My family and I have moved to the UK and our cat is being looked after
by friends until she fulfills all of the requirements to not be
quarantined in the UK (it will take about six months). She is about
ten years old and has been separated from us for about two weeks. We
just received an email from our friends and apparently our kitty hides
under the bed all day long and only ventures out to eat. The house in
which she is staying has a kitten and a two year old cat. The worst
part of it all (apart from the fact that she is petrified all day
long) is that she has started urinating and pooping all over our
friends' apartment.

Thanks for any help in advance.
