Buying fish products and cat food online: how to choose wisely and avoid costly mistakes

Buying fish products and cat food online might seem straightforward, but product pages can hide important differences. A packet labelled “salmon” doesn’t always tell you how much salmon is actually inside. And with cat food, an appealing flavour name doesn’t necessarily mean it’s complete wet food for adult cats.

With these practical checks, you can compare frozen fish, fish products and Gourmet cat food based on verifiable information.

Common pitfalls when shopping online

1. The product name doesn’t always tell the full story

An item with “cod” or “cod fillet” in its name may, according to the ingredients list, contain a different white fish. For example, Vismarine Cod Fillets lists Alaska pollock as an ingredient, along with rapeseed oil, wheat flour, water, potato starch and salt. Always check the full composition, not just the title.

The same applies to pangasius fillet, tilapia fillet and panga. Pay attention to the fish species, origin, added ingredients and net weight.

2. “With salmon” doesn’t automatically mean a high salmon content

With Gourmet Mon Petit, each variant states 4% tuna, salmon or trout. That’s clear information, but the product also contains meat and animal derivatives, vegetable protein extracts, minerals, sugar and yeast. If you’re specifically looking for a fish-rich meal, you need to look beyond the flavour name.

For regular fish products, the percentage of fish is just as important. According to the product information, the NordicSeafood pangasius fillet contains 80% fish, water, water-retaining agents and salt. The Panga Fillet 200/+, on the other hand, is described as 100% panga.

3. Packaging and storage instructions are often overlooked

Ordering frozen fish requires enough space in your freezer. Check beforehand whether you need a 250g, 400g, 525g, 800g pack or a multipack. A large pack isn’t automatically better value if you can’t use it all in time.

Frozen fish must stay frozen until use. After defrosting, it should be kept chilled and used within the stated period. Do not refreeze after defrosting is an important instruction that appears on several products.

Key parameters for fish and cat food

Fish species, ingredients and allergens

Fish naturally contains the allergen fish. Some prepared products also contain wheat or gluten. According to the product information, Vismarine kibbeling consists of 58% Alaska pollock and contains wheat flour and wheat starch, among other ingredients. For Vismarine Cod Fillets, fish, wheat and gluten are explicitly listed.

If you have an allergy or dietary requirement, check the ingredients list on the packaging. Information about the 14 main EU allergens can vary from product to product and should always be verified against the current label.

Net quantity and portion size

Compare prices based on the price per 100g or per kilogram. A single salmon fillet of 250g is suitable for a small meal or to pair with vegetables. A pack of 3 x 250g is more practical if you eat fish regularly. For a household looking to stock up, 800g of tilapia or 2 x 800g of panga might make more sense.

With smoked salmon, the packaging is often smaller. The sliced smoked salmon at 200g contains, according to the product specification, 96% salmon, salt, buffered vinegar, sugar and smoke.

For cat food: complete, life stage and texture

Look for the label complete food for adult cats. This means the product is intended, according to the product information, as a complete diet for the stated life stage. Also check the age indication: the Gourmet products below are intended for adult cats, typically from one year old.

Texture also matters. There are varieties in sauce, mousse, fine chunks and mini-fillets. A cat food multipack is handy for variety, but check that all the flavours suit what your cat is used to. According to the manufacturer’s feeding information, the recommended amount varies by weight, activity and condition. Use the guideline on the packaging as a starting point and always provide fresh drinking water.

Frequently asked questions

How can I safely order frozen fish?

Check that it clearly states the product is stored and transported frozen. On receipt, check that the packaging is intact and the product still feels frozen. Store it immediately at the stated freezer temperature. Only defrost the amount you need and do not refreeze defrosted fish.

What’s the difference between wet cat food and complete cat food?

Wet cat food describes the form of the product. “Complete cat food for adult cats” indicates that, according to the label, the product is intended as a complete diet for that life stage. Check this label when you’re looking for a main meal rather than a supplementary treat.

How long does opened cat food keep?

Always follow the packaging. For Gourmet Mon Petit, it states that an opened pouch should be covered and stored in the fridge, and used within two days. For tinned varieties, the timeframe may differ. Serve wet food at room temperature and discard any leftovers according to the usage instructions.
