Cat food with no additives
A cat food with genuinely no additives at all is rare, because vitamin and mineral premixes added to make a food nutritionally complete are legally classed as additives under UK and EU feed law, even though they are beneficial rather than cosmetic. What most owners actually mean by no additives is no artificial colours, flavours or preservatives, which is a narrower and more achievable claim.
What counts as an additive, technically
Feed law defines additives broadly: preservatives, colourings, flavourings, but also vitamins, trace elements and amino acids added to balance the nutrition of a complete food. A cat food without any added vitamins at all would struggle to be nutritionally complete, which is exactly what a cat needs it to be.
That technical definition is rarely what an owner has in mind when they search for a no-additive food. Most people mean something closer to no artificial extras used purely for colour, smell or shelf life, rather than a food stripped of every added nutrient.
What owners usually mean, and how to check for it
Look at the ingredients list for artificial colourings, listed as E-numbers or named dyes, and for chemical preservatives such as BHA or BHT, alongside artificial flavourings. Their absence is what most no-additive claims are actually pointing to, and it is checkable directly from the label rather than the marketing on the front.
Natural preservatives, such as vitamin E listed as a mixed tocopherol, are common in foods marketed this way and are generally considered a different category from synthetic chemical preservatives, though they still technically count as an additive in the strict legal sense.
Does it actually matter for your cat
There is no strong evidence that artificial colours or flavours in pet food cause harm at the levels used, and colour in particular exists mainly to appeal to the owner buying the food rather than the cat eating it, since cats have little interest in the colour of their dinner.
That said, some owners simply prefer to avoid artificial extras as a matter of principle, which is a reasonable personal choice rather than one based on a proven health risk, and plenty of good-quality foods are formulated without them either way.
Checking a food actually suits your cat
Avoiding artificial additives says nothing about whether a food is otherwise the right choice for your cat. Protein source, life stage suitability and how well your cat tolerates it day to day matter far more to their overall health than whether a preservative is natural or synthetic.
If your cat has a known sensitivity or a diagnosed condition, an additive-free label is not a substitute for checking the food is appropriate for that specific need, which is worth doing with your vet's input rather than relying on the front-of-pack claim alone.

Common questions
- Is added vitamin content in cat food a bad thing?
- No, quite the opposite. Added vitamins and minerals are what make a complete cat food nutritionally balanced, and a cat fed a diet without them would be missing nutrients they genuinely need, so this kind of additive is beneficial rather than something to avoid.
- Are natural preservatives better than artificial ones?
- They are generally preferred by owners looking to avoid synthetic chemicals, though both types are used at levels considered safe under UK and EU regulation. The choice often comes down to personal preference rather than a proven difference in safety.
- Why do some cat foods use artificial colouring at all?
- Colouring in pet food is mostly there to make the food look more appealing to the person buying it, since cats do not select food by colour the way people might. It has no established nutritional benefit either way.
- How can I tell if a cat food is genuinely additive-free?
- Read the ingredients list rather than relying on front-of-pack wording, checking specifically for artificial colours, flavours and chemical preservatives. Remember that added vitamins and minerals will still be listed, and their presence does not contradict a genuine no-artificial-additives claim.
