Cat food reviews in 2026 should prioritize nutritional adequacy, life-stage fit, manufacturing evidence, and current safety notices—not "premium" claims. Recent nutrient testing, thiamine recalls, and H5N1 contamination show why shoppers must look beyond protein percentages and advertising. A "complete and balanced" food is intended to supply a cat's full diet when it meets an AAFCO nutrient profile or passes AAFCO feeding trials. Its adequacy statement must also match the cat's life stage.

Is the food suitable as a sole diet?
Find the nutritional adequacy statement before comparing ingredients or flavors. A food intended for occasional or supplemental feeding should not replace a complete and balanced daily diet. Check whether the statement covers your cat's life stage. An adult-maintenance claim does not establish that the food meets the needs of every life stage.
Wet and dry percentages also require adjustment before comparison. The FDA's pet-food guidance notes that canned food is typically 75–78% moisture, while dry food is typically 10–12% moisture. Convert nutrients to a dry-matter basis: For example, a food with 10% protein and 78% moisture contains about 45.5% protein on a dry-matter basis. A dry food with 30% protein and 10% moisture contains about 33.3% on that basis.
- Subtract the moisture percentage from 100 to find the dry-matter percentage.
- Divide the listed nutrient percentage by the dry-matter percentage.
- Multiply by 100.
What does recent nutrient testing show?
A 2025 laboratory analysis published in Veterinary Research Communications examined 27 commercial dry cat foods. Every product met FEDIAF adult minimums for protein and fat, but 11% fell below the linoleic-acid minimum and 14% lacked arachidonic acid. The result does not establish that dry food generally is deficient.
The study covered only 27 dry products, so it cannot represent every brand, formula, production lot, or wet food. It does show the weakness of judging a product from headline protein and fat figures alone. Essential fatty acids and other nutrients matter even when the most visible numbers meet minimums.
Do "low-carb," "premium," and "holistic" claims help?
"Low-carb" is not an established universal weight-control advantage. A 2025 Journal of Animal Science meta-analysis found that dietary carbohydrate concentration did not increase cats' body fat or fasting insulin and glucose. That finding does not prove every carbohydrate level suits every cat.
It means the label claim alone cannot predict weight outcomes for all cats. WSAVA advises that "premium" and "holistic" are unregulated marketing terms with little value for nutritional assessment. More useful questions concern substance rather than branding:.
- Does the company employ qualified nutritionists?
- Does it analyze finished products?
- What quality-control procedures does it use?
- Has it published relevant research?
Which 2026 thiamine alert requires action?
The major documented 2026 update involves Quest Cat Food. FDA testing found extremely low or undetectable thiamine in all eight tested lots, despite labeling that represented the food as adequate for all life stages.
Continued sole feeding can cause severe thiamine deficiency and death. FDA's recall list records Go Raw/Steve's Real Food recalls dated February 26 and June 8, 2026, covering Quest frozen and freeze-dried chicken cat-food products because of potentially low thiamine. If you have a potentially affected product:.
- Stop feeding it.
- Check the package and lot details against the FDA advisory and recall list.
- Contact a veterinarian, especially if the food has been the cat's sole diet.
Why raw poultry needs extra scrutiny
Raw and unpasteurized animal ingredients create a separate safety issue. The FDA linked RAWR Raw Cat Food Chicken Eats lots CCS 25 077 and CCS 25 093 to H5N1-positive product and to a cat euthanized after illness. Genome sequencing indicated a common contamination source.
FDA requires covered manufacturers using uncooked or unpasteurized poultry or cattle ingredients to reassess their H5N1 safety plans. Cats can develop severe or fatal illness after exposure to contaminated raw meat, milk, or eggs that have not undergone virus-inactivating processing. When reviewing a raw product, identify whether its ingredients receive a virus-inactivating treatment and check its exact lot against current FDA notices. Stop feeding lots CCS 25 077 and CCS 25 093 and contact a veterinarian if a cat consumed them.
