Well, Kami and I have arrive at our destination safe and sound, and
mostly sane.  It wasn't as bad as I expected.

To begin, I purchased a harness and leash for her.  She wanted
nothing to do with it and scared me a few time while she was trying
to take it off.  Nonetheless, I insisted she wear it, and since she
was in the carrier in the front seat, I could keep an eye on her.  
But that eventually changed... a couple of times.

When the mover came I shut her in the bathroom.  It was the one
place they didn't have to go and she would be upset, but safe.  I
put a big sign on the door "Cat/Gato Inside" so no one would open it
without checking with me.  After they had gone, she was in shock
when she came out and the apartment was empty, save a corner full of
stuff that was going in the car.  It had to take it to the car in
about 10 trips and as I kept leaving with stuff and not her, she
became more and more concerned.  But she was in the last trip.  The
worst part in this segment was that I overestimated what I could put
in the car because of the space the covered box, carrier, and
preserving the front seat for her.  I tried every which way, but I
had to leave behind my most favorite (and only) plant in the parking
garage--a ficus midnight that was only a foot tall last year, but
was now four feet tall.  It just wouldn't work.  It was the only
thing that made me cry as we drove away.

Kami's M.O. is to howl piteously and pee in the carrier when we go
to the vet.  She started to howl but stopped right away and did NOT
pee in the carrier.  Somehow I think she knew that wasn't where we
were going and she settled to see what would happen next.  "Next"
was a stayover at my sister's house, an hour and a half drive.  A
good go at seeing how she would take the car ride.  She did okay,
but would not eat or drink, and didn't use the litterbox until early
in the morning.

We had one false start.  She decided to pitch a fit once we hit the
road and I pulled over and offered her food... no, water... no,
litterbox... yup.  She pooped.  That is SO not a good thing in a
Honda Civic.  Back underway, she still was not at all happy to ride
in her carrier in the front seat.  I finally opened the door and put
my hand inside, which she rested her head on, but I could drive for
two days with one hand.  But, when I didn't have my hand in there,
she would crawl into my lap.  I decided to skip the carrier, which I
jammed in the back, and let her lay on the seat.  She could stretch
out better.  But then she started complaining that the sun was in
her eyes and she was terribly distracted by overpasses and trucks.  
It's not like she couldn't lay the other direction, but you know
kids...

After a few hundred miles of her complaining about her seat, I had
enough.  I rearranged the car again determined that no matter how
much she complained it was going to be ignored.  I stuck her in the
carrier place behind the seats, in the middle.  It was higher up and
she could see out the windshield.  I didn't have another problem
after that as long as I left the door open.  In fact, the door kept
swinging shut and she starting sleeping with her paw out propped on
the door to keep it open until I got something to jam it that way.  
Not the safest thing in the world for her, but she was content.  
After that, every once in a while she would try to step out onto my
shoulder and I would pull over and offer water, which is all she
wanted.  After she drank her fill, she moved back to the rear of the
carrier and settled down to nap again.  

I offered her the litterbox a few times, since she seemed okay about
using it in the car, but all she did was lay down in it.  I was NOT
going to let the cat travel in the car sleeping on her litter.  I
had to pry her out again every time.

I was concerned that, even though she drank, she didn't want to eat
anything.  I figured it was better for her to eat "bad" food than
not, so we got chicken nuggets--me 5 and her 1.  

I got in and out of the car many times for various things, and she
didn't budge.  In fact, she wanted to sit in there and groom and
started fighting with the harness again.  I finally took it off
sincfe all I had to do was shut the door when I had to.  Eventually
I didn't even do that.  She felt very safe and didn't even get out
of the carrier when I was in the store for 15 minutes (no problem,
since it was totally frigid outside).  When we arrived at the motel
the first night, she waited patient and I took three trips to the
room with cooler, pillows (I like my own pillows) and finally her
litterbox and carrier.  She only drank a little water and wouldn't
even take the food.  Luckily, I didn't eat have a nugget and had
stashed it in the cooler.  She ate and then took a really long pee
and flung litter three feet out the hole in the booda.  I left a
note of apology for housekeeping.  First day of driving was 11
hours.

The next morning she wasn't too keen on getting back in the carrier,
but was quiet after she knew there was no point in resistance.  She
finally settled to watch out the windshield with her paws princess
crossed.  After a little while she went to napping.  Drive, drive,
drive.  Still not interested in food, so after filling up on gas
again, I went through McD's and ordered my combo meal and a plain
burger patty.  No, not a hamburger.  No, no cheese.  Just a piece of
meat for my cat.  Yeesh, finally.  They didn't charge us for that.  

Waylaid by storms, it appeared we were not going to arrive at the
apartment before the office closed.  I called two hours before they
would close and explained what happened.  They said to call again in
an hour, and so on.  I then explained that I have nothing against
staying in a motel another night and signing the lease the next day,
but I was concerned about my cat.  Could I just get in the aprtment
and do the paperwork in the morning?  No.  Drop off the cat with
food water and box and stay elsewhere?  No.  Finally they said they
were stay until I got there, stop speeding, and they were preparing
everything so I could sign off as long as I was willing to do it
without reading.  I agreed.  We arrived at 6:15, 45 minutes late (I
kept speeding--a pretty steady 90 mph).  Driving time: 10 hours.

Kami thought it was another stopover and was still pretty upset, but
now 24 hour later she's getting used to the idea that we might
actually be staying.  I sprayed Feliway on every corner before
bringing her in, so that might have had an effect.  Who knows, but
she was a trooper about the roadtrip beyond expectations.  She's an
oldie, but never ceases to surprise and amaze.
