Formula
Human age =
• 0–3 months: Month ÷ 3 × 14
• 3–12 months: 14 + (Month − 3) × 1.5
• >12 months: 27.5 + (Month − 12) × 1.2
These conversion factors reflect typical golden hamster development. Adjust for dwarf species by consulting rodent specialists.

Hamsters reach adulthood within months and transition through life stages quickly. Monitoring human-age equivalents helps you schedule vet exams, adjust nutrition, and create age-appropriate enrichment.
Keep a growth chart noting weight, behavior, and health checks to anticipate senior needs such as softer bedding and gentle play.
