This is not one of those things you can predict in advance.  It depends on
circumstances and the reactions of your cats.  That said (which I realize
basically says "nothing"), I would expect that two months will probably be
enough time.  I always keep some extra Feliway on hand just in case it is
needed.  For example, I use it when I leave on vacation and have a pet
sitter even though there have never been any problems.  I used Feliway for
about 2 months when I first adopted Duffy and did not need it after that for
routine use.  If your cats seem agitated, though, I would use it until they
seem relaxed and "settled in."

I've got enough for two months, do you think that will be enough time?

It may worth turning them off every other day, after a couple of weeks, to
make them last longer.

I know how scary that is! My front entry is a couple dozen feet
from a very busy road (I've even had car accidents wind up in the
front yard, mere feet from the house) and the times I've had
escapes were out the front door (and two from a front window).
Shamrock escaped when I had some work being done, and the guy
didn't shut the storm door all the way, and Shamrock nosed his way
out. I didn't know he was gone for about a half hour.  Found him in
the next door neighbor's yard, and he ran from me when I tried to
catch him. Luckily he ran into my backyard.  Shadow (RB) fell out
of two front windows before I realized they were all insecure.
Ground level, so not a far drop. Again, the first time he was out
for at least a half hour, and I found him chewing grass next to the
driveway. Both of these incidents were fairly soon after moving in,
so things are a lot different now, and hopefully there won't be any
repeats.  The second time he fell out of the front window, I was in
the same room and got him before he realized he was outside. He
just leaned on the screen too hard.

Best wishes and congrats on your new home.
