Choosing cat food with fish: how to compare flavour, ingredients and use

Cat food with fish is popular with Dutch cat owners, especially when a cat is fussy or enjoys wet food with tuna and salmon. However, a picture of a fish on the packaging does not tell you everything about the ingredients. The fish species may make up only a small percentage of the recipe, even though the product is marketed as a tuna or salmon variety.

The difference between complete food and complementary food is also regularly overlooked. This can lead to the wrong purchase or an unbalanced daily diet. Use the following checks to compare cat food with fish more effectively.

Three common pitfalls when choosing cat food with fish

1. The fish name does not tell you how much fish it contains

With cat food containing tuna, salmon or cod, the fish species is often clearly shown on the front. Always check the ingredients list and the percentage. For example, several wet food recipes in this selection state that they contain 4% tuna, salmon or other fish. The remainder may consist of meat and animal derivatives, cereals, vegetable protein extracts and minerals.

A product with a fish name is therefore not automatically food in which fish is the main ingredient.

2. A snack or soup cannot replace a main meal

According to the product information, INABA Churu and INABA Bisque are complementary foods. They can be given as a fish-based cat treat, topping or extra, but are not intended to replace a complete daily meal. Felix Soup and some hydration products also have a complementary function.

For the main meal, look for the legal designation complete food for adult cats. Give complementary food in moderation and adjust the amount of main food if necessary.

3. Grain-free does not automatically mean more suitable

Grain-free cat food may suit a specific dietary choice, but “grain-free” on its own says nothing about whether it is suitable for your cat overall. Also consider life stage, energy content, protein and fat levels, and the recommended portion. If your cat has a food allergy or persistent gastrointestinal problems, consulting a vet is wiser than trying several diets yourself.

Important points to check

Complete food or complementary food?

For cat food intended for adult cats, the wording on the packaging is the first thing to check. Complete food is intended to be given as a daily meal, within the recommended quantities. Wet cat food generally contains a lot of moisture and can be useful if your cat drinks very little, but nutritional values vary from one recipe to another.

Complementary products are useful for variety or as a reward. For example, give INABA Bisque as a soup-like treat or mixed through dry cat food, not as a replacement for a complete meal.

Moisture content and texture

Wet food has a higher moisture content than dry food. The supplied product information, for example, states 86% moisture for INABA Bisque and 91% moisture for INABA Churu Cat Tuna. This makes these products soft and easy to lick, but they are complementary snacks.

Also consider the texture:

  • Mousse is soft and suitable for cats that prefer smooth textures.
  • Pieces in jelly or gravy offer more variety for chewing and licking.
  • Soup or bisque is mainly suitable as a supplement or topping.
  • Kibble is practical to portion and easy to store, but contains considerably less moisture than wet food.

Life stage, weight and portions

A product for adult cats is not automatically suitable for every adult cat. Neutered cats may sometimes benefit from food with adjusted energy and fat levels. According to the product description, Farmina N&D Ocean Neutered Cat Herring contains 11% fat and is intended as complete food for neutered or spayed adult cats.

Always follow the feeding guidelines on the packaging and adjust the amount according to weight, activity level and body condition. When switching to new dry or wet food, make the change gradually, preferably over a period of at least seven days.

Wet food, dry food or snacks?

Choose wet cat food when moisture and a soft texture are important. A multipack, such as Felix Fish Mix or Gourmet Gold Mousse Tuna 24 x 85 g, keeps portions easy to manage and reduces opened leftovers in the fridge.

Dry cat food is more convenient for longer-term storage and automatic feeders. Store an opened bag sealed, somewhere cool and dry. Only combine dry and wet food after recalculating the total daily amount.

For extra variety, fish-based cat treats are suitable. According to the product information, INABA Churu Cat Tuna contains 91% moisture and approximately 6 calories per stick. This makes it a small reward, not a complete food. For an alternative range, also see ordinary tuna cat food.

Frequently asked questions about cat food with fish

Is cat food with tuna suitable as a daily food?

That depends on the wording on the packaging. A product labelled as complete food for adult cats can be used as a main meal according to the feeding guidelines. Tuna soup, bisque and Churu are complementary products and must not replace the main food.

Is grain-free cat food necessary for every cat?

No. Grain-free is a specific recipe choice, not a general requirement. Compare the complete ingredients list, nutritional values and target group. If an allergy is suspected, professional dietary advice is preferable.

How should I store opened cat food with fish?

Cover opened wet food and store it in the fridge. Use it according to the instructions on the packaging; some products must be used within 24 hours, while others can be kept for up to two days. Do not leave wet food at room temperature for extended periods, and always provide fresh drinking water.
