I partially followed your suggestions by getting rid of str.replace(old,
new[, count]) and new_output = ' '.join(user_input). But I also wanted to
try to get this to work without simply copying your code.

       I don't think I made my intentions clear. I don't wont to increment
each digit. I want to find each number (for example, if the str contains
436, I don't want to interpret that as 4, 3, 6 - I instead want to
interpret that as 436, which is why I created a list and then joined back
into a string afterwards.

And my output was:

I  got 433 when I counted, but Jim got 434 which
is a lot for only 7 cats, or were there 13 cats?
