I am looking for some insights or sugestions based on other cat owners
experience with cats with similar symptoms. I left on an over night
trip on Tuesday, my cat Elliott seemed his usual self when I left.
When I came home on Wednesday night he was listless, had diarrhoea and
was vomiting. He has had some short boughts of diarrhea in the past
but nothing serious. I called the vet on Thursday and they saw him.
His blood tests are normal (for a 9 year old), Lymphosytes (sp??) were
a little low but the vet did not seemd concerned. They gave him an
injection of fluid and sent him home. He did not eat or drink anything
on Friday, when I brought him back on Saturday and they admitted him
to emergency.

What I know so far is:
His temerature is normal
He will not eat, or is eating VERY little
He does not appear to be drinking
His blood tests, xrays, and urine tests are all OK
He appeared healthier today but still has diarrhoea
He was not vomiting in the hospital
His vomit was originally white and foamy
This progressed to green after a couple of days
He tends to vomit right after a bowel movement
He was having some inadvertant bowel movement during vomiting earlier
on

The vet seems to be stumped, and I cannot afford an infinite amount of
tests. Has anyone elses cat suffered through this and what was the
cause???
