How Are Pet Years Calculated?
The old rule of “1 human year equals 7 pet years” is actually a myth! Pets grow rapidly during their first two years of life, reaching adulthood much faster than humans.
- The First Year: A 1-year-old cat or small dog is developmentally equivalent to a 15-year-old human teenager.
- The Second Year: By age 2, your pet reaches full adulthood, roughly equal to a 24-year-old adult.
- Senior Years: After age 2, each pet year equals approximately 4 to 5 human years, depending on their size and overall health.
