Not good news, but not horrible either. Friday night she seemed better. More active, ate some food, pooped and pee'd in the litter box. All good signs. Come Saturday morning a decline again. Took her out, gave sub q, force fed a little and brought her outside. She was weak.
Called my trusty rescue who has never failed me (thank you G!). I explained the situation and advised that financially I could no longer do it. She intervened and made an immediate appointment for me. We went to the vets and we discovered that the meds prescribed by the other vet was contaminated and out of date.

. They assured me that this was not the culpret but certainly did not help the situation either. She is hooked up on IV but she is urinating so much now. They feel that there is a problem with one kidney. Blood panel is scheduled today to find out what is wrong internally.
Prayers required please. I asked the clinic to name her which they did: Olive. I figured I really needed for her to have a name as she is important.
Thank you all for great advice. I indeed put food on her little legs and also she was on the food as indicated by RustyCat which my neighbour gave me. It seemed like the only one she was interested in. Go figure.
Again - thank you all so much. More wonderful vibes required for Olive.
