Hi Everyone,
 Thank you all for your kind words -- you really helped me.
I'm feeling much better now -- last night I got a phone call
from one of the adopters, to tell me how thrilled they are
with the little cat, how their mother (who hadn't seen her)
adores her and marvels at how self-confident she is, how the
little thing loves scampering around their house, exploring
every corner and tossing her toys around!
 Apparently one of the adopters lay down on the couch for
some time yesterday, with the little cat sound asleep on her
chest.
 The resident cat growls at her, but isn't aggressive, and
the little one doesn't seem to mind. So that looks promising.
  I know that she'll fade away as other fosters come to
take her place -- that's another comfort I have.  I keep a
journal of all the cats who come to our house, with a photograph
and a description, and something about their forever homes, and
it's nice to look at that.
