Choosing Cat Food: How to Compare Complete Diets, Wet Food and Treats Without Making a Costly Mistake

A bag of cat food might seem straightforward to choose at first glance. Yet the wrong purchase can quickly lead to waste, a cat that turns its nose up at dinner, or a feeding plan that doesn't suit its life stage. Especially with kitten food, wet cat food and cat treats, the claims on the packaging can sometimes be made to sound more important than the basic information you really need.

Three common pitfalls to watch out for:

• Confusing a treat with a complete cat food. Products like creamy treats, broths and cat snacks are usually complementary foods. They are not intended as a daily main meal.
• Only looking at the flavour name. "With chicken" or "with fish" doesn't automatically tell you how much chicken or fish is actually in it. Always check the ingredients list and the stated percentage.
• Buying a bulk pack without a transition plan. A large bag of dry food might seem like good value, but your cat could refuse the new food or suffer from a sudden change. So, introduce any change gradually, for example over around seven days if the product information advises it.

What Information on the Label Really Counts

1. Check Whether It's a Complete or Complementary Food

First, look for the legal description. "Complete pet food" means the product can be given as a main food for the stated species and life stage, according to the instructions for use. If it says "complementary pet food", then it's a supplementary food.

This difference matters for:

• Dry cat food used as a daily staple;
• wet cat food used as a main meal;
• kitten food for growing cats;
• cat treats and cat snacks;
• hydrating cat snacks and toppers.

For example, INABA CHURU CAT Chicken states that it is a complementary food. According to the product information, the composition contains 90.5% moisture and 6 calories per treat. That makes it suitable as a snack or topper, but not as a replacement for a complete food. The same applies to INABA Bisque Cat Chicken Recipe and the INABA Fun Bites varieties.

2. Look at the Life Stage and Nutritional Purpose

A kitten has different nutritional needs to an adult cat. So, check whether the packaging states that the food is suitable for kittens, adult cats, or multiple life stages.

The product information for Purina One Junior Kitten Food Chicken & Grain Formula 800g states use from weaning up to 12 months, and for pregnant or nursing cats. Farmina N&D Ocean Kitten Cod is described as a complete food for kittens and for pregnant or nursing cats. For both products, you need to adjust the portion according to age, weight and activity.

Also pay attention to the transition. Gradually mix the new and old food, and keep an eye on your cat's stools, appetite and body condition. If problems persist, it's wise to seek advice from a vet.

3. Assess Moisture, Composition and Portions Together

Wet food generally contains more moisture than dry food. That can be handy for cats that don't drink much, but a high moisture percentage doesn't automatically mean the product is a complete food. For instance, INABA Fun Bites Cat Chicken Wraps Tuna states 93% moisture, but it is a complementary food.

So, always compare:

• Moisture percentage: relevant when you're looking for wet food or hydrating cat snacks;
• protein and fat: look at these values in relation to the energy content;
• ingredient order: ingredients are usually listed in descending order by weight;
• daily amount: treats must be counted alongside the main food;
• storage advice: opened portions often need to be refrigerated and used within a short time.

"Grain-free cat food" might be a preference for some households, but grain-free on its own is no guarantee of a better choice. Look at the complete composition and its suitability for your cat.

Frequently Asked Questions About Cat Food

What's the difference between wet food and dry food for cats?

Wet food usually contains more moisture and is often sold in individual portions. Dry food has a longer shelf life once opened and is easy to measure out. The right choice depends on your cat's preference, your feeding schedule, and whether the product is labelled as complete. You can combine both, as long as you adjust the total daily amount.

How often should you feed kitten food?

Follow the guidelines on the packaging and divide the daily portion into several meals for young kittens. The amount will change as your kitten gets heavier and more active. Use treats sparingly and deduct them from the total food allowance.

Are cat treats necessary for a healthy diet?

No. Cat treats are supplementary and not necessary when the main food is complete. However, they can be used as a reward or topper. Always check the portion size, composition and storage instructions, especially for hydrating cat snacks and soft products.
