How this category's numbers were calculated

The dog-safe and cat-safe percentages, the 15% unsafe-or-toxic hazard share, and the low hazard tercile are all computed live from every food in this category's food-safety archive rows -- counted directly, never estimated. The tercile cut points come from the same computation run across every category, so "low" means this category's hazard share against the OTHER categories' actual distribution, not a fixed threshold.

Individual food pages cite the FDA or ASPCA Animal Poison Control Center by name when that authority's own list names the food; rows without a named citation are PlainPetFood's editorial compilation from published veterinary toxicology guidance. See our methodology page for the full process.

Editorial compilation; authority for the foods it names: ASPCA Animal Poison Control guidance, veterinary toxicology references, and AAFCO. See our methodology. Compiled and reviewed by PlainPetFood.
