How old can cats live up to in human years?

There's no single, perfect answer to that question because cat lifespan varies greatly depending on many factors like breed, diet, environment, and healthcare.

Here's a general guideline:

* Average lifespan: 13-17 years

* Longest recorded lifespan: 38 years (although this is incredibly rare)

To give you a better idea of how cat age compares to human age, here's a rough conversion:

* First year: Equivalent to roughly 15 human years

* Second year: Equivalent to 24 human years

* After the second year: Each year is roughly equivalent to 4 human years

Keep in mind: This is just a very rough estimate. A 10-year-old cat is not the same as a 40-year-old human.
