Cat food: how to choose the right diet without wasting money

Choosing cat food is not simply a matter of comparing flavours and special offers. Between “natural” claims, large pack sizes and recipes tailored to every type of cat, some essential information can easily be overlooked. Misinterpreting the ingredients, serving a complementary food as the main meal or offering portions that are too generous can quickly push up the cost.

This guide will help you compare dry cat food, wet cat food, recipes for kittens and sterilised cats, as well as the value pack sizes available online.

Common pitfalls when buying cat food

1. Confusing complete food with treats

The term “complete food” means that the product is designed to meet a cat’s nutritional needs when served according to the recommendations on the packaging. By contrast, soups, pastes and liquid cat treats are generally complementary foods.

For example, a tuna and chicken soup in pouches can provide moisture and add some variety to your cat’s usual meal. However, it should not replace the main diet. Always check the product’s legal designation before adding it to your basket.

2. Relying solely on the flavour name

“Chicken” or “salmon” does not necessarily mean that the ingredient makes up the majority of the recipe. When an ingredient is highlighted, its proportion must be stated in the ingredients list. Among the products featured below, some recipes contain 4% chicken, while a Vitakraft salmon mousse contains 6.8% salmon.

The product name is mainly designed to catch your eye. To compare chicken dry cat food, salmon dry cat food or wet food in gravy objectively, you therefore need to check the ingredients list.

3. Buying a large pack without checking storage requirements

A 7 or 7.5 kg bag can reduce the price per kilo, but only if you can store it properly. Once opened, keep dry food in a dry place and seal the bag carefully after each use. Opened pouches and tins should generally be kept in the fridge and consumed within 24 to 48 hours, depending on the manufacturer’s instructions.

A cat food multipack or meal bundle can be convenient, provided you choose an assortment your cat genuinely enjoys.

What to check before ordering

Age and physiological profile

Your first choice should match your cat’s life stage:

  • Kitten food: a recipe designed for growth, with portions suited to the kitten’s age and weight.
  • Adult cat food: a formula intended for an animal that has finished growing.
  • Food for sterilised cats: portions and energy density should be monitored, particularly if your cat tends to gain weight.
  • Sensitive cat: introduce any change gradually and monitor how well your cat tolerates it over the following days.

Kitten food should not automatically be replaced with an adult recipe. Likewise, a formula for sterilised cats is not intended for kittens unless the manufacturer explicitly states otherwise.

The “complete” or “complementary” designation

For everyday meals, look for a clear statement that the food is complete and balanced or is complete food for cats. Wet cat food can perfectly well make up the main meal if it carries this designation. Treats, soups and snacks should remain occasional extras.

The water content is also worth checking. The wet foods in this selection generally contain between 78% and 85% moisture, compared with around 10% for some dry foods. The serving weight is therefore very different, and the percentages cannot be compared directly without taking moisture content into account.

Portion size, net weight and the true cost

To estimate the actual cost, compare the price per meal rather than the price of the pack. A box of 12 85 g portions, a bundle of 18 50 g pouches and a multi-kilo bag of dry food will not last for the same length of time.

To avoid overfeeding:

  1. Weigh dry food portions using a small set of scales.
  2. Adjust the portion according to your cat’s weight, activity level and body condition.
  3. Slightly reduce the main portion when you give your cat a treat.
  4. Introduce any dietary change gradually, generally over 7 to 10 days, in line with the product’s recommendations.

If your cat is overweight, has a known health condition or is undergoing a significant dietary change, seek advice from a vet.

Cat food FAQ

How much food should you give an adult cat?

The amount depends on your cat’s weight, activity level, age, whether it has been sterilised and the type of food. Start by following the feeding guide on the packaging, then regularly monitor your pet’s body shape and weight. Dry food is more energy-dense than wet food, so the quantities in grams are not interchangeable.

Can you mix dry food and wet cat food?

Yes, provided that both products are suitable for your cat’s profile and the total portion remains appropriate. If you add complete wet food, reduce the amount of dry food accordingly. Soup or a liquid treat remains a supplement and cannot replace a complete meal.

How long can you keep opened wet food?

Place any remaining portion in the fridge and follow the instructions on the label. Many manufacturers recommend consuming it within 24 to 48 hours. Serve the wet food at room temperature and throw it away if the packaging is swollen or damaged, or if its smell or appearance has changed.
