I did have my name as Luisa but thought crazycatlady reflected my character better
The feliway sounds like a great idea. It restored harmony with my cats when I introduced a new kitten.
Also, I can't remember if you said but a wee dish of water may be an idea too.
I had a trip from glasgow to edinburgh in the summer and needed to stop at a petrol station and cut up 2 cardboard coffee cups to make 2 little water dishes. It was the summer though and probably not a problem in the winter.
