Actually the first view is the only correct one.  There is not enough information.  There is an old quote from physics, possibly a quote from Einstein, which I don't remember the exact words of saying something like:

"If you can solve a mathematical problem it is trivial.  If it is a real world problem, you can't solve it."

Or as someone paraphrased:

Physics, inasmuch as it is an accurate representation of reality is rarely simple, and when it is simple, is rarely accurate.

You can't fill a room with live reproducing rats.  You probably can't even fill the floor of a room with live rats for any length of time and certainly not by expansion.  (You could take a large group of rats and put them in the room - ie concentrate them - but that's something else.

There aren't three kinds of people.  (Watch out or I'll tell you my two kinds of people jokes.)
