Choosing cat food with fish: watch out for these differences before you buy

Cat food with fish may seem easy to compare at first glance. However, a prominent flavour on the packaging can give a different impression from the ingredients list. If it says “with salmon” or “with tuna”, this does not automatically mean that fish is the main ingredient. The difference between complete food and a complementary product is also regularly overlooked.

Three common pitfalls when buying cat food with fish

1. A fish flavour does not always mean there is much fish

Always check the composition and the percentage of fish. For example, Felix Double the Tasty Salmon, Sea Fish & Beetroot lists fish and fish derivatives, but also specifies that the total product contains 1.7% salmon and 1.7% sea fish. This is more transparent than simply showing a large fish on the packaging.

Gourmet Mon Petit Intense Tuna, Salmon & Trout lists 4% of each named fish species per recipe. So do not just look at the name; check the order of the ingredients and the percentages too.

2. Wet food, snacks and complete food are not the same

Complete cat food is intended as daily nutrition in line with the feeding guidelines on the label. A complementary product may provide moisture or variety, but it will not supply all the nutrients your cat needs.

For example, INABA Broth Chicken with Tuna Recipe is a complementary product containing 93% water. It is suitable as a treat or a way to provide extra moisture, but not as a complete meal. If you are specifically looking for wet cat food with fish, look for the wording “complete pet food” or “complete feed”.

3. “Grain-free” is not automatically right for every cat

Grain-free cat food can be a personal choice, but grain-free nutrition is not necessary for every cat. More important is whether the composition suits your cat’s life stage, activity level and any food sensitivities.

According to the product description, Farmina N&D Ocean Kitten Cod is offered as grain-free kitten food. The adult version, Farmina N&D Ocean Cod, contains spelt and oats instead. So check the ingredients for each product rather than relying solely on the brand or flavour.

Which specifications should you check?

1. Life stage and nutritional status

A kitten has different nutritional needs from an adult cat. Kitten food with fish should clearly be suitable for kittens and list the feeding guidelines on the packaging. According to the product description, Iams Cat Kitten Ocean Fish 3 kg is intended for kittens and contains, among other things, DHA, taurine, vitamin D and minerals.

For cats from around one year old, choose cat food for adult cats. Iams Cat Adult Tuna and Iams Cat Adult Ocean Fish are dry foods for adult cats. With a large 10 kg bag, also consider the use-by date, storage space and the amount your cat actually eats each day.

2. Dry food or wet food

Dry cat food with fish is practical to portion and remains usable for longer after opening when properly sealed. Check the nutritional value per 100 grams and follow the portion table. For example, Felix Seaside Sensations gives a guideline of 70 grams per day for a 4 kg cat fed exclusively on dry food.

Wet cat food with fish generally contains more moisture and is available as pâté, mousse, chunks in gravy or broth. A small pack is useful when your cat has several fresh meals a day. Once opened, wet food should be stored in the fridge and used within the stated period, according to the product instructions.

3. Portion size and packaging

Cat food in small portions helps limit leftovers and makes it easier to divide the daily amount between several meals. Gourmet Mon Petit Intense Tuna, Salmon & Trout comes in 50-gram pouches. Gourmet Mon Petit Intense Duo Meat & Fish Mix also contains six 50-gram portions.

A cat food multipack can be good value for households with a cat that enjoys a particular flavour. However, check that all the varieties are suitable for your cat and whether the pack contains a mixture of complete and complementary food.

Frequently asked questions about cat food with fish

Is cat food with fish suitable as a daily diet?

It can be, as long as the packaging states that it is complete food for the correct life stage. A complementary product, such as broth with tuna, is not intended to be the only meal. Always follow the portion table and provide fresh drinking water.

Is wet food better than dry food for cats?

Wet food generally contains more moisture, while dry food is easy to store and weigh out. Many cat owners combine both types. Adjust the quantities accordingly to prevent overfeeding and consider your cat’s individual needs.

How do you switch to new cat food with fish?

Gradually mix the new food into the old food over approximately one week. Start with a small amount and increase it step by step. Stop if persistent gastrointestinal problems occur and ask a vet for advice. The feeding guidelines on the packaging remain the main point of reference.
