Regarding emails betweent pet company, and realtors and jobs applied for how many emails is enough?
In all seriousness, if you haven't done - make a cover page that is basically a list of stuff in the package.
The job is to make it easy for them - cover page bullet points has eg a point "Moving arrangements - pets - correspondence regarding cat transport." And etc, point by point.
That way what the officer is seeing is that you have a list, they can jump to document four (or whatever), and see it is some sort of moving arrangements for the cats.
The point is: don't make them read all this correspondence in detail - they don't want to and will put it off if they have to wade through it all. They look at the heading on the cover page, check to see the document is there, and what it is about. They might look at one or two documents in detail and leaf through the rest, but basically use your cover page to let them see
arrangements are being made and their check is mostly done.
Save them time and make their job easy and there's a better chance it will get done quickly without being assignd to the pile of Dostoyevsky novels to get to someday.
