Choosing cat food without costly mistakes: a practical guide for every life stage

Buying cat food seems simple until you are faced with a shelf or online range containing dozens of options. Dry food, wet food, kitten food, food for sterilised cats and cat treats all serve different purposes. An appealing package does not always tell you whether the food is suitable for your cat.

The following pitfalls are common:

  • Confusing a flavour name with the main ingredient. “Cat food with chicken”, for example, may also contain other animal ingredients. Always check the full composition and the percentage stated.
  • Treating a snack as complete cat food. Liquid treats and soups are often complementary food. They should not simply replace a complete meal.
  • Looking only at the price per kilogram. A large bag of dry food may seem good value, but the correct daily portion depends on weight, age, activity level and the nutritional value shown on the label.
  • Choosing a special variety without checking the life stage. Kitten food is designed for growth, while adult cat food has a different nutritional composition. An adapted variety may be practical for a sterilised cat, but portion control remains important.

Which specifications should you check?

1. Complete or complementary food

Look for “complete pet food” on the packaging when you are looking for a daily main meal. This means that, according to the product information, the product is intended to be given as complete nutrition. If it says “complementary pet food”, as is the case with many cat treats, soups and toppers, use it as an extra alongside a complete meal.

When in doubt, follow the feeding guidelines on the packaging. A treat may contain few calories, but several small portions a day still count towards your cat’s intake.

2. Age and specific circumstances

Kitten food is tailored to the growth stage. According to the product description, Purina One Junior is intended from weaning to 12 months and contains, among other things, DHA, protein and minerals. The product is also described as suitable for pregnant or nursing cats. Always check that the age range on your packaging matches your cat’s age.

For adult cats, varieties are available from around one year of age. For a sterilised or neutered cat, a product with adapted nutritional values may suit its changed energy requirements. For example, Purina One Sterilcat states that it has an adapted protein-to-fat ratio and balanced minerals. These are product specifications; they do not guarantee a particular result for every cat.

3. Texture, moisture and convenient storage

Dry cat food is easy to portion and simple to store in a sealed container. Pay attention to the bag size and use an airtight storage container once the packaging has been opened.

Wet cat food generally contains a high level of moisture and is available as pâté, chunks in gravy, mousse and soup. Check the net weight per pouch or tin, as well as the storage instructions after opening. A small tin or pouch is practical for one meal, while multipacks can be useful for households with several cats.

If your cat has a sensitive stomach, it is sensible to introduce any change gradually. Check the ingredients for possible triggers. The term “sensitive” is a product positioning statement, not a medical diagnosis. If symptoms persist or your cat has been prescribed a diet, consult a vet.

How to use cat food in practice

Make the change gradually by mixing the new food with the old food. Increase the proportion of the new product step by step and monitor your cat’s appetite, stools and body condition. Use the feeding guide as a starting point, not a fixed rule: an active cat may need a different amount from a quiet indoor cat.

Store dry food in a cool, dry place in a tightly sealed container. Serve wet food at room temperature and refrigerate leftovers as instructed on the label. Give cat treats in moderation and reduce the main meal if necessary. For example, Felix Deli Moments Salmon is complementary food for adult and senior cats; the product information recommends one 10-gram pouch per day as a treat. INABA CHURU Cat Chicken likewise states that it is a snack or supplement, not a replacement for complete cat food.

Frequently asked questions about cat food

What is the difference between wet and dry cat food?

Dry food contains little moisture and is easy to store and portion. Wet food has a soft texture and a higher moisture content. The choice depends on your cat’s preference, your practical circumstances and the feeding guidelines. With both types, check whether the food is complete or complementary.

How long does cat food keep after opening?

Dry food generally stays usable for longer when stored in an airtight container in a cool, dry place. Opened wet food should be refrigerated according to the packaging and used within the stated time period. Throw away leftovers if the smell, colour or texture seems unusual.

How much does cat food cost per month?

This depends on your cat’s weight, daily portion, type of food and the amount of treats given. Calculate the cost by dividing the price per pack by the number of daily portions. A combination of dry and wet food can be practical, but always compare the recommended quantity and the cost per day rather than just the purchase price.
