Why Cat Age Calculator?

Understanding your cat’s human age helps you:
✔️ Monitor their health at different life stages
✔️ Provide appropriate diet and care
✔️ Know when they are in their prime, middle age, or senior years

Traditional Cat Age Calculation

The traditional formula follows these rules:

• First year of a cat's life = 15 human years
• Second year = +9 human years (Total: 24 years)
• Each additional year = +4 human years

Cat Age (Years)	Human Age Equivalent
1	15
2	24
3	28
4	32
5	36
6	40
7	44
8	48
9	52
10	56

Scientific Cat Age Calculation (2024 Formula)

Recent studies suggest that cat aging is not linear. Instead, it follows this logarithmic function:

Human Age = 16 × ln(Cat Age) + 31

This method is based on feline epigenetics and gives a more accurate conversion.

Kitten-Focused Method (For Younger Cats)

Since kittens grow rapidly in their first two years, this method emphasizes early development:

• 0-6 months = Equivalent to 10 human years
• 6-12 months = Equivalent to 15 human years
• 1-2 years = Each year adds +9 human years
• After 2 years = Each additional year adds +4 human years
