A popular misconception is that cat age seven years (in human years) for each calendar year. In fact, feline aging is much more rapid during the first two years of life .
A cat reaches the approximate human age of 15 during its first year, then 24 at age 2. Each year thereafter, it ages approximately four “cat years” for every calendar year. Thus, a 5-year-old feline would be approximately 36 in cat years
