Choosing cat food with fish: look out for these ingredients, pack sizes and food labels

Cat food with fish may seem straightforward to choose at first glance. However, an appealing flavour description such as “salmon” or “tuna” may not tell the whole story. Is fish listed as the first ingredient? Is the product complete cat food or just a complementary option? And does the pack size suit the amount your cat eats each day?

With these checks, you can compare cat food with fish, wet food, dry food and complementary treats without relying solely on marketing claims.

Common pitfalls when choosing cat food with fish

1. A fish flavour does not automatically mean there is a lot of fish

The front of the pack may prominently feature “salmon”, “tuna” or “sea fish”, while the proportion of fish in the full recipe is limited. So always check the ingredients list. For example, Felix Double the Tasty Salmon, Sea Fish & Beetroot states that the total product contains 1.7% salmon and 1.7% sea fish. That is different from a recipe in which fish is the main ingredient.

According to the product label, Farmina N&D Ocean Cod contains 27% fresh cod and 26% dehydrated cod, among other ingredients. Percentages like these give you a clearer picture than the variety name alone.

2. A treat or cat soup does not replace a complete meal

Products such as INABA Churu Cat Tuna and INABA Bisque Cat Tuna Recipe are described as complementary food in the product information. They can be served as a treat, topping or moist addition, but are not intended to provide a complete daily meal.

Cat soup often has a high moisture content and can be useful for cats that do not drink much. According to the label, INABA Broth Chicken with Salmon Recipe contains 93% moisture. This makes it a moist treat, not automatically a complete cat food.

3. A larger pack is not always better value

Dry food remains practical to store for longer after opening than wet food, but it must be sealed properly and kept in a cool, dry place. With wet food, smaller portions are often useful for reducing leftovers. A cat food multipack may appear to offer good value, but check the following first:

  • the total quantity per pack;
  • the best-before date;
  • the recommended daily portion;
  • whether all the flavours are suitable for your cat;
  • the storage period after opening.

If your cat refuses one of the varieties, a large multipack ultimately becomes less practical.

Important specifications to check

Complete cat food or complementary food?

Look for the wording “complete food” or “complete pet food” on the label. This means that, according to the product information, the product is intended to be given as daily food within the stated portions.

The following products, among others, are labelled as complete food for adult cats from around one year old:

  • Purina One Adult Salmon;
  • Felix Double the Tasty Salmon, Sea Fish & Beetroot;
  • Gourmet Gold varieties;
  • g’woon Adult Pâté with Salmon;
  • Felix Seaside Sensations dry food.

With complementary products such as fish cat treats, cat soup and INABA Churu, the main meal should remain a complete food.

Moisture content: do not compare wet and dry food directly

Wet cat food generally contains much more moisture than dry food. According to the label, INABA Churu Cat Tuna has a moisture content of 91%, while INABA Bisque Cat Tuna contains 86%. Felix Soup Fish is also described as a product with a high moisture content.

However, a high moisture percentage does not tell you how much protein or energy your cat consumes each day. You should also check:

  • crude protein;
  • crude fat;
  • crude ash;
  • the recommended daily portion;
  • the energy information, if provided.

With dry food, nutrients are often more concentrated because it contains less moisture. Measure out the portion according to the packaging and always provide fresh drinking water.

Age and intended use

Cat food for adult cats is not automatically suitable for kittens. A product such as g’woon Chunks in Jelly Fish and Meat Variation Junior is specifically intended for young cats. For an adult cat, check that the packaging clearly states “adult” or “from 1 year”.

You should also choose according to how the food will be used:

  • Dry cat food: practical for set meal portions and easy to store.
  • Wet food: suitable if your cat prefers a soft texture or extra moisture in its meal.
  • Fish cat treats: for variety, rewards or use as a topping.
  • Cat soup: a complementary moist treat, not a replacement for complete food.
  • Cat food multipack: useful for variety and portion-controlled packs, provided your cat accepts the flavours.

Frequently asked questions about cat food with fish

Is cat food with salmon suitable for every adult cat?

Not every cat reacts to fish in the same way. Check the full ingredients list for other animal protein sources, grains or ingredients your cat has previously reacted badly to. If in doubt, start with a small pack and change the food gradually.

Is wet cat food better than dry food?

That depends on your cat’s preferences and daily routine. Wet food generally contains more moisture, while dry food is easy to portion and store. Both can be suitable, provided the product is appropriate for your cat’s age and clearly labelled as complete food. Combining the two can be practical, but adjust the portions to prevent overfeeding.

How often can I give my cat tuna cat food or a fish treat?

Follow the feeding instructions on the packaging. For example, INABA Churu Cat Tuna recommends one to two sticks per day for adult cats as a treat or complementary food. Do not give complementary products without limits, and take the main meal into account. Fresh drinking water should always be available.
