Convert your rabbit's age into an approximate human-equivalent age.
Rabbits mature very quickly in their first year and then age more gradually — this calculator converts a rabbit's age in years into an approximate human-equivalent age.
First year: Human Age = Rabbit Age × 21. After the first year: Human Age = 21 + (Rabbit Age − 1) × 6.
A 3-year-old rabbit is about 33 in human years (21 + 2 × 6).
Breed and size affect a rabbit's lifespan and aging pace — smaller breeds tend to live longer than giant breeds, so treat this as a general estimate.
It applies an approximate ratio based on typical rabbit lifespans (commonly 8-12 years) compared to human lifespan.
No — it's a general approximation for comparison, not an exact biological equivalence.
Many veterinary resources consider rabbits senior starting around 6-8 years old.
