Choosing cat food without falling into marketing traps: how to find dry food that suits your cat

A bag of cat food featuring words such as “natural”, “premium” or “grain-free” can quickly seem like a safe choice. Yet these terms do not always tell you enough about whether the food is suitable for your cat. An eight-year-old indoor cat has different nutritional needs from a growing kitten. Age, activity levels, neutering and digestion also play a part.

As a Joybuy Product Recommendation Officer, I focus mainly on verifiable information: the target group stated on the label, the ingredients, the analytical constituents, the pack size and the feeding instructions. This helps you avoid paying mainly for marketing language.

Three common pitfalls when choosing cat food

1. One prominent ingredient does not tell the whole story

Does the packaging say “cat food with chicken” or “cat food with fish”? If so, check the percentage. According to the product information, Felix Double the Tasty Beef and Chicken contains 2% beef and 2% chicken in the relevant kibbles. So you should not interpret the claim “with beef and chicken” as meaning “mainly beef and chicken”.

Always check the full ingredients list. Ingredients are generally listed in descending order by weight. Also pay attention to the difference between fresh meat, dried animal proteins, grains, vegetable protein extracts and fats.

2. “Grain-free” is not an automatic guarantee of quality

Grain-free cat food may suit owners who want to avoid grains, but on its own it does not mean that the food will be easier for every cat to digest. Grain-free recipes often contain other carbohydrate sources, such as peas, chickpeas, potato or quinoa.

For a cat with a sensitive stomach, the overall composition matters more than one term on the front of the pack. Change food gradually as well. Switching over approximately seven days can help limit sudden digestive problems caused by an abrupt change.

3. A large bag is not always better value

A 5 or 10 kg pack often has a lower price per kilogram, but dry cat food loses its aroma more quickly after opening. Store the bag in a cool, dry place and keep it tightly sealed. Only buy in bulk if your cat already accepts the food well and there is plenty of time left before the best-before date.

Do not compare only the price of the bag. Also consider the recommended daily amount, your cat’s weight and the amount of food that may go to waste.

What to look out for before you buy

Age and life stage

For kitten food, it should be clearly stated that the product is suitable from weaning to, for example, 12 months. Kittens have different nutritional needs from adult cats. According to the product description, Purina One Junior is intended for kittens from weaning to 12 months, as well as pregnant or nursing cats.

Cat food for adult cats is generally formulated for cats from around one year old. There are also varieties such as senior cat food for cats aged seven and over. Always check the age guidance on the packaging, and adjust the portion according to your cat’s growth, activity levels and body condition.

Specific lifestyles

Indoor cats often get less exercise than cats that go outside. An indoor formula may therefore contain a different balance of protein and fat. According to the product information, the Purina One Bifensis Indoor Adult variety contains turkey, whole grains, chicory and fibre. According to Purina’s own research, these fibres may help move hair through the digestive system and out in the faeces; this is a brand claim and is not a guarantee for every cat.

With cat food for neutered cats, portion control and energy intake are particularly important. Purina One Sterilcat states that it has an adjusted protein-to-fat ratio and balanced minerals. This makes it suitable for comparison with other recipes, but it does not replace an individual assessment of your cat’s weight or urinary tract issues.

“Complete and balanced”

For a main diet, choose a product labelled as complete and balanced cat food or as complete food. This indicates that the product is intended to be fed as a daily diet, according to the feeding instructions.

Also check:

  • the analytical constituents, such as crude protein, fat, fibre and ash;
  • the added vitamins, minerals and taurine;
  • the recommended amount for your cat’s body weight;
  • whether it is labelled “for adult cats”, “for kittens” or for another target group;
  • access to fresh drinking water, particularly when feeding dry food.

A “sensitive stomach” is not a diagnosis. If your cat has persistent vomiting, diarrhoea, weight loss or a noticeable change in eating habits, consulting a vet is wiser than repeatedly changing its food.

Practical tips for changing food and storage

  • Mix the new food gradually with the old food over approximately seven days.
  • Weigh out the daily portion instead of topping up the bowl without restriction.
  • Keep an eye on your cat’s weight and body condition.
  • Always provide fresh drinking water with dry cat food.
  • Seal the packaging securely after each use and store it in a dry place away from direct sunlight.
  • Check the best-before date and batch information on the packaging.

Frequently asked questions about cat food

Which cat food is suitable for a kitten?

Choose kitten food that clearly states it is suitable from weaning to 12 months. Food for adult cats does not automatically contain the nutritional ratios needed for growth. Follow the portion guidance on the bag and, if necessary, divide the food into several meals.

How long can you keep an opened bag of dry cat food?

This varies by brand and packaging. Keep dry food tightly sealed in a cool, dry place. The exact information on how long it remains suitable after opening can be found on the label. If the food smells unusual, has become damp or your cat suddenly refuses it, check its quality before feeding it.

Is expensive cat food cheaper to use?

Not always. Compare the price per kilogram with the recommended daily amount. Food with a higher price per bag may last longer because the portion is smaller, while a large pack may seem good value but be less practical if your cat does not like the food. So look at the price per day, not just the checkout price.
