How Pet Age Conversion Works
🐕
Dogs
The AKC-based formula considers breed size. Small dogs age slower in later years; large dogs age faster.
🐈
Cats
First year = 15 human years, second = 9, then 4 per year after. Indoor cats live 12–18 years average.
🐇
Rabbits
Rabbits have a 9:1 ratio to human years. A 5-year-old rabbit is ~45 in human years.
🐹
Hamsters
Hamsters age very rapidly — 25 human years per hamster year. They typically live 2–3 years.
