Buying Cat Food: How to Choose the Right Food Without Falling for Marketing Traps

Buying cat food seems simple enough – until you have to choose between wet cat food, dry cat food, kitten food, grain-free cat food and special formulas for neutered or senior cats. Packaging often emphasises flavour, appealing ingredients or claims about how the food works. Yet a striking front label doesn't always tell you enough about whether it's suitable for your cat.

Three Common Traps When Buying Cat Food

1. Confusing a catchy flavour name with a high proportion of that ingredient
“With chicken” or “with fish” doesn't automatically mean chicken or fish is the main ingredient. Always check the composition. For example, some products state that the named meat makes up just 4% of the pieces, while the overall composition also contains grains, plant-based protein extracts and animal by-products.

2. Using a supplementary treat as a complete meal
Cat treats, lickable sticks and toppers are not necessarily complete cat food. INABA Churu Cat Tuna, for instance, is labelled as complementary pet food. According to the description, the product contains 91% moisture and is intended as a treat or addition, not as a daily main meal.

3. Buying a large multipack without first checking whether your cat will accept it
A cat food multipack can be good value, but your cat may refuse a particular texture or flavour. When trying a new formula, buy a smaller size first if available. A box of 44 or 60 portions is only practical once you know your cat will eat the food.

The Key Product Details to Check

1. Complete or Complementary Food

Look on the label for complete pet food. This means the product is intended as daily nutrition within the stated guidelines. Wet food in portion pouches, such as Whiskas Adult Wet Cat Food Tasty Mix in Sauce, is described as complete wet food for adult cats.

A complementary product, such as cat treats, should be given alongside a full meal. Keep an eye on the calories and adjust the daily amount of main food accordingly.

2. Age, Life Stage and Special Needs

Choose cat food for the correct life stage:

  • Kitten food has a nutritional profile designed for growth. Whiskas Junior Classic Selection and Iams cat kitten/junior chicken are examples of products offered for kittens.
  • Adult cat food is intended for the adult life stage. Always check the feeding guide and your cat's weight.
  • Senior cat food is aimed at cats from a certain age. Purina One Senior Chicken & Whole Grain Formula is described as being for cats aged 7 years and older.
  • Cat food for neutered cats may have an adjusted energy or fat ratio. Farmina N&D Ocean Neutered Cat Herring, for example, states 11% fat; Purina One Sterilcat states 13% fat and 37% protein according to the analytical data.

A special formula does not replace veterinary advice for illness, persistent symptoms or a prescribed diet.

3. Composition, Moisture and Storage Convenience

Dry cat food stays fresh longer after opening if you seal the bag properly and store it in a dry place. Wet cat food typically contains a lot of moisture and is often supplied in individual portions. Once opened, any leftovers should be kept refrigerated according to the label and usually used within 24 to 48 hours.

Pay attention to these points:

  • Protein, fat, fibre and moisture in the analytical constituents.
  • The order of ingredients on the label.
  • The recommended amount per body weight.
  • Whether grains are present. Grain-free cat food is not automatically necessary or better for every cat.
  • Whether the flavour matches your cat's preference, such as cat food with chicken or cat food with fish.
  • The pack size and price per kilogram or per meal.

Brands may make additional claims about digestion, urinary tract health, coat condition or immunity. Don't treat such claims as established medical facts. View them as product information from the brand and focus primarily on the verifiable composition.

Frequently Asked Questions About Buying Cat Food

Which cat food is suitable for an adult cat?

Choose a product labelled complete food for adult cats. Then consider your cat's weight, activity level and life stage. An indoor cat with little exercise may need a different portion size than an active outdoor cat. It's best to weigh dry food rather than relying on guesswork.

Is wet cat food better than dry cat food?

That depends on your cat's preference, the composition and your daily routine. Wet food typically contains a lot of moisture and is easy to serve in individual portions. Dry food is practical to store and weigh out. A combination can also work, as long as you monitor the total daily amount and follow the feeding guide.

How do I switch to a different cat food?

Gradually mix the new food with the old over at least seven days. Increase the proportion of new food each day if your cat tolerates it well. Stop if you see persistent diarrhoea, vomiting or refusal to eat, and contact a vet if you're unsure. Always provide fresh drinking water and store opened food according to the instructions on the packaging.
