Well, Rex has been back home 3 1/2 days now. He is back to about 90%
of his normal routine. The only problem I see is that his appetite is
very low. He drinks normally, but will not eat properly. He used to
only eat dry food, but won't go near it anymore. I have tried various
canned food (warmed in microwave) and when I bring it near his face,
he starts to salivate. He sometimes takes about 20 licks of the food
then shrinks away from it. After licking the food, he is constantly
licking his mouth. I have syringe fed him (orally) once and got some
Hill's A/D (high protein) food into him. It's distressing for both of
us to feed him this way, but the vet has cautioned me about liver
disease developing, after a cat doesn't eat for a few days.

The first day, he didn't vomit. On the second day I noticed that he
had vomited out some bile, and a piece of kibble. I told the vet, who
was surprised that he had vomited again. The next day, no vomiting.
Today, I tried to offer him some Hill's A/D on a plate and he took a
few licks of it. Then he withdrew away from the plate, and vomited out
some bile. It seems that every time he eats some solid food, something
makes him feel nauseous. He drinks water without any problem. He can
even tolerate getting the liquid antibiotic into his mouth (by
syringe) without vomiting.

I am still waiting for the vet to call back about the endoscopy
results from the lab. Later, I will try offering him another variety
of canned food and some food from those sealed pouches.

Am I being too impatient in Rex's recovery at home? Am I doing enough
to help him? I was thinking about offering him baby food (without
onions), but I noticed that they contain lemon juice. Is that safe? I
just hope that if he has some condition, it is treatable.
