Update on prior post elsewhere - in case y'all read it on alt.med.vet - here's
the old post, corrected and with additions - I've been looking on the net for
info, but I still need informed opinions from outside -

Just got back from the vet - he diagnosed my 5-yr old spayed female Siamese cat
as having kidney failure, was going to keep her 48 hours and push IV fluids
through her, said that if there is a 50% decrease in current BUN & creatinine
values then further treatment will be indicated. He did not talk about what if
it's not decreased. But if the values did go down that much, then he'd want to
keep her another 3 days, continue fluids, then send her home for me to continue
SQ fluid and give her a special diet - low amounts of high-quality protein. He
said that because she is Siamese it's likely a genetic defect, and that she's
only 5 suggests that it's a bad defect.

That was on Wednesday - yesterday, they did an ultrasound and said the kidneys
look normal size/shape.

On Weds, she was dehydrated but most values on Superchem 200 Profile 2 were in
normal range - here are the others, as of Weds:

BUN is now 148 (ref range 14-36)
creatinine 10.0 (ref range 0.6-2.4).
Na, Cl, and Ca are just barely lower than the ref range, potassium is normal,
Na/K ratio is normal
GGT is high: 13 (ref 1-10)
Phosphorus is high: 26.2 (ref 2.4-8.2)
Amylase is 1588 (ref 100-1200)
Osmolality is 347 (ref 299-330) maybe just dehydration?
CBC is normal except the PCV is 26 (ref 29-48), so I guess the kidneys are also
not putting out normal levels of erythropoietin.
Neg for FeLV & FIV, 1:400 titer for FCV.
Physical exam - he said the anterior abdomen "just didn't feel right", though
he felt nothing specific wrong - ie no masses. She had been listless for 2-3
days - no other symptoms at all - she had lost 1 pound of weight, but we'd been
trying to do that - she had been 9 pounds, and had had just a little excess
tummy.

Now on Friday, the BUN & creatinine have not gone down as much as hoped - BUN
is 80 compared to 148 on Weds (ref 14-36), and creatinine is 7, where it was 10
(ref 0.6-2.4).

I think the vet wants to euthanize - he did not today talk about treatment,
said the prognosis is not good. I won't do that, at least not until I'm sure
she can't come back from this and have a good life at least for a while. But
how bad off is she really? She is peeing but not eating - but then she's been
on glucose in the drip at first and now lactated Ringer's.
