Cat food with fish may seem straightforward to choose at first glance. However, packaging can be misleading. An image of salmon or tuna does not automatically mean that fish is the main ingredient. Terms such as “natural”, “grain-free” and “with omega-3” only tell you something when you check the full ingredients list and nutritional status.
For cat owners in the Netherlands, these are three common pitfalls:
Look for “complete cat food” or “complete nutrition” on the packaging. This means that, according to the product information, the product is intended as a daily main food for the stated life stage. If it says “complementary pet food”, “snack” or “treat”, use it as an extra rather than as a replacement for the main meal.
INABA Churu Cat Tuna is a good example. According to the product information, this treat contains 91% moisture and is a complementary product. Felix Deli Moments Salmon and Felix Soup Fish are also intended as snacks or supplements. When using products like these, take the main meal into account and adjust the total amount of food accordingly.
Ingredients are generally listed in descending order by quantity. Therefore, pay attention to:
With wet food containing fish, the percentage of fish is not always the same as the percentage of animal ingredients. Some Felix and Whiskas varieties, for example, state 4% of the named fish species, such as tuna, salmon or cod. This is a verifiable specification, but it does not indicate that the entire recipe consists of that fish.
Fish-based dry food usually has a low moisture content. This means that a portion contains more nutrients per gram, but your cat needs to drink enough. Wet food generally contains much more moisture. Sheba Filets, for example, states 84% moisture, while Whiskas Senior Fish Selection contains 84.5%.
A kitten needs a recipe that is specifically labelled as kitten food. According to the product description, Iams Cat Kitten Ocean Fish contains DHA, taurine, vitamins and minerals, among other nutrients, and is intended for kittens. Farmina N&D Ocean Kitten Cod is also listed as a complete food for kittens.
There are many options for adult cats, such as Iams Naturally Adult Salmon & Rice, Purina One Adult Salmon and Perfect Fit Adult Salmon. A senior cat benefits from a product showing the correct age category, such as Whiskas Senior Wet Cat Food Fish Selection 7+.
For neutered cats, Farmina N&D Ocean Neutered Cat Herring is specifically described as complete food for adult, neutered cats. The product information states 11% fat and 46% crude protein. These are product specifications; the correct portion still depends on your cat’s weight, activity level and body condition.
Fish-based dry food for cats is convenient to store and easy to weigh out. It is suitable for households that want a larger bag, such as Iams Cat Adult Tuna 3 kg or g’woon Adult Cat Bites with Fish 2 kg. Always check the recommended amount and seal the bag securely.
Fish-based wet food for cats contains more moisture and is available in pouches, trays and tins. Felix Delicious Fish Strips in Sauce includes varieties with salmon, tuna, cod and plaice. The product information states 78% moisture and a pack containing 12 pouches of 80 grams. This can be useful if you want to alternate between different fish flavours.
Fish-based cat treats are suitable for bonding time or as a small reward. They should not replace your cat’s daily complete food. For INABA Churu Cat Tuna, the guideline for adult cats is 1 to 2 sticks per day. Include treats in your cat’s overall calorie and nutrition plan.
A gradual switch helps prevent unnecessary acceptance issues. Ideally, mix the new food with the old food gradually over approximately one week. Also follow the feeding guidelines on the packaging and adjust the portion to suit your individual cat.

Why it suits this profile: For anyone looking for a recipe with a clearly detailed ingredients list and cod as a prominent source.
The ingredients list states 27% fresh cod and 26% dehydrated cod. However, the recipe does contain spelt and oats, so “fish” does not mean grain-free in this case.

Why it suits this profile: Designed for households with an adult, neutered cat that use a larger bag of food.

Not automatically. Check the life stage, nutritional status and ingredients. Cats with a known sensitivity to fish require different advice. If problems persist or your cat needs a special diet, it is advisable to consult a vet.
That depends on your cat and its daily diet. Wet food usually contains more moisture, while dry food is convenient to store and weigh out. A combination can work, provided you monitor the total portion and both products are suitable as complete food.
Follow the feeding guidelines on the packaging. Tuna or salmon treats are complementary and count as extras on top of the main meal. If you use fish-based food every day, preferably choose complete cat food that suits your cat’s age and condition.
