Buying pet food online: how to choose the right food and avoid marketing traps

Buying pet food online seems simple: choose a brand, compare the price, and place your order. However, attractive packaging and general claims can lead you to choose a food that isn't a good match for your pet's age, size, or daily routine. This can result in waste, extra costs, or a difficult switch to a different food.

This practical checklist helps you avoid the most common buying mistakes when it comes to cat food, dog food, puppy food, and kitten food.

Three common pitfalls when buying pet food

1. Confusing an appealing flavour with a complete meal

Words like chicken, turkey, or fish on the front of the pack don't automatically tell you how much of that ingredient is in the product. That's why you should always check the composition on the label. For some products, the percentage of chicken or turkey listed might only apply to specific kibble or pieces, not the entire product.

A multipack may also contain different recipes. This is handy for variety, but you should check that each variety is labelled as complete pet food. A complementary product is not intended to be a complete daily diet.

2. Ignoring age and size

A kitten has different nutritional needs from an adult cat. The same goes for puppies and adult dogs. So, look out for terms like kitten food, puppy food, adult, or senior. For dog food, you should also consider the dog's expected size. A large bag isn't automatically a good deal if the kibble size or nutritional value isn't suitable for your dog.

For example, the product description for Felix Double as Nice Junior states that the food is intended for kittens from 6 to 52 weeks old. According to its product information, Felix Double the Tasty Senior is aimed at cats aged 7 and over. Use these age indicators as a first filter, but always compare them with the guidelines on the packaging.

3. Only looking at the price per kilo

A large bag of dry food often has a lower price per kilogram, but wet food is sold in smaller portions and can therefore seem more expensive. Don't just compare the packaging; also consider:

  • the daily feeding amount;
  • the net weight;
  • the number of servings;
  • the shelf life after opening;
  • any delivery costs;
  • the amount of food your pet actually needs.

With wet food for cats or dogs, you also need to consider fridge storage. Many packages advise using opened portions within a maximum of two days.

The most important specifications to check

1. Does it say "complete food"?

Look for a clear indication such as complete and balanced pet food or "complete pet food". According to their product descriptions, Felix Double as Nice for adult cats, Cesar Adult Wet Dog Food, and Sheba Delicacies in Jelly are all complete foods for their specified target group.

Note that "complete" is always linked to a species and life stage. Cat food is not suitable for dogs, and puppy food is not automatically suitable for an adult dog. If in doubt, you can consult the brand's feeding guide or a vet.

2. Check the composition and analytical constituents

The ingredients list shows which raw materials have been used. The analytical constituents show the percentage of protein, fat, fibre, crude ash, and moisture, among other things. These figures are useful for making a fairer comparison between dry and wet food.

Wet food usually contains a lot of moisture. This makes the protein percentage on the label appear lower than that of dry food, so you can't directly compare the two products based on that single figure. Also, check for the presence of taurine in cat food and look at the nutritional additives listed on the label.

Claims about things like coat, digestion, or natural immunity are brand claims. According to the brand's own research or information, certain ingredients may contribute to these benefits, but these are not guaranteed effects. For example, the product description for Iams mentions a fibre blend and omega-3 and omega-6 fatty acids; this is information from the manufacturer, not a personal guarantee.

3. Adjust the portion size to your pet

Feeding recommendations are usually based on weight, age, and activity level. An active dog may need a different amount than a less active dog of the same weight. Treats count towards the daily energy intake.

When switching to a different food, a gradual transition over several days is advisable. This also allows you to better monitor how your pet reacts to the new food. Always provide plenty of fresh drinking water and store pet food according to the instructions on the packaging.

Wet food, dry food, or a multipack?

Dry cat food is easy to portion out and practical if you're not at home during the day. Store an opened bag sealed in a cool, dry place. Wet cat food is often sold in single servings and can be a good choice for cats that enjoy different textures or flavours. A multipack, such as Gourmet Gold Mousse Turkey Multipack or SHEBA Delicacies in Jelly Turkey & Chicken Multipack, offers variety without you having to order multiple separate boxes.

For dogs, a multipack of Cesar Adult Wet Dog Food can be a great option if you want to serve small portions. For a medium or large dog, a bag of dry food like Eukanuba or Orijen is often more straightforward for daily use. Always compare the portion size with your dog's weight.

Frequently asked questions about buying pet food online

Is buying pet food online cheaper?

It depends on the size, daily portion, special offers, and delivery costs. Compare the price per kilogram as well as the estimated cost per day. With multipacks, the price per serving can be clearer than with individual packs.

How long can you store opened pet food?

Dry food generally stays fresh for longer when stored in a well-sealed container in a dry place. According to most product labels, opened wet food should be covered, stored in the fridge, and used within a maximum of two days. Always follow the instructions on the packaging.

Can I switch to a different cat or dog food without any issues?

A gradual transition over several days is usually more advisable than an immediate switch. Mix a little more of the new food with the old each day, and keep an eye on your pet's appetite, stools, and general reaction. If you notice any persistent problems or if your pet is on a special diet, consult your vet.
