🧮 How the Cat to Human Years Formula Works
Cats don’t age linearly like humans. Their first two years equal a large chunk of human life, and after that, they age more gradually.
Here’s the most accepted formula used by veterinarians:
- First cat year = 15 human years
- Second cat year = +9 human years
- Each additional cat year = +4 human years
Example Calculation:
A 5-year-old cat = 15 + 9 + (3 × 4) = 36 human years
That means your cat is at the prime of adulthood — healthy, mature, and independent.
