Choosing fish-based cat food: a practical guide for every life stage

Fish-based cat food is popular for its aroma, flavour and wide range of recipes. However, an image of salmon or tuna on the packaging does not automatically mean that fish is the main ingredient. Some recipes contain only a small percentage of the fish named, while other ingredients appear further up the composition.

So pay particular attention to the label rather than marketing terms. With these points in mind, you can make a more informed choice between wet cat food, dry cat food, kitten food and food for adult or neutered cats.

Common pitfalls when choosing fish-based cat food

1. A fish name on the front does not tell you everything

“ with salmon” or “with tuna” does not necessarily mean that the product consists mainly of salmon or tuna. Some varieties, for example, list just 4% of the named fish species. The rest may consist of meat and animal derivatives, cereals, vegetable protein extracts or other fish derivatives.

That is why you should check the full composition. Ingredients are generally listed in descending order by quantity. Also look for a specific statement such as “4% tuna” or “26% dried cod”.

2. Confusing complete and complementary food

Complete cat food is intended as a daily diet when this is clearly stated on the label. Complementary food, such as some soups, snacks or meal toppers, does not independently provide all the nutrients required.

According to the product information, Felix Soup Fish Wet Cat Food is complementary food for adult cats. The recommended amount is one pouch per 4 kg of body weight per day, as an addition to a complete meal. Its high moisture content can be useful for adding variety, but it does not replace a complete diet.

3. Ignoring age and activity levels

A kitten has different energy and nutritional needs from a calm adult cat. After neutering, it may also be sensible to review energy intake and portion size. A bag of fish-based cat food for adult cats is therefore not automatically suitable for a kitten.

Look for descriptions such as kitten, adult, neutered or “neutered cats”. If you have questions about a medical condition, allergy or special diet, discuss your choice with a vet. Product claims about digestion, coat or weight management are not a substitute for professional nutritional advice.

Three specifications to check before buying

1. Life stage and nutritional status

First check which life stage the product is intended for:

  • Fish-based kitten food: formulated for growth; according to the product description, Farmina N&D Ocean Kitten Cod is sold as complete food for kittens and pregnant or nursing cats.
  • Cat food for adult cats: suitable for cats from adulthood onwards, depending on the label.
  • Cat food for neutered cats: as well as looking for the term “neutered”, check the energy, fat and feeding guidance.
  • Complementary food: use it alongside complete food, not instead of it.

The feeding guideline on the packaging is a starting point. Adjust the portion according to your cat’s weight, activity level and body condition.

2. Moisture content and texture

Wet food contains considerably more moisture than dry food. This makes wet cat food appealing to owners who want to offer extra variety or whose cat drinks very little. It is not a medical treatment, but it can be a practical part of your cat’s daily fluid intake.

Choose the texture according to your cat’s preference and eating habits:

  • Pâté or mousse: smooth and soft, such as g’woon Cat Paté Salmon or g’woon Cat Mousse with Tuna.
  • Chunks in jelly or gravy: suitable for cats that prefer more texture.
  • Soup: mainly intended as a complementary food.
  • Dry food: easy to portion and store at room temperature, but always make sure fresh water is available.

3. Fish percentage, protein and cereals

The term grain-free cat food is not an automatic guarantee of quality. Look at the complete recipe and the analytical constituents. According to the product specifications, Farmina N&D Ocean Cat Herring with Orange lists 44% crude protein, 20% fat and 8% moisture, among other values. According to the product information provided, the composition contains no rice, maize, soya, peas or lentils.

Another option is Farmina N&D Ocean Cod, Spelt, Oats and Orange Flavor Adult Cat Food. According to the label, this recipe contains 27% fresh cod, 26% dehydrated cod, spelt and oats. It is therefore not a grain-free formula. That does not necessarily present a problem if your cat tolerates cereals well; it mainly shows why you should read the ingredients list.

Helpful buying tips for everyday use

  • Choose a multipack of cat food if your cat enjoys switching between tuna, salmon, cod or sea fish.
  • For small pouches and trays, check the price per kilo rather than just the price per pack.
  • Store dry food sealed in a cool, dry place.
  • Cover opened wet food, keep it refrigerated and follow the storage period shown on the packaging.
  • Switch gradually to a new food to help limit digestive problems caused by a sudden change.
  • Always provide fresh drinking water with dry food. Only combine wet and dry food with adjusted portions.

Frequently asked questions about fish-based cat food

Is cat food with salmon or tuna suitable for every cat?

Not automatically. Check the life stage, nutritional status and composition. Cats with a known food sensitivity may react differently to fish or other protein sources. If symptoms persist, ask a vet for advice.

Is wet cat food better than dry food?

Both types can form part of a daily feeding plan when they are labelled as complete food. Wet food contains more moisture, while dry food is practical to store and portion. The choice depends on your cat’s preference, portion control and the information on the label.

How long can opened cat food be kept?

Always follow the instructions on the packaging. The product information provided states that several wet food products can be kept refrigerated for up to 48 hours. Discard leftovers if the food smells unusual, changes colour or has been left out of the fridge for too long.
