10 Questions to Ask Before Buying Cat Food

By Dr Duncan Houston

A bag of cat food can look reassuring long before it tells you anything useful. Pictures of fresh meat, a long ingredient list and words such as “premium” all compete for attention. The more practical question is whether the manufacturer can explain the exact food you are considering.

Start with the label, then ask for the missing details in writing. This guide helps you compare answers without needing to become a food formulator or choosing by price and packaging alone.

Quick Answer

Choose cat food by its nutritional adequacy statement, suitability for your cat's life stage, formulation expertise and quality-control information. Ask the manufacturer about the specific recipe, its calorie content, testing, storage and traceability. An ingredient list or a claim of “AAFCO approval” is not enough to establish that a food is a suitable main diet.

Start with the exact product

Photograph the front and back of the package, including the recipe name, life-stage wording and calorie information. A company may sell complete meals, complementary foods and treats under the same brand. An answer about its products in general may not answer your question about one pouch.

If your cat already has a veterinary feeding plan, bring that plan into the comparison. Manufacturer information can help you understand a product; it does not decide whether to replace a prescribed diet.

Ten useful questions for the manufacturer

1. Is this recipe intended to be a complete main diet?

Ask where the nutritional adequacy statement appears and which species and life stage it covers. A topper can look very similar to a meal. “For intermittent or supplemental feeding” means you need to understand its limited role before treating it as the whole diet.

2. What does the adequacy statement actually mean?

For foods sold in the United States, ask whether the claim is supported by an AAFCO nutrient profile or feeding tests using AAFCO procedures. The FDA explains these two routes. AAFCO does not provide a simple brand-approval stamp. Ask about the recipe's evidence rather than accepting that shorthand.

3. Who is responsible for formulation?

Request the formulator's qualifications and role. Who develops the recipe, checks changes and answers technical questions? The useful detail is relevant training and responsibility for the product, rather than a photograph of an unnamed expert on the website.

4. What testing is performed on the finished food?

Ask what is measured after production, how often testing occurs and how the company checks consistency. A recipe calculated on paper and the food in a finished package are different stages of the process. Clear answers should distinguish formulation, nutritional analysis and any feeding research.

5. How are ingredients and suppliers checked?

Ask about supplier approval, ingredient specifications and what happens when a shipment does not meet them. Country of origin is useful traceability information, but it cannot by itself rank ingredient quality. “Locally sourced” still needs a meaningful quality-control explanation.

6. Can you provide information beyond the ingredient list?

Request a typical nutrient analysis and ask which basis is being used, such as as-fed or dry matter. Keep the units with the figures. Comparing one wet food's as-fed percentage with another food's dry-matter value can produce a misleading ranking.

7. How many calories are in the amount I will actually serve?

Ask for calories per pouch, can or measured weight, as applicable. Package size is not a dependable way to compare feeding cost. Record the calorie information alongside the price and your cat's existing feeding plan, rather than assuming that two similar-looking portions are equivalent.

8. How can a batch be traced if there is a problem?

Find the lot code, best-before date and contact details before discarding the packaging. Ask how the company investigates complaints and communicates recalls. A useful response explains the process and gives a contact route that works for customers in your country.

9. What changes after the package is opened?

Ask about storage, refrigeration where required, resealing and the manufacturer's use-after-opening instructions. Check whether those directions differ for a rehydrated product. Do not substitute a shelf-life claim for an unopened bag for instructions about food that is already open.

10. Can you explain your marketing claims in concrete terms?

Ask what a sustainability, welfare or quality claim measures, who verifies it and whether it applies to this recipe. Keep those priorities alongside nutritional suitability. One appealing environmental claim does not answer the rest of the food-selection questions.

How to interpret the answers

• Useful answer: identifies the recipe, provides units and explains who is responsible for the information.
• Needs clarification: discusses the brand generally, mixes units or sends a promotional brochure without addressing the question.
• Pause before choosing: the food's intended feeding role remains unclear or the manufacturer cannot explain the claim you are relying on.

You do not need every confidential manufacturing detail. You do need enough understandable information to compare the food and discuss unresolved questions with your veterinary team.

A comparison you can finish before buying

Shortlist two or three realistic options. For each, record the exact recipe, feeding role, life stage, calorie information, pack price, storage needs and unanswered questions. Save the manufacturer's reply with the date. That small record is more useful than repeatedly searching for a universal “best cat food.”

The WSAVA food-selection guide provides a useful framework for questions about expertise, quality control and label information.

Common mistakes to avoid

• Assuming a food is superior because meat appears first or because it contains no by-products
• Using “premium,” “natural” or “holistic” as a substitute for the adequacy statement
• Comparing nutrient percentages without checking the units and moisture basis
• Treating every product sold by a familiar brand as a complete meal
• Buying a large supply before confirming the storage requirements and suitability

Frequently Asked Questions

Does AAFCO approve cat-food brands?

No. Look for the specific nutritional adequacy statement and how it is substantiated, rather than a general claim that a brand is approved.

Are by-products automatically poor-quality ingredients?

No. Ingredient names alone do not establish the quality or overall nutritional value of the finished food. Ask about formulation and quality control.

Is a food made with feeding trials always the best choice?

The testing method is useful information, but it is one part of the assessment. Suitability for the cat, the recipe, formulation and quality control still matter.

What if the company will not answer?

Record what remains unknown, ask the veterinary team which details matter for your cat and compare a product whose intended use and supporting information are clearer.

Choose information you can use

A good food comparison ends with a clear reason for your choice. Keep the label and the answers, understand the product's feeding role and take unresolved suitability questions to your veterinary team before changing an established feeding plan.
