Gear Score Methodology

PetPal Gear Score

Best Hypoallergenic Cat Food (2026)

View full buying guide →

This guide is an editorial synthesis. We read the Mueller, Olivry, and Prelaud systematic review of feline food allergens, Tufts Cummings Petfoodology, the Cornell Feline Health Center, Today's Veterinary Practice, the Merck Veterinary Manual, and AAFCO labeling rules. We also read manufacturer documentation and verified buyer review sentiment. We did no first-hand product testing. PetPalHQ does not run a testing lab. This guide does not diagnose a food allergy. It does not replace a vet visit.

Allergen-Avoidance Score = (Protein Simplicity & Novelty × 0.35) + (Clean Label & Carbohydrate Control × 0.25) + (Digestive & Skin Support × 0.25) + (Availability, Value & Acceptance × 0.15)

Factor breakdown

Protein Simplicity & Novelty

35%

How cleanly the recipe limits its animal-protein sources. We also weigh whether that protein is genuinely novel for most cats. Rabbit, duck, and venison are uncommon. Chicken, beef, and fish are common triggers. The Mueller review names beef, fish, and chicken as the top reported cat allergens. One named protein with no hidden meat meals scores highest. Fewer and less familiar proteins shrink the field of possible triggers. That is why the duck and rabbit picks lead and the chicken and salmon picks rank lower.

Clean Label & Carbohydrate Control

25%

The length and honesty of the full ingredient deck beyond protein. We look for one clearly named carbohydrate. We want no corn, wheat, soy, or artificial colors. We check for a real AAFCO complete-and-balanced statement. Shorter, fully disclosed labels score higher. A shorter list means fewer co-ingredients that could provoke or confuse a sensitive cat.

Digestive & Skin Support

25%

The functional extras that help the cats sending owners shopping. Those are the cats with loose stool, vomiting, or itchy skin. We reward guaranteed live probiotics or prebiotic fiber. We reward an omega balance for coat and high digestibility. We weight published maker data and vet-nutrition coverage over marketing. We also treat wet formats kindly for the water they add to urinary-prone cats.

Availability, Value & Acceptance

15%

Whether the food is genuinely buyable over the counter on Amazon, not prescription-gated. We judge price per pound across bag sizes. We reward formats finicky cats will actually eat. We reward a stable, widely stocked product line. Prescription hydrolyzed diets are left out of this score. We cover them separately as vet-directed options.
