Best Answer

Do NOT use the dog years formula. Cats age more quickly in the first years of their lives.

The first year of a cats life is about fifteen years. the second year is about ten. so by the time a cat is two, it will have reached adulthood. Every year following is about 4 years.

Example: 5 human years = 37 cat years Not 35 cat years (the dog years formula)
