I'm confused, and this has gotten complicated.  And I'm very worried
about my cat.  Ethel is no longer in heat, it lasted about a week.

I was able to contact the volunteer who transported them AND is the go
between of the Spay clinic.

She says they want to see the cat in heat before another surgery.

I requested the blood work instead, suggested by someone in this
newsgroup, and was told the clinic ONLY did the surgeries and had no
resources, abilities to do the testing.

THE PROBLEMS:  (Red flags for me)
-Turns out this clinic ONLY does surgeries on feral animals.
-The admin. of this clinic is ticked because kittens scheduled for
adoption were 'done'.
-It is only in service for a week end once every two weeks.  (So Ethel
could be in/out of heat again before they have another 'clinic'.
-They have a big trailer (RV) they do these surgeries in, but it's
clear across the county, in another city, from me.  Without a
volunteer, I can't take Ethel.
-Though I've given my name, number, email, I've not heard from any of
these people. (except the ticked administrator).
-The volunteer wants to pick Ethel up and keep her at her place IN A
CAGE, till she goes into heat again along with her 30 or so other
rescue animals.  (NO WAY)
-The vets name can not be found in my state's license list!!!  (Do
unlicensed people do these surgeries on feral animals???)

CONCLUSIONS:
-Ethel needs this surgery.  I can not live in a small apartment with a
cat (who may or may not be able to get pregnant) who goes into season
every month.
-I do not have funds for a private vet.  The one I approached turned
me down cold.  Told me it was too difficult a surgery for him!
-I do not want her going back to either this clinic, vet, or
volunteer!
-I love my Ethel (and her sister Lucy!), want what's safest and sanest
for all of us.

I NEED
-thoughts and ideas from you all
-is there any way I could find (how?) a vet or clinic in my area that
would do this either pro bono or let me make small monthly payments.

STATUS
-I'm ignoring the email from the clinic administrate wanting info till
I find out if I have to have her taken back to that clinic.
-I've told the 'volunteer' that when Ethel goes into heat again, she
can pick her up, take her right in for the surgery on the DAY of the
clinic, not before.  But that could be 13 days after start of heat!
-Am checking out taking cat on public disabled transit, but it would
be a long, two van, trip and I'm afraid it would be a dangerous ride
home, after surgery, for her.
(As I don't see I have any other choice in any of this, yet.)

PLEASE don't 'flame' me about this.  I need help...
