Calculators first
Pet Age HQ
Turn pet years into human-equivalent estimates with cited models — epigenetic math for dogs, size charts from veterinary handbook lineage, and AAFP/AAHA life stages for cats.
Why not “multiply by 7”?
Dogs mature much faster in the first years than a flat 7× rule implies. Wang et al. (Cell Systems, 2020) mapped DNA methylation across Labrador ages to a logarithmic curve. We show that estimate beside a size-based veterinary chart so you can see both — and the myth for contrast.
Nutrition, cited
Label literacy, homemade-diet evidence, carnivore biology, and FDA’s DCM investigation language — criteria pages, not brand rankings.
Pet insurance (education)
How policies work, NAPHIA average premiums, and an alphabetical attribute table — not recommendations.
