Cats age faster than humans. While people often calculate their dog’s age by multiplying by seven, calculating a cat’s age is a bit different.

At one years old, a cat is roughly equal to a 15-year old human. At two years old, a cat is like a 25-year old human. From that point on, each additional cat year is equal to four human years. So treat your cat well no matter what its age.
