Buying cat and dog food: how to choose the right nutrition for your pet

Buying cat and dog food might seem straightforward – until you have to choose between dry food, wet food, grain-free recipes, multipacks and food for a specific life stage. A flashy packet doesn’t always tell the full story. The ingredients, the nutritional purpose and the correct portion size matter far more than marketing jargon.

As a Joybuy Product Recommendation Officer, I filter product information down to the practical details: which animals and ages the food is intended for, whether it’s a complete food, and what verifiable features are listed on the label.

Three common pitfalls with pet food

1. A high percentage sounds clearer than it really is

Brands sometimes quote a percentage of chicken, fish or animal ingredients. Always check what that percentage refers to: the total product, a specific kibble or a particular blend of ingredients. In dog food with chicken, for example, both fresh chicken and chicken meal may be listed. These are different ingredients with different moisture levels.

2. Grain-free doesn’t automatically mean suitable

Grain-free dog food can be a good fit if you want to avoid grains, but it’s not a universal mark of quality. Also look at the protein and fat content, the energy per kilogram, and whether it’s suitable for your pet’s age and activity level. An active dog may have very different nutritional needs from a laid-back house dog.

3. “Complete” is confused with “right for every situation”

Complete food is formulated as a daily diet according to the product information. That doesn’t mean every recipe is suitable for kittens, puppies, seniors or animals with specific dietary requirements. Urinary care cat food, for instance, is intended for adult cats according to the label. If your pet has urinary tract issues, a vet should guide your choice of food.

Which specifications should you check?

Species, age and life stage

Start with the basics:

  • Kitten food is designed for young cats; check the stated age range, such as 6 to 52 weeks.
  • Senior cat food is tailored to older cats according to the product details.
  • Puppy food must match the growth stage and, where stated, the breed or eventual size.
  • Adult dog food should suit your dog’s weight, activity level and breed size.
  • Check whether the packaging says “complete food” or “complementary food”.

Analytical constituents

Compare at least crude protein, fat, fibre, ash and moisture. Dry food usually has a low moisture content, whereas wet food contains a lot of moisture. This means you can’t directly compare protein percentages in dry and wet food without accounting for the moisture level.

Examples from product information:

  • Iams cat adult chicken 10kg states 87% animal protein according to the brand description, and contains omega 3 and 6, taurine and a fibre blend.
  • Acana Active & Agile Dog Food states 33% crude protein, 19% fat and 12% moisture per 100 grams.
  • Orijen Original Prey Dog Food states 38% crude protein and 18% fat.

Claims about the origin or function of nutrients come from the brands’ product information. Treat them as product specifications, not medical guarantees.

Packaging, portion size and shelf life

A 10 kg or 17 kg bag might look like good value, but it’s only practical if your pet happily eats that food and you can store it airtight. Pay attention to:

  • the recommended daily amount;
  • your pet’s body weight and activity level;
  • resealable packaging;
  • storage in a cool, dry place;
  • the shelf life after opening;
  • how long opened wet food keeps in the fridge.

When introducing a new food, a gradual transition of around seven to ten days is sensible if the product information recommends it. This way you can keep a closer eye on how your pet responds to the change.

We’ve put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.

Dry food, wet food or a combination?

Dry cat food is easy to portion and store. Large bags, such as 10 kg, can be handy for multi-cat households, but always seal the bag properly. Wet cat food is often sold in individual portions and can be suitable for cats that prefer softer food. Check whether it’s a complete food.

For dogs, you can combine dry food with wet food as long as you adjust the total daily amount accordingly. Products like CESAR Adult Wet Dog Food are, according to the product information, complete wet food for adult dogs. Don’t automatically give a full portion of wet food on top of the usual amount of dry food.

Frequently asked questions about cat and dog food online

How much does cat and dog food cost online on average?

The price depends on the brand, recipe, pack size and species. Work out the cost per kilogram and compare that with the recommended daily amount. A larger pack doesn’t always mean lower overall risk: you may pay more upfront and need to keep the food fresh for longer.

How long can you store an opened bag of dry food?

Always follow the shelf-life information on the packaging. Store dry food in a cool, dry place and keep it well sealed. Don’t buy a bigger bag than you can use within a reasonable time. Wet food should be refrigerated after opening according to the product instructions; several products mentioned advise using it within 48 hours.

When should you switch to senior cat food or puppy food?

Use the age indication on the label as a guide. Felix Junior is, according to the product information, intended for kittens from 6 to 52 weeks, while Felix Senior is intended for cats from 7 years old. For puppies, the switch-over point varies by breed size. If you’re unsure about growth, weight or a medical condition, it’s wise to consult a vet.
