Cat psycology question:

If you're making major changes to your cat's life - say, putting her
into a cattery/quarantine for two months because you're all moving to a
new foreign country - how best to do it?

One way would be to keep things as normal as possible, keep all her
"stuff" until the last minute, which would keep her stress level a bit
lower over time, but might stress her more when she's suddenly dropped
in a kennel.

The other way, which is how things are working out this time, is to
gradually introduce her to the changes.  First her furniture and ours
shipped, then we moved to a new place, but with her regular food bowls
and litter box.  Today we're packing them up.  Saturday she goes to the
kennel.

She seems particularly stressed today, seeking out my clothes and
luggage to lay on/in, which is why I'm wondering if we did the right
thing, introducing her to the idea slowly.  Unfortunately, there was no
other way, unless I put her in a cattery for an additional month.  Would
that have been less stressful than these gradually building changes?
She's been through this before, and I'm pretty sure she has some idea
about what's happening.  After all, this'll be her 4th overseas move.

I'll be desperately worried about her for the next two months, won't see
her again until mid-June.  Augh!
