Our Calculation Methodology

Our pet age calculator uses data and formulas based on extensive research and authoritative sources:

  • Dog age calculations are derived from a study published in Cell Systems journal (2019) by researchers at the University of California San Diego School of Medicine.
  • Cat age calculations follow the guidelines provided by the American Animal Hospital Association (AAHA).
  • For other pets, we've consulted various veterinary resources and species-specific studies to provide the most accurate estimations possible.
