Estimate a rabbit's age in human years.
A rabbit's first year equals roughly twenty-one human years, after which each additional year adds about four more. This reflects their fast early development and relatively short adult life. Rabbits reach adulthood in under a year, so scaling their age correctly helps owners schedule spaying, diet transitions and senior care.
