Understanding Pet Age Calculations

Pet age calculation is more complex than the old "multiply by 7" rule. Different animals age at different rates, and even within species, factors like size can affect aging:

Dogs:

  • First year equals 15 human years
  • Second year adds 9 more years
  • Subsequent years add 4-5 years depending on size

Cats:

  • First year equals 15 human years
  • Second year adds 9 more years
  • Each additional year adds 4 human years

Other Pets:

  • Rabbits: Each year equals approximately 6-8 human years
  • Hamsters: Each year equals about 14 human years
