LIFE STAGE TIMELINE
How is this calculated? Rat-to-human age conversion is approximate. Rats mature rapidly in their first months — a 1-month-old rat is roughly equivalent to a toddler. After sexual maturity (~6 months), each rat month equals approximately 2.5 human years. The average pet rat lives 2–3 years (24–36 months). These conversions are based on developmental milestones rather than simple linear scaling.
