Choosing Cat Food Without the Wrong Purchase: A Practical Guide for Every Cat

The choice of cat food is vast: from wet cat food in sauce to dry cat food for a specific life stage or need. An attractive packet alone doesn't tell you enough. The difference is often in the small print: is the food complete, what age is it intended for, and how much do you feed per day?

Three Common Pitfalls When Buying Cat Food

1. A Flavour Name Doesn't Tell You How Much Meat Is In It

On the front, you might see “chicken”, “salmon” or “beef” in large letters. Always check the ingredients list. In different varieties of Gourmet Gold, for example, 4% of the named ingredient is stated. The rest consists of meat and animal derivatives, minerals and vegetable derivatives.

So a flavour name is not the same as a high proportion of that flavour. Look at the full ingredients list and the analytical constituents.

2. “Complete” and “Complementary” Are Confused

Complete food is intended as a daily meal according to the feeding guidelines on the packaging. Complementary food is an extra and does not replace a full meal. Felix Soup Fish, for example, is described in the product information as a complementary food for adult cats. The advice is one pouch per 4 kg of body weight per day, alongside a complete food.

A multipack with lots of variety is handy, but first check the legal food type.

3. A Formula for a Specific Need Is Not a Treatment

Words like “sensitive”, “indoor”, “sterilised” or “urinary” describe a nutritional direction. They are not a guarantee of a particular result. With Purina One Sensitive, the manufacturer states, for example, that the formula is intended for adult cats with a sensitive digestion and contains no added wheat. The claim of 24% less odour from firm stools in 14 days is based on Purina's own research.

Does your cat have recurring issues, difficulty urinating, weight problems or a food allergy? Discuss the diet with a vet rather than using a special formula as a treatment on your own.

Important Points to Check

1. Age and Life Stage

Kittens have different nutritional needs to adult cats. Choose kitten food from weaning until the age stated on the label. Purina One Junior Kitten is described in the product information as suitable from weaning up to 12 months and also for pregnant or nursing cats. The packaging mentions DHA and adapted nutrients for the growth phase.

For an adult cat of one year or older, varieties such as adult cat food, indoor food or food for neutered cats are more logical. Don't automatically give a kitten adult cat food just because the taste is well accepted.

2. Wet Food, Dry Food and the Daily Amount

Wet cat food usually contains a lot of moisture and is available in tins, trays or pouches. This can be practical for cats that like to eat several small meals. Gourmet Mon Petit, for example, comes in 50-gram portions. According to the product information, once opened it should be covered, refrigerated and used within two days.

Dry cat food is easier to store and often practical to portion by the gram. Do pay attention to the energy content and weigh the portion. A guideline for a 4 kg cat is only a starting point: activity, age, body condition and any neutering all affect the requirement.

3. Ingredients, Grains and Specific Formulas

Grain-free cat food is not automatically more suitable for every cat. Look at the full recipe and the reason you are choosing it. Farmina N&D Quinoa Cat Digestion Lamb is described in the product description as a grain-free complete food with lamb, herring meal, quinoa and peas. The manufacturer mentions more than 90% animal protein; always check the label for the most up-to-date information.

For cats with a sensitive stomach, a simple switch can help, but change the food gradually over about seven days. Keep an eye on stools, appetite and weight. If problems persist, veterinary advice is needed.

Frequently Asked Questions About Cat Food

What is suitable cat food for a sensitive stomach?

Choose a complete formula where the ingredients and target group are clearly stated. A product like Purina One Sensitive Adult can suit an adult cat for which you are looking for a recipe without added wheat. Introduce new food gradually and ask a vet for advice if problems persist.

Is wet or dry cat food better value?

That depends on the brand, packaging and daily amount. A cat food multipack can lower the price per portion, while dry food is often more shelf-stable once opened. So compare the price per 100 grams and the recommended number of grams or pouches per day.

How long does opened wet food keep?

Always follow the packaging. The products mentioned generally advise storing opened wet food covered in the fridge and using it within 24 hours to two days. Don't leave leftovers at room temperature for long and serve wet food at room temperature if possible.
