📊 Cat Age to Human Years Conversion Formula
Cats mature rapidly during their first two years and then age more slowly afterward. Veterinarians generally use the following formula:
- First cat year = 15 human years
- Second cat year = +9 human years
- Each additional year = +4 human years
Example Calculation:
If your cat is 5 years old:
15 (first year) + 9 (second year) + (3 × 4) = 36 human years
That means your 5-year-old cat is roughly a 36-year-old human — mature and full of energy!
