PlainPetFood publishes an editorial food-safety compilation. When the FDA or ASPCA Animal Poison Control Center names a food as dangerous, that food's page links the source; other ratings are identified as editorial guidance. Its cat rating, portion, preparation notes and warning signs are rendered from the food-safety archive; a named FDA or ASPCA source is linked above when that authority names this food. See our editorial standards & corrections policy, report a correction, the methodology behind these numbers, or contact the editorial team. Data current as of August 29, 2026.
