I meant that it *could be* ringworm even though it doesn't fluoresce. IOW,
the Wood's light is right only in about half of the cases. Many
culture-confirmed cases of ringworm don't fluoresce. IOW, the Wood's light
is not definitive for ruling out ringworm. Sorry for not being clearer.

If it does turn out to be ringworm, speak to your vet about Itraconazole
(Sporanox) - its about the best drug for ringworm there is and very easy to
administer.
Let one of those little restaurant-type butter tubs melt down at room
temperature, then thoroughly mix the 100 mg capsule in the liquified
butter - then refrigerate. When butter becomes solid, cut the cube into
four or five equal pats - each piece contains an equal amount of drug -
i.e., 5 pieces @ 20 mg ea. A 4 kg (9 lb) cat usually gets 40 mg/day (or
whatever your vet prescribes) - so a 9 lb cat gets 2 pieces. You can cut
those 2 pieces into smaller pieces if necessary so that the cat can gobble
them right down. Most cats just love butter - and the fat increases
absorption of the drug.

Actually, that's not a bad price considering the blood sample should be sent
with a cold pack via overnight courier.

If he is hyperthyroid, put him on a reversible tx *first* (e.g.,Tapazole)
for a few months and monitor his kidney function. If his kidney function
remains stable while he's on Tapazole, you can probably go ahead with I-131
radioiodine tx. This is a safety precaution because I-131 is irreversible.
Hyperthyroidism increases glomerular filtration rate (GFR) and renal plasma
flow which can mask chronic renal failure in cats with underlying kidney
disease. After hyperthyroidism is treated, GFR could drop to its true rate
causing clinical develoment of overt renal failure in cats that have
underlying (and undetected) kidney disease.

Keeps us posted. When I don't hear back from people, I tend to fear the
worst.
Best of luck

Oh, I know - I'm not being very clear myself. I actually suspect it
*is* a non-fluoresceing dermatophyte.

Thanks for the tips! I will ask her about the drug.

The lab that had his sample was going to run it from the blood they
took the other day - I guess they had enough serum left.

Ah, yes - I-131 - I always say 151. I think I do that every time I
post, LOL!
I think tapazole would be first-route of treatment for him, as well,
eventhough I think it is a crappy drug. Where as radioiodine is a
cure...

If he had underlying kidney disease, would it show on bloodwork NOW,
and could the vet detect abnormalities with palpitation? His kidney
function looks good from the bloodwork we did Wednesday.

Well, I'm sorry to say, it is worse. :( He vomited last night (fur
ball/bile) and has diarrhea and won't eat (did eat a couple kibbles of
chow). First time in 12 years that this cat has refused food. I
called the vet - I am observing him today, and may go in this evening.
