How many Cat years to Human Years?
There is no direct formula as such but this can be used as an approximation
Human age = (Cat age - 2) x 4 + 24 use this for cat age > 2
- The first year of a cat is equal to 15 human years. The 2nd year of cat is about 9 human years
- From the 3rd year onwards, it is equal to 4 human years
- This means that a 5-year-old cat is 15+9+4+4+4=36 human years
