For those following our saga...
Peewee is doing poorly.  He was at the vet all day Fri PM and
yesterday.  Yesterday he ate some, and seemed perkier by 5PM last
night.   Of course, since these things happen at the worst possible
time, DH and I were OOT on a much needed vacation.  I got a call in
the middle of breakfast this AM from the vet to tell me that overnight
he vomited everything he ate plus green bile.  It looks like he might
be blocked - either from a mass or a blockage. We drove home
immediately.   I am picking him up this PM to assess him, and then
will transfer him to a feline specialist for assessment/diagnosis in
the AM.  I'm not prepared to put this cat through surgery, so
euthanasia may be the choice we make.  This is all so very sudden and
heartbreaking.  Any positive, healing thoughts you have for either of
us would be greatly appreciated.  I love this cat almost more than
life itself.
