My French is rusty, but for those who don't speak French, she is basically
saying that she has 3 adult cats and she is taking a trip in the Spring with
them.  She is saying where she lives now - mountain of Valais or something?
She is anxious about the trip - 200 km by car to Geneva, then a plane to
Athens, possibly through Zurich, and then from Athens, takes a boat to
Piree.  She wants to know how to prepare (for the cats) and has anyone been
through a similar situation.  She says you can reply in English, Greek,
Italian, or French.

I'm just translating, I'll leave it to someone else who can help to reply.
