Cat food: how to choose the right diet without blowing your budget

Choosing a cat food isn’t just about looking at the flavour on the packet or the number of sachets in a multipack. For an adult cat, especially if it’s neutered and lives indoors, its lifestyle, daily portion and the food’s composition matter far more than the marketing promises printed on the packaging.

Here are the most common pitfalls:

  • Confusing complete food with complementary food: a product sold as a treat or accompaniment doesn’t necessarily cover all daily nutritional needs.
  • Only comparing the packet price: a 12 kg bag might look like a bargain, but you need to work out the price per kilogram and make sure your cat will finish it before the recommended date.
  • Relying on a single highlighted ingredient: the mention “with chicken” or “with salmon” doesn’t mean that ingredient makes up the whole recipe. Check the ingredients list and the percentages given.
  • Skipping the food transition: switching abruptly from one product to another can lead to refusal or digestive upset. A gradual transition over several days is usually recommended on the packaging.

The criteria to check before you buy

1. Age, neutering and activity level

A kitten doesn’t have the same needs as an adult cat. For an animal over a year old, choose a formula clearly labelled as adult cat food. If your cat is neutered or spayed, a dedicated recipe can help you manage its portions more effectively, especially if it doesn’t get much exercise.

An indoor cat often burns fewer calories than one that goes outside regularly. The portion should therefore be tailored to its weight, activity and body condition, without forgetting any veterinary recommendations. Food for neutered cats doesn’t give you free rein to fill the bowl as much as you like.

2. The “complete food” label

For everyday feeding, check that the packaging clearly states complete food for adult cats. This distinguishes foods designed to cover daily needs from complementary products.

Dry cat biscuits generally contain little water and have a higher energy density. Wet cat food, or moist cat food, provides more moisture and is often sold in individual portions. Both formats can be served separately or combined, as long as you adjust the quantities to avoid accidentally adding up the calories.

3. Analytical constituents, packaging and storage

Compare the levels of protein, fat, fibre, ash and moisture. These percentages aren’t read the same way for dry biscuits and wet food: wet food naturally contains much more water.

The packaging should also suit your consumption:

  • a 1 to 3 kg bag is handy for trying a recipe or limiting storage space;
  • a 6 to 12 kg bag can lower the price per kilogram in a household where the cat already eats that product regularly;
  • multipacks of cat food in sachets or tins make portioning easier, but always check the total quantity you’re actually buying.

After opening, seal the biscuit bag carefully and store it in a dry place. For wet food, put leftovers in the fridge and follow the time limit stated on the product, usually between 24 and 48 hours depending on the product.

Dry biscuits, wet food or a mixed diet?

Dry cat biscuits are easy to portion and simple to store. They suit households that prefer a hassle-free routine, as long as you always leave a bowl of fresh water available. Wet food is served in portions and may be better for cats that enjoy saucy, mousse or chunk textures.

A mixed diet lets you alternate between formats, but the portions stated on the packaging shouldn’t be added together as they are. For a neutered or less active cat, weigh the portions and check its body condition regularly. If your cat has a medical condition, significant overweight or a prescribed diet, ask a vet for advice before making any changes to its food.

FAQ on cat food

How much food should I give an adult cat?

The amount depends on weight, activity, age, neutering status and the type of food. Start by following the recommendations on the packaging, then adjust gradually. A portion of dry biscuits can’t be directly compared to a portion of wet food, because their water content is very different.

Can I keep a large bag of dry biscuits for several months?

Yes, as long as you seal the bag properly and store it in a cool, dry place away from sunlight. To preserve the aroma and quality of the biscuits, also avoid leaving the whole portion in a bowl exposed during the day. If needed, use a clean, airtight container.

Are multipacks of cat food always more economical?

Not necessarily. Calculate the price per kilogram and take the recommended daily portion into account. A multipack of wet food can reduce waste thanks to its individual portions. On the other hand, a large bag of dry biscuits is only really worthwhile if your cat likes the recipe and eats it regularly.
