You might be surprised when you get back.  Your cats may well have
tranferred their affections by then to the new food provider and be
perfectly happy.
Boyfriend, the scaredy-cat who would never approach anyone but me until I
had to go into hospital now winds himself around Stan's legs.  He did it
this afternoon too even though I am now feeding and caring for him again.
Fickle boy.
Kitty FC, although apparently the ringleader in going round to Stan's house
to remind him he was late providing dinner, does no such thing.  It would be
beneath her to suck up to a stranger in that kind of way, although she
hasn't survived so long in the out before she got her onetruehome here
without knowing just how to appeal enough to someone to give her just a
little something..preferably every day ;-)
What I am trying to say is that your kitties will be fine, it is certainly
true that we need them more than they need us and you have people in place
to look after them that must surely be compassionate.  Why else would they
be medical students?
