How many times can you write CAT?

This is a bit of a trick question! You can write "CAT" an infinite number of times.

Here's why:

* No physical limitations: Unless you run out of paper, ink, or time, there's no physical reason you can't keep writing "CAT" over and over.

* No mathematical limit: There's no mathematical limit to how many times you can repeat a word or a sequence of letters.
