changes in your cat’s body shape and your vet’s recommendations. With mixed feeding, add together the calorie contributions of both formats instead of applying two complete daily allowances.

Can wet cat food replace dry food?

Yes, provided the wet food is described as a complete food for the relevant age category. Pouches and tins provide more moisture, while dry food is easier to store and measure. However, the wording “complementary food” means that the product is not suitable for replacing daily meals.

How long can cat food be kept after opening?

Follow the instructions on the label. Wet food should generally be covered, placed in the fridge and consumed within 24 to 48 hours. Dry food keeps for longer once the bag has been properly resealed, but its freshness gradually declines, so choose a pack size that matches your household’s actual consumption.
