US pet ownership cost reference for 100 dog and cat breeds across the 51 US jurisdictions. Annual food, vet, grooming, and insurance figures are factor products (per-breed baseline × state cost multiplier), anchored to BLS Veterinary Services CPI, OFA disease statistics, NAPHIA industry premiums, and AKC + CFA breed registries. Per-cell values are NOT measurements — see /methodology/ for the verbatim decomposeCost function.
